✅Luma: Prey (2017)

[subtle plover]

Before and After

[subtle plover]

I've added a feature to change the SDR tonemapper (Hable) to work in BT.2020, causing much more saturated "filmic" shadow and highlights.

I think it's kinda cool and fits the game.

[valid kiln]

damn look good

[karmic smelt]

looks great

[subtle plover]

Schedule:

• Fix weapon FOV resetting on level loading
• Move DLSS before grading
• Separate UI composition
• Finalize LUT extrapolation
• A few minor things

[lusty moss]

before grading?

[subtle plover]

color grading/tonemapping yes

[subtle plover]

I fixed this. Disabling screen space reflections ended up running a different g-buffer composition shader, which I had never captured, so my code to track the state of the game's rendering would break.

There's a good chance i've missed more though, given that there would be even more combinations.

*seems fine now, i've tested around.

[subtle plover]

Does anybody think that the sun (or starts) are too bring in Prey Luma and can be annoying to see when on screen?

[lusty moss]

do you have screenshots?

[subtle plover]

no, it's about gameplay.

[lusty moss]

so you mean in action?

hmm

yeah idk I haven't played with it

haven't played the game in a long time

despite launching it practically every day lol

[subtle plover]

you don't have an HDR display

so, it doesn't apply to that

[lusty moss]

I don't remember which one I have

doesn't luma do hdr though?

[subtle plover]

if u have an HDR display, yes.

[twin haven]

Hm I didn't notice anything blinding me

[paper scroll]

DX question from someone who’s never done game dev: how do you unit test stuff like what Luma does? Or do you have test manually?

[subtle plover]

I haven't even played the game. People have been testing. But I know what to look for and what to fix upfront generally, from experience

[deft dock]

How can we try the latest version of the mod that's compatible with the shuttle bay fix mod?

[subtle plover]

It's pinned.

[lusty moss]

does luma change the way stands/"info kiosks" display textures?

[subtle plover]

Not intentionally. Is there a difference?

[lusty moss]

well yeah it breaks my edits

I mean I should check again just to be sure but the gray screen is noticeable and it wasn't there before

[subtle plover]

Please do. Otherwise we'll need to fix Luma if there's a bug.

[subtle plover]

With and without Luma?

[lusty moss]

nah

vanilla and touch up, it's supposed to note a hull breach

[subtle plover]

And with Luma it's grey?

[lusty moss]

not just with it, I'm puzzled how it's even come up

it seems to have happened after I installed luma right now

[subtle plover]

Ok so we have no bug

[lusty moss]

it wasn't there before

then I installed it, and it's here. but it's still here without it

which is strange

🤔 also

well actually idk. but some uninstall thing could be neat I guess, idk

[lusty moss]

👍 all good on your end yeah

reverted stuff, something happened on mine at some point

[lusty moss]

pixelated shadows

[lusty moss]

sun is too much, in the apartment view at least

I can't get back to this option if I cycle

[subtle plover]

Yes, it's bad in SDR with Luma.

You can fix it with the advanced options though.

[lusty moss]

how so?

[subtle plover]

Yeah that was bad before Luma.

[subtle plover]

There's an advanced setting called sun shafts look

And tonemapper type

Check the tooltip and change them

[lusty moss]

but I have luma no? the alpha

is it still kind of a thing?

I vaguely recall trying a version from nexus without CL and it wasn't pixelated

[subtle plover]

Ah yes. That's just z fighting i think. It happens without Luma too. I can't fix it.

Without Luma that show is awful. Try it.

[subtle plover]

Yeah?

[lusty moss]

idk it all looks not good

is 0 actually totally how it was in vanilla?

or is it still affected by hdr and such

[subtle plover]

U need to set the tonemap mode to 0 as well.

[subtle plover]

The sun shafts look the same as vanilla with that setting I think. But the tonemapping is still slightly different maybe.

I don't have a full vanilla SDR mode yet.

But overall, the sun is basically in that scene only.

So it doesn't matter much.

[lusty moss]

yeah that looks better

[lusty moss]

is it supposed to look like that?

[subtle plover]

No I don't think so. You might have installed the mod incorrectly

[lusty moss]

(it's the alpha)

also does the dlss affect the UI?

[subtle plover]

No

[lusty moss]

hmm

luma makes the menu text sharper though

what did you do there?

[subtle plover]

Linear blending on the UI.

[celest jewel]

what about the dlss mip map/lod bias stuff or whatever it is

[subtle plover]

I have code for that in Prey.

Literally copy and paste.

[lusty moss]

Hmm, would it work with the item textures?

https://www.nexusmods.com/prey2017/mods/123

The higher res causes jaggies in the inworld loot interface

I could switch to DSR to alleviate that before iirc but with luma it seems to not really work anymore. Well that and I never liked how the menus became so small either

[lusty moss]

Idk if they’re visible here

But I hope you see what I mean

[subtle plover]

Let's not get there. There's nothing you can do specifically on that stuff. 🙂

[lusty moss]

?

[subtle plover]

Yeah. That. Don't worry.

[lusty moss]

https://tenor.com/view/cat-blink-cat-blinking-cat-funny-cat-funny-cat-blinking-gif-27202865

[lusty moss]

you were saying?

[subtle plover]

What happened

[lusty moss]

the jaggies on the upscaled item textures

gone, reduced to atoms

well except in the search interface but I've confirmed even the vanilla textures had that problem there

[cyan ledge]

On v3 alpha think my game was running with vsync (Present(2, 0)) even it was turned of in settings. Forcing it off in Nvidia Control Panel worked.

[subtle plover]

I don't think you can force vsync off in the control panel

[cyan ledge]

Vertical sync option in NVCP.

[subtle plover]

R u sure about that?

Try updating ReShade

[cyan ledge]

Newest reshade. Just retested in main menu Present(1,0) in game Present(2,0) forcing it of via NVCP turns it off for both in game and in main menu.

[subtle plover]

Have you tried to toggle it after boot?

[cyan ledge]

Yes, dint have any effect.

[subtle plover]

Also could you try an older release pls?

[subtle plover]

Try an older build pls

[cyan ledge]

Sure.

Can copy paste over all files?

[subtle plover]

Delete all before.

[cyan ledge]

Tested v2a-testing and vanilla (no mods). In vanilla in game vsync option worked fine while in moded didn't. But it looks like that the game in both vanilla and moded snaps to half vsync if fps drops. It was harder to reproduce in vanilla but fps 1% lows were exactly half vsync lot of time, fps average was only for short time exactly half vsync. This was easier to reproduce with mod.

[subtle plover]

How do you know vsync is on? Do u have dynamic resolution enabled?

[cyan ledge]

Ok tested again v2a-testing. Vsync in game option now did work fine. This time turned on in PresentMon Sync Interval, while vsync was on it was all the time 1 vblk even when average fps would be consistently exactly half of vsync.

In game Adaptive Resolution is off.

[subtle plover]

And with v3 vsync if forced on all the times you say? Even when the perforce is smooth?

[cyan ledge]

Tested v3 again. PresentMon Sync Interval showing that in game vsync option does work. But if vsync was on and I turn it off fps wont go over vsync value even if I reapply settings and change a litle bit fps limit, at same time if I set fps limit under vsync value it will limit fps. Another thing is if I set fps limit close to 1/2 or 1/3 of vsync value while vsync is on PresentMon SyncInterval will show 2 or 3 vblk.

[cyan ledge]

This is on v3.

Also tested vsycn forced off in NVCP, did got fps higher then 165 (up to 240) and on Very High settings even that fps would drop under 165 it wouldn't be locked to exactly 82.5.

[subtle plover]

None of the code for Luma affects vsync

[cyan ledge]

Than it may be issue with the game, cause I did experience these issue without mod to some extent. It was much easier to notice issues with mod I guess.

[cyan ledge]

Think SMAA 1X is not working. It is same if I enable or disable DLSS. Also after game restart the Anti-aliasing option resets to TAA (DLSS Compatible), which does work but looks so bad that I'm not sure that is working as intended.

[subtle plover]

Read the dlss tooltip.

[subtle plover]

It looks bad because dlss is off.

[cyan ledge]

From looks of it DLSS can't be turned off and SMAA 1X used instead of it.

[subtle plover]

Just use TAA with dlss or not.

[twin haven]

TAA becomes dlss

[viral raptor]

Could anyone help me figure out how to stop the new FOV settings from resseting everytime i start the game?

[subtle plover]

Leave the weapon fov unchanged for now. The other fov doesn't reset. We are working on it.

[viral raptor]

Thank You

[soft totem]

hey, just wanted to thank you for Prey's Luma, game looks so much better now ❤️

[cloud geyser]

First of all, I wanted to say thanks for all your work!

Secondly I wanted to report my experiences running the latest test build under Proton. Namely the SDR colour space seems to be having the issue that this file fixed for older versions (gamma being very dark) and given it looks like a lot of the shader code got changed in it's organisation I'm not wholly sure how to go about fixing it myself.

[subtle plover]

You were using the Linux workaround I made for that other user?

[reef thunder]

Hey Pumbo , i'm trying to install the new 1.7 beta version of your mod. When i follow the instructions and place the files to their correspondent location, i get this message when i try to run the game. I'm using the GOG version

[subtle plover]

update reshade

reinstall the game otherwise

clean the mod etc

[cloud geyser]

Yes, it worked for the version on Nexus.

[subtle plover]

are you playing on a steam deck?

[cloud geyser]

Nope, it's my primary OS on desktop. I tried the simple thing of mimicking the change you did on the prior shader to the new version but that didn't get me anywhere.

[cloud geyser]

yep, that fixed it!

[rustic oracle]

hey folks, is this still required when using this with the Epic Launcher Version?

[rustic oracle]

is there a way to make this value editable (or change it directly in any config/file)? I can't seem to click it to change it, and I'd like to try changing it to sRGB since my display runs in sRGB mode and there seems to be massive black crush and banding unfortunately

if there's anything else you people suggest to fix this, Ill gladly take any tips 😄

[subtle plover]

You can edit the value of 1?

[rustic oracle]

i cant, funnily enough

i can edit some values, but not this one

just wont let me click the field to change the value

[subtle plover]

Maybe because you are running in HDR mode?

[rustic oracle]

i dont think so?

[celest jewel]

Reshade ui looks like srgb stretched over pq

[rustic oracle]

yeah, it does look very saturated, ill give you that. Can I change this? (i dont have hdr enabled in windows)

might this have something to do with my monitor being HDR capable (very poorly that is, hence I run it in SDR mode)? this is also the only game where the reshade overlay looks this funky, its usually not this saturated for any other game, looks as it should with everything else

[subtle plover]

Actually you are running in SDR mode I think. So gamma correction is forced.

[rustic oracle]

Hmm, I'm out of ideas then what I could further do. Something appears to be wrong though if I compare my screenshot with the others further up, their Reshade overlay looks normal.

[waxen knoll]

hey everyonee about to try out Luma and I'm about to install reshade. What effects should I install or is standard effects and sweetfx good enough? thankss

[rustic oracle]

I think Reshade is just required because of the Luma Reshade AddOn to inject into the game, anything beyond that should be up to your personal preference.
So you really just need the addon-enabled version of ReShade (you can even untick SweetFX during the Reshade install) without any further shaders.

[waxen knoll]

yeahh thankss just jumped the gun and installed it with both installed and nothing else and it works lmao

[rustic oracle]

Ye, that works, too. Even if you downloaded some shaders with the ReShade installer they shouldnt be enabled by default so the end result should be the same.

[subtle plover]

Linux?

[rustic oracle]

Windows 10

[subtle plover]

Windows 10 is very messy with HDR.

Does your display support it?

[rustic oracle]

yes, it does, hdr is very poor though (IPS panel), so I dont enable it and instead run it in SDR

[jolly loom]

You can change the setting manually in the ReShade.ini, though I can't promise it won't break things or cause issues. Make a backup of your ini first, it's located in Prey\Binaries\Danielle\x64\Release

Under the [Prey Luma Advanced] section, add

Define#2Name=GAMMA_CORRECTION_TYPE
Define#2Value=1

And change the value to what you want.

[rustic oracle]

hey, thank you

that section is just called [Luma Advanced] for me

but I think that might be because Im using the newer generalized version posted on here for epic users?

its the one with all the shaders hashes 😄 is that the correct one?

[jolly loom]

It's possible the name changed. If you change any other settings it should appear in that section, then you'll know.

[rustic oracle]

ill give it a try and see if the value changes in game

[jolly loom]

That's the one, add them at the top like this:

[rustic oracle]

Yeah, the Luma Advanced Section is the correct one, if I change any of the values I actually am able to, it shows up there on the top as you said

however when putting the gamma one in there (one of those I cannot change in-overlay), it just gets removed from the file and ingame is set back to the original gamma_correction_type xD

[jolly loom]

Are you changing it while the game is running? It may overwrite it while it's open, I forgot to mention I did it before launching the game.

[rustic oracle]

is the #n in "Define#2Name" the number that setting appears in the list view in the overlay for you?

because GAMMA_CORRECTION_TYPE isnt the second in the list for me

im wondering if I have to change it to #5, its the fifth in the list for me

[rustic oracle]

no, game was shut down

[jolly loom]

Let me grab a screenshot to compare, it's #2 for me if you exclude the developer option.

[rustic oracle]

this is how mine looks

ill try #4 then 😄

[celest jewel]

Reshade detecting the wrong color space (reason the UI looks messed up) is a recent bug that was fixed in a beta version. Maybe try downloading this version of reshade:

#🧩renodx-dev message

[jolly loom]

I think 4 should be correct for you, it lines up with how mine is numbered.

[rustic oracle]

Yeah, the manually added lines just get yeeted every time, even when set to #4

[rustic oracle]

That sounds promising, ill try that, thanks!

also thank you @jolly loom for trying to help, much appreciated

[jolly loom]

No problem, hopefully Musa's suggestion will fix things up for you. Strange that it gets overridden, maybe there's a check in place in the newest version.

[rustic oracle]

same issue unfortunately, even with that beta reshade version musa linked 😦

ah well, since im out of ideas now and I don't exactly want to buy the steam game version instead of the epic one just to try this, I guess that's it for me and Prey Remastered 🥲

[jolly loom]

I double checked with the newest version and the setting sticks for me weirdly enough. You could try setting the file to read-only before launching.

I will say that the setting does get removed if it's set to the default of 1, but this stuck for me:

Define#4Name=GAMMA_CORRECTION_TYPE
Define#4Value=2

[rustic oracle]

i set it to 0 because i want to try sRGB gamma correction

but that didnt stick either

ill try read-only though

it sticks with set to read only, but its not applied ingame anyways, overlay still shows the setting set to 1

[jolly loom]

That's bizarre. Do you run any mods? There must be a reason it's getting ignored, maybe an incompatibility that we're overlooking?

[rustic oracle]

nope, just a fresh installation of Prey and the LUMA HDR mod

I thought it might be related to my monitor being HDR capable, but me not using it and running SDR instead

but nothing I can think of doing here except disabling HDR in windows (which it already is)

[jolly loom]

Maybe launch Prey with admin rights? I'm struggling to think of why that specific setting won't take. I suppose it's possible that your monitor and Windows could be interacting strangely, but I don't know what could be done to work around that.

[rustic oracle]

I tried launching as admin/without admin already unfortunately

[jolly loom]

I'm at a loss unfortunately. I'll poke around a bit more after work to see if I can think of anything else, it can't be "unfixable"

[rustic oracle]

thats awesome, you dont have to do that though if you got better stuff to do 😄

[subtle plover]

change this

#ifndef GAMMA_CORRECTION_TYPE
#define GAMMA_CORRECTION_TYPE 1
#endif

to

#ifdef GAMMA_CORRECTION_TYPE
#undef GAMMA_CORRECTION_TYPE
#endif
#define GAMMA_CORRECTION_TYPE 0

in Settings.hlsl

[rustic oracle]

I assume you refer to the Settings.hlsl in
PREY\Binaries\Danielle\x64-Epic\Release\Luma\Includes

Changing these lines in there (with the game being shut down, not editing them while the game is running), the value is STILL set to GAMMA_CORRECTION_TYPE 1 in the ingame overlay

[subtle plover]

Doesn't matter. It will look right I think.

[rustic oracle]

well, blacks were still extremely crushed with extreme banding and the ReShade UI still looked way oversaturated, so changing GAMMA_CORRECTION_TYPE apparently didn't have the effect I hope it would.

maybe im just some freak-edgecase of hardware and pc configuration xD

it seems to work for everyone else

[subtle plover]

use the new ReShade musa mentioned

[rustic oracle]

already tried that, same issue

[subtle plover]

set your monitor to gamma 2.2?

[rustic oracle]

yeah, the lagom nl testimage blends in at 2.2 so it seems to be pretty accurate as far as gamma goes

http://www.lagom.nl/lcd-test/gamma_calibration.php

same with the eizo test

[subtle plover]

wait your monitor was gamma 2.2 all along? Not sRGB?

[rustic oracle]

well, it is set to sRGB, but the difference seems to be very small, 2.2 still blends in pretty much completely on those tests.

the black crush and banding is really extreme ingame, that cant possibly be the result of the sRGB <->2.2 Gamma difference

its not minor, its really bad/extreme black crush

and banding in dark areas

just to make sure I'm not just imagining things, everything is fine with no banding or black crush at all again once I rename/remove reshade's dxgi.dll, effectively disabling the LUMA stuff.

I think ill just stop trying to fix this at this point and just play without LUMA. I appreciate everyone that tried to help ❤️

[subtle plover]

https://www.shadertoy.com/view/7sjBWD this is the best test

[subtle plover]

I bet if you update to Win 11 it will fix it

[summer lichen]

pcsx2

[subtle plover]

what about it

[crystal estuary]

Is it normal for screenshots taken while using Luma to be dark (as if trying to view a HDR picture on a SDR monitor) despite not using HDR?

I should note I don't have a HDR display, I was hoping to use Luma for DLAA. (which, I should state, works without issue; also the game looks fine on my end while actually playing it)

[subtle plover]

not sure, use another tool to take screenshots.

[crystal estuary]

Used nVidia App and Steam's screenshot tool. Both had this issue.

Thinking it might be some colorspace-related issue. If that's the case, not really anything I can do due to having a SDR monitor.

[subtle plover]

use xbox game bar

[crystal estuary]

A bit too late, uninstalled the mod. (may try again later though)

[fossil igloo]

Latest Reshade takes HDR screenshots in HDR PNG

[summer lichen]

Sorry, misclicked somehow.

*That reply was for Pumbo. Not used to discord.

[pallid briar]

Is it normal that the game does not fully utilize the gpu. It only draws half the power and útil is at 70%.

[subtle plover]

CPU bound

[pallid briar]

Cpu is at 30 to 60% so that's why I was confusef

On all cores

[exotic rain]

what's the best way to run the Prey HDR stuff with the EGS version of the game?

[subtle plover]

The patch for epic is pinned in the messages

[muted kite]

Not sure if this is the right place to ask but is the prey remastered mod supposed to lower my fps this much, game usually runs at a pretty consistent 144 on very high graphics but after installing the mod it fluctuates between like 40-70 fps

[subtle plover]

Not normal.

[lean basin]

Does anyone else get a random blur over the entire screen every 30 seconds to a minute or so? I thought it was my reshade DOF, but it happens without reshade.

[lusty moss]

do you have adaptive resolution on?

[wintry kestrel]

I'm having some issues with performance (GOG version) and wondering if expected? Without the reshade addon (all other fixes from your file) in a scene im able to get hit the 240fps cap with 85%GPU util (177W) and 38% CPU util. With the addon, I'm only getting 101fps with 84% GPU util (100W) and 24% CPU util (rx 9070 and 5700x3d). Seems something is causing some under utilisation. Going to try with the steam version and see if reproducable. Tested with no other mods and fresh install. Also with optiscaler on and off
EDIT: Same performance in steam version

[subtle plover]

Try two things.
Try with reshade (addons version) installed but without Luma.

Then try to disable the new AO in the Luma advanced settings.

It's the most expensive feature.

[wintry kestrel]

Thanks for that Pumbo will give it a go! (Mod does make the game look amazing)

[wintry kestrel]

Yea no luck improving unfortunately. With reshade addon version and no luma getting the same fps as vanilla. With LUMA even if I disable every setting in the advanced menu and reload the shaders still getting the same performance as with everything enabled.

[fossil igloo]

Try disabling the included Reshade addons and no shader FX

[subtle plover]

Ok. Are you using the last version pinned in this channel, or the one on nexus? Try both.

[wintry kestrel]

Yea tried both again to no luck (also tried different reshade add-on versions from 6.3.3 to the latest pinned unofficial 6.4.1. Also disabled the unneeded add-ons and no FX. Seems odd. I don't think I was having this problem before with my 3060ti so it could be something to do with a 9070 (sold so can't test it out). I might try a different LUMA mod and see if I get similar behaviour as could be a weird driver thing. RenoDX mods are all working normally.

[subtle plover]

Try the development version from nexus and to unload shaders. Is then the performance fixed?

[wintry kestrel]

Nah same issues with unloaded shaders. I do notice however that the GPU usage improves while CPU usage remains the same. Fps also stays the same.

Yea does seem to be something is making it so the CPU is under utilized on my end with the mod. Facing a wall making it GPU bound I'm able to get 200fps at 91% GPU usage and 219w (CPU usage goes down to 21%). As soon as I turn around FPS drops to 60, GPU utilisation goes massively down but CPU util seems to cap at like 27%

[subtle plover]

If unloading shaders has bad performance, then it's something really weird and likely stupid.

It's not connected to amd or Nvidia gpus, because the execution of the cpu code isn't affected by the gpu.

The mod doesn't do anything basically if shaders are unloaded.

[bleak hill]

Chiming in with the same issue:
I recently got a HDR monitor finally and I wanted to try this mod for my first playthrough of Prey. The mod is amazing, but something is hampering performance.

Looking out at the skyline in the first room I'm getting 75fps with Luma, and 150fps if I disable the mod in Reshade and restart.
CPU usage remains the same at 30-35% and core utilization looks to be the same whether its on or off. GPU utilization takes a dive.

5700X3D , 32GB 3600mhz DDR4 on an updated B350 Strix. 7900 XTX (driver 25.5.1). 4K 165hz monitor.
Luma v2a. Reshade 6.4.1 add-on version with nothing but the base features.

Tried, with no effect:
Setting SSAO and SSR to vanilla.
Test version unloading shaders.
Disabling Steam overlay.
Disabling SAM.
Disabling Windows scaling.

I also need to alt+tab after starting the game because of a black screen.

[loud idol]

the mods is better on Nvidia GPU than AMD GPU due to DLAA+DLSS
i try to use optiscaler for FSR 3 but it's complicated

[tender osprey]

you guys made me curious. I should have the game on GOG. I have a 5800X3D and a RX 6900XT, gonna try when I arrive home from work. But it's wild that one goes from 240 to 101 with a RX 9070 and 150 to 75 with a 7900 XTX with just Luma.

The impact seem massive. And I have Luma installed on Kingdome Come Deliverance and I don't think I have terrible performance there

[subtle plover]

Thanks. I will look into when I can.

[tender osprey]

I can confirm what the others are having. There is something seriously wrong with the mod.

Checked on my game, set everything max apart from SMAA x1, 1440P with a 5800X3D, 32GB @3600 Mhz and a RX 6900XT. All data taken with Intel PresentMon so I can check if there is a bottleneck somewhere. Just checked inside the room at the start of the game.

1. Vanilla 281 FPS, GPU utilization at 96%, CPU utilization at 26%. GPU enters wait time (around 1ms) so it means that there is a slight CPU bottleneck.

2. With the mod it went down to 115 with a GPU Utilization at around 72%, CPU Utilization at 23%. GPU enters a longer wait time ( 2.5ms) than before.

@subtle plover

[novel spindle]

Im using this mod with chairloader and its crashing after like 15 minutes everytime, any solutions ?

[subtle plover]

the version from discord?

what's the crash?

[novel spindle]

yes discord version it crashes to desktop saying prey.exe stopped working

but it depends on locations its not always 15m

[subtle plover]

though it's working for quite a few others so

please try all combinations

and see if there's anything specific to it that might cause issues

[wintry kestrel]

Hey team, I find that when I try to use this mod on linux reshade stops working. I've tried following all the winetricks etc from the pinned post but no luck. WIthout the mod install, reshade opens as expected and i get the GUI. But as soon as I install the mod cant open the GUI which i believe means its not being loaded

[wintry kestrel]

Have worked out a little work around which is just to install the binaries folder. Have access to the reshade GUI and HDR is working. Not sure what issues not having the other files will have though haha

[subtle plover]

sorry i don't know about linux

[covert raven]

working fine for me under linux, just nevermind the performance (fsr4 + rdna3 is pretty but runs terrible, great as a novelty though, lol)

[wintry kestrel]

Yea something weird is going on for me haha. You didnt have to make any changes other than whats on the pinned post?

So turns out when I install It on the steam version all is fine, but not on gog via heroic. Weird!

[tawdry niche]

Hey, anyone here who also tried this mod with the shuttle bay fix, which needs the touch-up mod, which needs the chairloader? Game crashes for me instantly

[subtle plover]

#1262582420239286372 message

[cyan perch]

hi

how do you use optiscaler with this mod

i can either install reshade or optiscaler, but if i install both it does not work

[lilac bridge]

https://github.com/cdozdil/OptiScaler/wiki/Compatibility-with-other-mods-(Reshade,-SpecialK)

[valid kiln]

Rename dxgi.dll as d3d11.dll | and optiscaler.dll as dbghelp.dll

[rich swan]

I tried it on my steamdeck and it works now (wasn't at launch). Everything is great except a few things. When changing the mod settings in the advanced tab on reshade the game crashes. I wanted to reduce the quality of some settings (AO and SSR) because the performance hit is severe on the steamdeck but I can't do it at the moment. Is there another way ? Another issue is the AO is very noisy. The mod recommends to install DLSS to help with that but no DLSS on the steamdeck. I tried to install optiscaler to use FSR3 but the game doesn't load in that case when the mod is installed. Anybody managed to change the mod settings on the steamdeck and also use optiscaler with FSR 3 ?

[subtle plover]

Search in the chat above, there's many people that did it

[rich swan]

I found answers to change the setting files directly. I also see some people managed to use optiscaler on linux but the same process doesn't work for me. I was looking for people who specifically managed to make it work on steamdeck, maybe they have the answer.

[eternal sand]

hello, sorry to ask but this is the first time i'm playing prey and wanted to try playing with this mod

is the alpha build that's posted here the last build or is there going to be an update soon ? just wanted to know if i could wait a bit more for final build

[subtle plover]

the alpha is just fine

go with it

currently stuck with other work

[eternal sand]

alright thanks for the hard work put into this already

[knotty grotto]

tried that, reshade definitely loads but i can't get the reshade pop-up/menu to show

so i can't configure anything

also the mirrors don't work lol

[knotty grotto]

i might be a bit dumb i forgor mirrors don't even work in stock prey

[ivory agate]

Don't know why, but the Peak Nits slider resets back to 775 every time I restart the game. My display has a peak brightness of 1,500 nits, if that helps.

[subtle plover]

what does that mean?

[subtle plover]

are you sure your monitor is 1500 nits?
That's what Windows defaults the calibration to when it has no data.

[ivory agate]

Yup. Even most other RenoDX mods will default to 1,500, and Special K will when I occasionally have to use it.

[subtle plover]

We all use the same code to detect the display brightness

[ivory agate]

Hmm.

[subtle plover]

775 isn't hardcoded in Prey Luma

so maybe you put it there

or maybe that's actually the display calibration value from Windows.

[ivory agate]

More likely the latter than the former. The annoying bit is the resetting of the value in between game restarts, honestly.

[subtle plover]

check the config file.

[ivory agate]

I will when I have a sec.

[knotty grotto]

its been a while and i forgot the mirrors in prey don't actually have reflections, i spent like 2 h trying to debug it before i remembered its always been like that

[subtle plover]

Did you leave a comment on nexus about it too?

[knotty grotto]

nah that wasn't me

i saw it tho

i came here searching to see if that guy ever got an answer lol

[knotty grotto]

this is the bigger issue tho

optiscaler seems to be the only way to fully configure the DLSS stuff, however it makes reshade not have any accessible menu

[subtle plover]

Ok. That sounds like a problem with OptiScaler though.

[knotty grotto]

am i doing something wrong? no one else has reported it on the optiscaler github

[subtle plover]

i don't know. I don't use OptiScaler. I'd ask them though.

[knotty grotto]

wait then how do you change the dlss settings on luma hdr?

[subtle plover]

because it says FSR?

[knotty grotto]

there's like a toggle for it but no way to say like "enable dlaa" or change the dlss presets

[subtle plover]

I put a test if the optiscaler/FSR DLL are loaded.
All it does is change the name in the UI to FSR instead of DLSS. Never even tested it.
Glad to hear it works if it does.

[molten wharf]

@subtle plover should i use real light ?

[subtle plover]

I never tried the game without it

nor made a comparsion, nor seen one

[molten wharf]

without reshade version or first one in download section

[subtle plover]

I specified in the readme which one to get I think

without ReShade, that's got SDR ReShade post processes.

[lilac bridge]

You can also try renaming the reshade dll file to d3d11 and just reinstall optiscaler and it should work fine

[molten wharf]

what should i install first, as some files are overwritten by other

[subtle plover]

theirs.

read my readme

it says it all

[molten wharf]

does it look good ?

[subtle plover]

shadow are broken

i don't think the mod is applied correctly

[subtle plover]

they are checkerboarded

This is the latest build btw.

[molten wharf]

i will try again

[ivory agate]

Yeah so Luma:ScenePeakWhite in ReShade.ini reflects what I set it to with the slider (i.e. 1500), but when I go back into game (after a game restart) the slider value resets back to 775.

[subtle plover]

try to set it to 1498 and boot the game

[ivory agate]

K, one sec.

[subtle plover]

and if you set it in game to 1600, will it be 1600 in the same ini? make sure of that too pls

[ivory agate]

OMG, I feel like an idiot, I had a feeling something was off.

It never used to say that. It always used to say 1,500 nits out of the box. Don't know what changed.

Looks like I'll have to use the HDR calibration tool to fix this.

[subtle plover]

told u 😛

775 sounds more likely than 1500 if it's an OLED monitor

1500 is the Windows default

it's often errounenously put there

also when u swap monitor

sometimes Windows breaks and shows 1500 even if u calibrated

[ivory agate]

It says 1,500 nits on the spec sheet for the TV, so I have no idea if that was what's going on, or the Windows default. Ugh.

Well whatever, mystery solved.

[subtle plover]

calibrate and see

[molten wharf]

most likely due to engine.pak, although it's mentioned in instruction, but i am not understanding clearly which one to use🙏

[molten wharf]

i followed every step

[subtle plover]

What's ambiguous about it?

[molten wharf]

#1262582420239286372 message

Does it look ok

[subtle plover]

If the sliders work it should be OK.

The mod doesn't even need the other files beside shaders.

No idea how you could even get it to not fix the broken shadow.

[rough harness]

Hi guys. I just wanted to play Prey (for the first time), installed latest alpha version of Luma from here + PREY Enhanced Mod + Shuttle Bay Fix + TOUCH-UP MOD.
I have 5800X3D CPU + 7900 XTX GPU, but the performance is very low. In one of the first rooms where is the helicopter simulation, I even have under 50 FPS when looking on the PC screen. But GPU usage is very low (56%, VRAM 33%). CPU is not limiting nor RAM.
Is this normal?

[subtle plover]

the readme explains what settings take the most performance.

[rough harness]

I'm looking into the readme but I don't see it here :/

[subtle plover]

advanced settings, lower or disable ambient occlusion and SSR

[rough harness]

I already tried to play with the settings, but it doesn't affect FPS. Setting SSAO to 0 lower GPU usage from 55% to 50%, but FPS are still the same. Changing SSR doesn't have big effect. I tried to disable all post processing, again no change in FPS.
When I tried to change in-game setting from very high to high, there is some FPS lift, but pretty low and still low GPU usage :/

I will try tomorrow vanilla game.

The mod otherwise looks working fine. HDR is working, switching e.g. FOV fix is also working.

[subtle plover]

GPU usage doesn't mean much. Maybe one thing is still bottlenecked within the GPU.

Try running in windowed at a lower res, see if the FPS goes up

[rough harness]

switched from full screen to window borderless and lowered resolution (from 3440x1440 to 2560x1080).
FPS are still the same (around 47), only GPU usage lowered to around 40% :/
I restarted the game for sure after changing the settings.
I'm going to bed now, I will try to test more tomorrow.
Thanks!

[subtle plover]

sounds wrong. I dunno. try without the other mods.

[wintry kestrel]

Seems to be a known issue. If you scroll up the thread you will see a bunch of people including myself with similar peformance issues. All seems like we have an AMD GPU and an 5X00X3D cpu.

[subtle plover]

yeah, i'd need somebody able to compile code to test it properly

I do not have an AMD GPU.

There's nothing Nvidia specific about the mod, beside DLSS which can be turned off.

[tender osprey]

there is something wrong with the mod but we don't know why. you can see my testing here #1262582420239286372 message

the only thing we know for sure is that it affect people with an AMD CPU and GPU (IMO it has mostly to do with the GPU)

[subtle plover]

I could really use somebody maybe building the code and trying out a couple different things

I can't do anything without an AMD GPU unfortunately

[valid kiln]

the issues happen on intel gpu too, i don't think its related exclusively to amd gpu, but maybe amd cpu ?

[subtle plover]

CPU likely affect this less than GPU. That said, it could be.

[rough harness]

Thanks for replies
I tried to play with the settings in game and changing FOV changes the FPS proportionally. When I changed the FOV from 120 to 60, I got around double FPS.

[subtle plover]

cool. could you post a video of that happening live?

that would imply that the performance is butchered by the amount of draw calls.

the more objects on screen, the more draw calls.

ReShade adds a fair amount of overhead for draw calls, Luma adds its own on top.

if you look at the floor, performance goes high a lot too?

[rough harness]

I will try to fire up OBS 😄

[rough harness]

not the best quality, but FPS counter is readable.
140FPS is max FPS (limited now by RivaTuner)

[subtle plover]

Jesus what is that quality 😄

do u see the shadow blocky/pixellated as in the left screenshot?

seems like a draw calls bottleneck to me

[subtle plover]

can you build from source code?

[rough harness]

yeap, I have this pixalated shadows.
I will try to setup and build from the source code, it will just take me some time, with 5m old children it's worse with a free time XD

[subtle plover]

that means the mod hasn't applied correctly

maybe it's slow cuz it's literally spamming errors every frame

did you check the log?

for Epic store, the shaders need to be put in different folders.

probably that's what @molten wharf had gotten wrong at first too?

[rough harness]

The log you mean the one directly in the ReShade?
I followed the readMe installation instructions. I have Epic version and I renamed the folder.
As first I installed ChairLoader and Touch-Up mod. After that I copied the Luma

[subtle plover]

the same one he posted above, yes

in the game exe folder

[rough harness]

I don't see any errors, but lot of warning like TheHuntRider about loading CustomShader

[subtle plover]

that's it then...

CPU usage is low, GPU usage is low

the bottleneck is the log being written on disk

every frame

[subtle plover]

is it on SSD?

[rough harness]

Yeap, 970 Evo 1TB nvme

[subtle plover]

can u check if these LoadCustomShaders(Unknown hash: 0x0a210c5d) print every frame

or just in some particular moments?

u can see the log from within ReShade interface too, in game.

Log tab.

[rough harness]

it generates only when I move, when I stand still (or even do only slight move by mouse) it doesn't generate.
So it's not really the problem of the low FPS, but it's probably problem, why movement in the game is pretty choppy and frametime is very inconsistent

BTW in chairloader I just got errors:
[Error] CLoaderCGF::LoadCompiledMeshChunk: Bad geometric mean face area. File [objects/characters/aliens/mimic/mimic01_lod2.skinm] Chunk [Mimic01]

[subtle plover]

that's a bug with the game, movement is inconsistent

[subtle plover]

Nevertheless, shadow are broken so something is off

I will try it

[rough harness]

For sure I tried to fully delete the game and start over.
With vanilla game, I have smooth 140 FPS (my limit) with 65% of GPU usage. Movement is smooth, frame times are flat.
Then installed reshade (no change in performance), then I installed the v3 alpha 1 Luma (without any other modes).
In the first room 60 FPS with 60% GPU usage.
I also noticed that after installing Luma, the game starts to use "standard" folder for save games (Saved Games\Arkane Studios\Prey). Epic use by default Saved Games\Arkane Studios\Prey_Epic.
but I don't think it should be a problem

The shadow now looks ok, so maybe the pixalated shadow is connected with other mods:

I also noticed that the low performance is already in intros and menu.

[subtle plover]

try re-installing the other mods now

[wintry kestrel]

Has anyone been able to disable reshade logging as a potential fix. I've tried [INSTALL]
EnableLogging=0 and doesnt seem to work

Was able to disable logging with
[INSTALL]
Logging=0
but made no impact on performance. No reshade.log was generated.

[subtle plover]

Do you have pixellated shadows?

[wintry kestrel]

Not that I have noticed in gameplay but will have another look. I'm getting the Custom shader warning and same behaviour of looking at the floor get max FPS and then looking in a direction with lots of objects it drops (i.e crew quarters from the stair case). Dynamic Res kicks in dropping the resolution to about half but no change in FPS then if dynamice Res off

[subtle plover]

No change in fps if dynamic res is off? So dynamic res makes it slower?

Dynamic res is broken in prey, it should be avoided.

[wintry kestrel]

No sorry I mean dynamice res enabled on the mod performs the same as dynamic Res disabled on the mod in terms of FPS for me

[subtle plover]

So it's not a cpu problem if the resolution going down brings performance back up.

[wintry kestrel]

Nah so the resolution going down does not increase the performance

It stays the same

So my thought is that it is a non GPU bottleneck (I e CPU)

Since despite it going down to like 540p, the FPS stays the same as if it hadn't decreased the resolution

[subtle plover]

Yeah ok. Makes sense.

I have a couple of ideas but I will need a lot of help.

I could send builds with features disabled and then you tell me which one is faster.

[wintry kestrel]

Yea I'd love to help out however I can! Just send me whatever and I'll test it out. I'm guessing you aren't having issues on your setup haha

[subtle plover]

The only reports I got are from amd users.

[wintry kestrel]

We are needy

[wintry kestrel]

Also don't know how much this helps but with Luma addon disabled in Reshade, but everything else installed as per mod instructions, the FPS behaves as expected so would seem to be something in Luma-Prey.addon

[subtle plover]

Reshade only enables the addon feature if at least one addon does anything

Try to drop in there the generic renodx unreal addon and see if performance is crap too

[celest jewel]

disable generic depth and effect runtime sync addons if you haven't already

[wintry kestrel]

Yea put in the generic unreal addon. Performance is not crap and same as vanilla Prey(2017). Am even able adjust game brightness and peak brightness (although peak does seem capped)

[wintry kestrel]

Yea both disabled

[subtle plover]

Yeah because it's sdr 😅

Good to know.

I'll send some tests next week.

[wicked mural]

I have so many flickers with this mod installed. Like windows in the distance will freak out and lighting/shading will just not load in, in certain area making everything look cartoony

[subtle plover]

It happens in the vanilla game anyway

[wicked mural]

Not that I've noticed

[subtle plover]

Try the same place with and without the mod. Post a video if they are different. Thanks.

[acoustic sapphire]

Is there a way to save the advanced settings without reloading shaders? Reloading shaders seems to hard crash me every time running on Linux.

Also - can I clear the Luma shader cache outside of the game?

Am trying to see what might cause highlight flicker with the Lossless Scaling Linux port when using Luma, but cant save any changes on advanced settings atm

[subtle plover]

You can clear the shader cache.

Reloading shaders shouldn't cause crashes.

I'd like to investigate why.

[acoustic sapphire]

Im guessing it's probably a Linux specific problem

Does Luma write a log? I'll try pass one along tomorrow.

Mod looks epic BTW, so great to have HDR in one of my favorite games

[subtle plover]

Reshade does yes. Exe folder.

[acoustic sapphire]

okay so for some reason, after quite a few days of crashing every time I attempt to reload shaders, its not doing it anymore 😄 seems to be working fine.

the only issue I have now is that once HDR is activated, if Lossless Scaling framegen is used highlights all tend to flicker like crazy. It's odd cause I don't see any issue with HDR in other games/HDR mods. But the problem might be in LSFG itself

[subtle plover]

Probably doesn't support scRGB HDR.

[acoustic sapphire]

Thanks, I will chat to the dev about it

[acoustic sapphire]

Do you think this would still be the case if the flickering happens even when Luma is set to SDR mode?

[subtle plover]

Yes it's still hdr

[acoustic sapphire]

Ok cool, thanks, I think you found the smoking gun. Another user on the LSFG discord complained about flickering in another game that uses scRGB

Thankfully I dont need FG to enjoy Prey since it doesn't run like dogshit, thanks again for the mod 🚀

[forest tinsel]

i'm new to reshade and wanted to ask is this the correct just the luma one checked not the default reshade preset ?

also now the game look yellowish is it supposed to look like that ?

[subtle plover]

Seems Ok to me.
You don't need any reshade effects, they are a separate thing.

[flint palm]

My game is all red like this,I had the epic version installed before but read that the mod is not compatible so now I have the GOG version. Is it a shader problem or something?

[subtle plover]

#1262582420239286372 message
This version is compatible with the epic store.
Regarding the red on the gog version, it seems like the mod just isn't installed properly.

[flint palm]

I used vortex and files are correctly applied. Guess I will try again with the epic version. I thought it was a problem with the shaders or something.

Oh nevermind I wrote that already. I will just try anew

[subtle plover]

Don't use vortex

[flint palm]

Okay maybe that's the problem. One more thing, would you recommend using the real lights mod also or is that redundant?

[subtle plover]

It's in the readme docs

[flint palm]

So I tried multiple times with reinstall of Epic and GOG and did excactly like in the readme, but I still get this red like in the screenshot. Everything seems to work fine I can use reshade and the options menu. No idea what the problem is.

Didnt use vortex either this time

[flint palm]

sorry to bother you. The red error thing is not actually connected to the mod it seems. I even get that on a fresh install, no idea why

[subtle plover]

Dunno. GPU driver. Broken GPU. Can't help.

[flint palm]

this is the only game that does this. I will try to update GPU driver

[cyan ledge]

Interesting. Just recently I head the same issue with Dishonored when forcing 16x anisotropic filtering trough DXVK, if not forcing it the issue doesn't occur. Also when forcing 16x anisotropic filtering trough Nvidia CP in DX9 the issue does not occur.

[flint palm]

Yes I had it forced in control panel and that was the issue for me. Only with this game though.

[wild meadow]

Just installed the Luma mod for Prey and reshade shows that it's loaded. However, I'm trying to use it on an AMD 9070XT so need optiscaler but reshade fails to load when I install optiscaler. Any ideas?

[wintry kestrel]

Worst case you can use the mod without optiscaler. Will use TAA. What name are you using for the Optiscaler DLL when you install it? Standard practice is to have reshade stay as dxgi.dll and have Optiscaler as something different ie dsound.dll. when you install Optiscaler through the .bat file should be a bunch of options just make sure it isn't install as dxgi

[wild meadow]

Managed to get them both working together by renaming dxgi.dll to Reshade64.dll and Opti as winmm.dll. Had to also edit the optiscaler.ini to make it load reshade64.dll.

[subtle plover]

Luma: Prey (2017)

[subtle plover]

New version coming soon.
Shaders compilation wasn't using optimization and that might have affected performance.
c++ compilation also wasn't optimized as it could.
There was a mistake in the DICE tonemapper that made highlights shift in hue.

[valid kiln]

can't wait to test it

[subtle plover]

can u build code?

[valid kiln]

nope sadly no, sorry

[subtle plover]

did u say performance isn't fixed if u unload shaders?

[valid kiln]

yes i think the last time I tested it, you told me to do that it didnt fixes anything

I don't remember which GPU I was using, but in the meantime I switched from amd to intel, yet the performance issues persisted (same cpu ryzen 5600)

[subtle plover]

you switched GPU?

[subtle plover]

Can u try to delete the Luma shaders folder and run the game?

[valid kiln]

that ?

[subtle plover]

yes

do you not have .cso files?

[valid kiln]

i have

i delete everything ? even the folders ?

[subtle plover]

move it somewhere else completely yes

[valid kiln]

ye i moved the "luma" folders

no i don't see any difference (I had to check several times)

[subtle plover]

so it runs like shit unless u are looking at the floor?

can you set all the game render quality settings (in the game itself) to the lowest?

[valid kiln]

yes the cursor position determines the fps, looking at the floor or the ceiling or in the opposite direction affects it quite a bit, the gpu usages stay very low at 35%

I test on low when the storm has passed

[subtle plover]

you mean the camera direction?

[valid kiln]

Yes

[subtle plover]

and without the mod, GPU usage goes how high?

[valid kiln]

I should check to be sure

It's been a long time since I played without Luma, but I remember it was highter lol

[valid kiln]

on low i get 20% more cpu usage and more fps

[subtle plover]

try this

[subtle plover]

but it's still shit?

[subtle plover]

this basically disables many of the mod hooks, if the performance is fixed, then I can narrow down where to look.

It won't load shaders, gamma might look off, but it doesn't matter.

[valid kiln]

well i get like 20 more fps so its a bit better

instead of 44 fps im getting like 70

[subtle plover]

what matters is the performance without the mod.

the mod should kill performance, especially if shaders aren't even loaded.

[valid kiln]

with luma shader or removed?

[subtle plover]

doesn't matter, it won't load them

try without first and then with

[valid kiln]

with luma folder - 90~99% gpu usage (very high preset)

[subtle plover]

and high enough frame rate?

[subtle plover]

make sure to disable adaptive resolution btw

[valid kiln]

oh yes

yes adaptative is off

im getting 120~190 fps (i deleted the image, i think they are not relevant)

[subtle plover]

ok

[subtle plover]

can you now try without the Luma addon

and then try without ReShade

and give me the performance for the same scene with and without each

THX!

[valid kiln]

ok

i keep the shaders right ? ?

And when you talk about performance, are you referring to GPU percentage or a capframex record?

[subtle plover]

fps

[valid kiln]

i made 3 capframex record

without luma is addon deleted

[subtle plover]

so the performance impact is from reshade?

[valid kiln]

i dont think, without luma or reshade its similar perf

i lose 50% perf with luma addon atleast on fps

[subtle plover]

ah yes, nevermind

[subtle plover]

and that was with the Luma addon I just sent you?

[valid kiln]

no with the v3 alpha from the pinned

i think with the lastest luma addon, i would have the same fps as without luma or without reshade

It would be very similar

i will record the fps

[cyan ledge]

Could be vsync issue. Check with Present Mon "Sync Interval" should be 0 after you turn it off in game.

[subtle plover]

ok so the new Luma addon fixes performance.
Even with the shaders in the Luma folder?

[valid kiln]

I think luma shaders was present, but I can only confirm it tomorrow

[subtle plover]

doesn't particularly matter

i can try give u a couple more builds for more tests

[valid kiln]

Why not You can send them tomorrow if you want, I could test them

[wintry kestrel]

With the above prey-luma.addon and 'V3 Alpha 1' base I get an error code:
4:53:55:603 [ 320] | ERROR | Failed to load add-on from 'Z:\home\jcd\Games\Heroic\Prey\Binaries\Danielle\x64-GOG\Release\Luma-Prey.addon' with error code 126!'.
If I use the prey-luma.addon from V3 Alpha no issue. Using pinned reshade

[wintry kestrel]

Tried on GOG on linux, GOG and Steam on Windows and same issue. 5700x3d RX 9070

[subtle plover]

You need the latest version of reshade for it

[wintry kestrel]

Pinned one from RenoDx channel?

Tested both the Pinned RenoDx one and also vanilla 6.5.1 with addon suppot and still the same issue

[subtle plover]

Install the latest c++ redist

[wintry kestrel]

Yea all up to date with no luck.

[cyan ledge]

DXGI_SWAP_CHAIN_FLAG_ALLOW_TEARING is being set for swapchain, but I cant see DXGI_PRESENT_ALLOW_TEARING being set in present as it should according to documentation and my tests. So I hooked present and added DXGI_PRESENT_ALLOW_TEARING, and now it works as expected and also it solves the FPS lock bug with low GPU usage.
Here is the minimal code example to implement this:

#include <MinHook.h>

// IDXGISwapChain::Present
typedef HRESULT(__stdcall *Present)(IDXGISwapChain* swapchain, UINT sync_interval, UINT flags);
static Present present = nullptr;

static HRESULT __stdcall detour_present(IDXGISwapChain* swapchain, UINT sync_interval, UINT flags)
{
    flags |= DXGI_PRESENT_ALLOW_TEARING;
    return present(swapchain, sync_interval, flags);
}

void OnInitSwapchain(reshade::api::swapchain* swapchain, bool resize)
{
    static bool hook_installed = false;
    if (!hook_installed) {
        auto native_swapchain = reinterpret_cast<IDXGISwapChain*>(swapchain->get_native());
        auto vtable = *reinterpret_cast<void***>(native_swapchain);

        // Try to hook IDXGISwapChain::Present
        present = reinterpret_cast<Present>(vtable[8]);
        if (MH_CreateHook(vtable[8], &detour_present, reinterpret_cast<void**>(&present)) == MH_OK && MH_EnableHook(vtable[8]) == MH_OK) {
            reshade::log::message(reshade::log::level::info, "Hooked IDXGISwapChain::Present");
            hook_installed = true;
        }

Interestingly if you force vsync off in Nvidia CP the game will act in the way as if DXGI_PRESENT_ALLOW_TEARING was set even when it isn't set.

[subtle plover]

yes, Nvidia does whatever it wants with these flags

which tbh are horribly named and documented anyway

[subtle plover]

looking into this. Thanks.
The answer is probably that the issue doesn't appear on NV.

[acoustic sapphire]

Going to try the recently shared addon, was just about to report a very strange 40 - 50% fps drop when looking at the elevator in the lobby

that wouldnt change no matter how I altered my settings (goes away if reshade/the addon isnt loaded)

I am on Linux through gamescope though, so I'm not sure if that has something to do with it, I suspected some kind of double buffering or something might be happening

getting the same issue as reported above with latest reshade: 17:26:46:142 [ 324] | ERROR | Failed to load add-on from 'Z:\var\home\bazzite.local\share\Steam\steamapps\common\Prey\Binaries\Danielle\x64\Release\Luma-Prey.addon' with error code 126!

Will try updating my redist now...

same issue unfortunately

Interestingly, going back to the v3 alpha without loading shaders still has the same perf drop

from 106 fps to 48-50

as soon as I look at the middle of the lobby...hmm

this sounds a lot like some kind of vsync issue

updating vc redist through proton tricks is causing my shaders not to load, so thats just a me issue, but its interesting that even though the shaders didnt load correctly, the perf drop is still there

how do I manually clear the shader cache? Weird issue since recreating the prefix:

[subtle plover]

https://github.com/crosire/reshade/pull/365

[subtle plover]

delete all .cso

[cyan ledge]

Nice work. Probably the best solution for this.

[acoustic sapphire]

Thanks! Do you think the drops I mentioned might be related to this vsync issue?

[acoustic sapphire]

Ok, very weird, not sure why but I can't get the addon to load even after reinstalling the game. This error every time. But I'm suspecting its something to do with the way the proton prefix is setup

[acoustic sapphire]

Okay, so when I use the most recent unofficial reshade build triggered by this PR,

The v3 alpha addon causes the "memory could not be "read"" error

The addon sent above fails to load with error code 126

is this potentially just a vcredist problem?

okay, wow, excuse my rambling.

it most definitely is - not sure if this might help other linux players, but installing vcredist through proton tricks UI wont work, the only way to get it working is to actually download it yourself and run the installer using the proton tricks commandline using Prey's prefix

sorry for spamming this channel! Maybe that will help someone.

[acoustic sapphire]

Okay so -

The version with hooks removed is still giving the 126 code error, but I can at least say that:

With reshade but no luma - looking at the lobby elevator, fps stays stable - 95
With reshade and luma - looking at the lobby elevator the fps drops by about 45 or so. 45-50

This is using the latest build triggered by your DXGI present flags PR.

GPU usage is hitting 100% in both scenarios.

Adaptive resolution down to 33% only improves the final fps by about 3 or 4

@subtle plover

Changing graphical sett8ngs doesn't affect it at all, and the Luma advanced settings are all at default

if it helps, CPU is 7800X3D and GPU is 7900XT

[subtle plover]

@acoustic sapphire @cyan ledge @wintry kestrel @valid kiln @rough harness @tender osprey
New version with proper VRR support, it might fix low frame rates.
Test pls. ReShade is included as I had to change a thing in it.

https://aka.ms/vs/17/release/vc_redist.x64.exe

[acoustic sapphire]

Sweet will test it now

[valid kiln]

Can can test in 2-3 hourd

[acoustic sapphire]

Okay so it defintiely feels smoother and the drops I reported in the lobby are less drastic. Tested borderless/fullscreen/vsync on and off, frame limit set at 165

I've narrowed down the lobby frame drop to a very specific concentration near the security booth and the bathrooms on the left hand side (when facing morgan's office)

Here are some screens

In the very first shot, fps has dropped down to a 45-52 range (the most drastic drop - from about 80fps average)

In the next 3 as I'm slowly turning it goes from 70ish down to about 50 as the flame particles and bathroom areas become more visible

If you want me to do some more detailed tests let me know, I know this seems quite anecdotal so I'd like to help more thoroughly if I can 😄

[subtle plover]

I just need to know whether the performance isn't randomly killed for seemengly no reason

looking at big rooms will slow down performance, the mod isnt' free

i just care about comparsisons without the mod.

[acoustic sapphire]

Further up the stairs its less drastic, near 60. Back in Morgan's office area its back at 85. Looking towards the back of the lobby and its back up to high 70s

[acoustic sapphire]

That's fair, sorry to potentially waste your time.

Without the addon enabled, even with all the other changes Luma makes, there's no differential in FPS walking around these rooms, its all basically locked.

I understand the mod isn't free but such a big jump feels slightly odd considering my rig, but maybe it's just a linux thing.

[subtle plover]

so compare to the performance with the previous pinned alpha

also, delete all the .cso files cuz the new version compiles them in a more optimized way

but only if they weren't there already

the others had clear CPU utilization problem

I don't know if this is it

[acoustic sapphire]

Ok cool will give it a try

[subtle plover]

so i guess the dll loading issues faded?

[acoustic sapphire]

Yeah, it was definitely a vcredist thing. Installing it through proton tricks just isnt good enough - the latest download from your link posted above is what solved it

Deleted all the .cso files, going to test again and then try the previously pinned alpha again and let you know

Performance is definitely better by about 4-5 fps in the new version and it feels smoother/better latency (at least to me) - especially after deleting the .cso files

However, I think perhaps the issue in the lobby is a red herring. Just did another uncapped test without luma and the drops are still there - the fps is just higher so I dont notice it so readily.

Thats 150 fps down to 110. Apologies @subtle plover I think in my previous test I had forgotton to turn off my fps cap/vsync

This is maybe just a game optimization issue but I suppose the only way to truly verify that would be to remove all the mods and do a true vanilla test

After deleting the .cso files, I dont seem to drop below 50 fps in the same situation, so way more manageable. I take it the difference otherwise is just a consequence of adding new shaders and remastering to the game's pipeline - like you said, its not free

This really does feel like Prey remastered though, thanks for all your hard work on this. Just having better shadows and AO is a game changer alone but HDR truly takes this game to the next level

[cyan ledge]

Tested, looks good.

[valid kiln]

your camera position with 50 fps loss is heavy yes, its normal

[wintry kestrel]

I still seem to be having utilization issues with my setup. Luma addon loaded, 80fps in crew quarters with low utilisation. Addon not loaded, 203fps with maximum gpu utilisation.

[valid kiln]

i just checked and the gpu usage stay lows

feel a bit smoother i won't lie

What I mean is that the camera movement seems smoother with the variation in fps, but maybe it's just a placebo effect

(i chcked if the game has vsync, its disabled ; checked with but nothing changes)

[subtle plover]

Did u delete the cso files?

[valid kiln]

yes i reinstalled the whole game

[subtle plover]

Ok. Did you try with the latest addon but with shaders removed?

[valid kiln]

no, i remove the whole luma folder?

this one "Luma"?

[subtle plover]

Try this (still use the reshade version from above)

there's a slider in the settings

Disable Features

set it to 1 and 2 to disable more features

and tell me when the frame rate increases or decreases

thx

[valid kiln]

with shaders?

[subtle plover]

yes

[valid kiln]

1&2 gives me black screen ,thats normal right ?

Otherwise, there is no difference between the two, except for the black screen

Maybe i should remove all cso?

no effect

[subtle plover]

ok, just look at the performance then.

still bad performance?

[valid kiln]

yes nothing changes

[subtle plover]

well then I have no clue

I've literally disabled the main features

nothing else is going on

[valid kiln]

idk either

[subtle plover]

try this, empty addon

delete the Prey one.

it might look off, ignore that.

[subtle plover]

did you try lowering the post process quality in Prey Luma settings?

[valid kiln]

gpu usage (70%~)is still lower than without luma but the fps is way better with empty addon but less than vanilla

[valid kiln]

Can try

witch one ?

[subtle plover]

It's in the main settings. Not advanced.

[valid kiln]

nope perf still slow

[subtle plover]

You need to change resolution at least once

[subtle plover]

I'll send a couple more empty add-ons later.

[blissful bison]

Hey I managed to get optiscaler running with fsr but trying to swap to xess crashes the game with this error message every time, no other mods installed

[blissful bison]

the game also runs fairly poorly with the mod installed, about 50% gpu usage

[subtle plover]

That's under investigation

[subtle plover]

Clean the game settings files

[valid kiln]

you need the optiscaler nightly build for xess and if you are not on intel gpu, use xess w/dx12

[blissful bison]

I am using the latest nightly build and I actually am on an intel gpu

[valid kiln]

OptiScaler_v0.7.7-pre13_20250728 that version ?

[blissful bison]

yea

[lunar remnant]

no idea if related to this or not - but i think one or two DF Directs ago, Alex mentioned that he thinks he's found a performance bug in X3D chips but he is doing further testing and talking to AMD before presenting it/making a video about it

[valid kiln]

not related at all, i own a 5600

[acoustic sapphire]

Okay, I'm glad at least that it's not just me with this very strange performance drop

This mod is incredible as it is, I'm sure its a fixable problem but having a blast playing the game with this as it is 😺

[subtle plover]

I'll fix it.
We also have an issue with the weapon fov resetting every time a level loads, which prevents the perspective correction from being usable.

There's a few things left before the mod is 100% finished.

[acoustic sapphire]

The Perspective Correction is such a cool feature

Was adding it inspired by the Looking Glass screens? @subtle plover 😄

[subtle plover]

No. It's just the future of rendering imo.

[acoustic sapphire]

I definitely see why you think that. Feels a lot more like you're actually there

Which in a game where immersion is so important, is amazing

[acoustic sapphire]

It looks like the fps drop in the lobby slowly starts to get worse over the playthrough. When I came back now and a bunch of new typhon spawned, In some spots I am dropping from 90fps to 43fps, but it seems very inconsistent

But again that's probably just a base game optimization issue, and the other lower fps issue in the mod is just making it more noticeable.

[acoustic sapphire]

Arboretum is another heavy one. 95fps down to 38-40 depending on the viewing angle.

I suspect in vanilla this would be like a 150fps down to 100 fps drop (optimization issue in the level itself maybe) but the other performance problems just exacerbate it.

My GPU usage levels seem fine though.

[subtle plover]

trying now

[acoustic sapphire]

@subtle plover Okay so stopped being lazy and added MangoHud overlay. When I look past the elevators in the arboretum the gpu usage drops by 20-30 percent and the fps by 40 - 50 %

If I enable some of the more expensive luma settings - like extreme SSR and GTAO, the GPU usage actually gets better, avg and maximum fps goes down, but the minimum fps goes up

The moment I get behind this cargo box to the right, the fps will tank. The FPS starts steadily climbing as I walk past the wall on the right towards the fountains

[acoustic sapphire]

I'm not so clued up on how hardware usage is supposed to behave in situations like this. The GPU usage going lower i understand is a bad thing - but is it normal for a 7800X3D to be sitting at 30 percent usage in a situation like this? The GPU is a 7900XT

[subtle plover]

the problem has been identified

it's the cbuffers mapping in the CPU

i'll try to optimize it

[valid kiln]

[acoustic sapphire]

🚀 🚀 🚀

[subtle plover]

I've improved the CPU bottlenecking in these locations by about 50%

ultimately it's due to a reshade "limitation"

ReShade abstracts DX data to a generic format to work with Vulkan and OpenGL too etc

so data is converted 3 times every time stuff is done

when there's a lot of draw calls, that's a huge overhead on weak CPUs.

the cost is fixed per object on screen, independently of the resolution.

I've optimized:

• Custom Pixel/Compute shader detection
• Custom Texture Samplers detection
• Global CBuffers detection

biggest bottleneck is the samplers.

[acoustic sapphire]

You absolute legend!!! Thanks for your hard work.🤘

So that explains why it was always those specific angles. Happened to be the angles where the most objects appeared on screen at once

And maybe when the game isn't occlusion culling super effectively (does it even occlusion cull?) Its more noticeable

[subtle plover]

r u 100% sure this did anything?

[cyan ledge]

Yes. Also can reproduce same issue in other dx11 app. It also solved for me the strange FPS lock to multiple of screen refresh rate if FPS would drop close to that number.

*multiple: so /2, /3, etc.

[subtle plover]

@acoustic sapphire @cyan ledge @wintry kestrel @valid kiln @rough harness
test this new build.
Replace the DICE shader in Luma\Includes for a quality fix too, highlights color hues were accidentally shifted

[acoustic sapphire]

Sweet will do 😁

[acoustic sapphire]

Do I need to do anything specific after installing the new build? Tried recompiling shaders but it looks like the issue might have actually gotten worse:

I was able to at least maintain about 38 - 40 fps in the worst bits, but now its averaging around 27 and dropping to 16 🤔 GPU usage also low

[subtle plover]

Test again with the previous addon I upload some days ago

[acoustic sapphire]

Ok, will try

[acoustic sapphire]

this one?

ah wait no you probably mean the one with the added VRR support

testing now.

The max is a teeny bit better (also excuse the clipped highlights I have to use snipping tool to get mango hud in screenshots)

Going to just see what happens if I use the old reshade build you shared too to make sure its not some kind of weird issue on my end.

So it looks like whatever changed in the reshade assembly is what is busting things, this is reshade + build from a few days ago. Going to try latest build + reshade from a few days ago, see what happens...standby

[valid kiln]

i will give a try

[acoustic sapphire]

Okay no, looks like both builds (reshade + addon) wreak havoc in some strange way, since using just the addon I'm back to 30fps dropping to 16

let me know if you want me to try any more tests, I'm sure this nut is close to being cracked 🚀

[valid kiln]

[subtle plover]

Sorry, could you make a diagram or something. I'm not sure.

[acoustic sapphire]

Lol, I need to figure out how to get mango hud to export those cool benchmark diagrams that people make, but otherwise here's a basic summary (excuse the AI using emojis, always annoys me)

I think what's odd is that in my situation I have a pretty strong CPU, so maybe there's something else causing these bottlenecks? I would think it would at least try and brute force through the overhead, but maybe thats what the older build was doing (although the usage is low on the CPU side regardless)

[subtle plover]

Older build from some days ago, or months?

[acoustic sapphire]

Some days ago, this one:

[subtle plover]

Ok. I've probably attached a reshade debug build.

Accidentally

[acoustic sapphire]

Ahhhhhhh

[subtle plover]

Reflections in mirrors are almost entirely blacked out with a weird reflective doubling effect at the edge if you look at the mirror while at an angle. There's also a slight ghosting effect on weapons when moving.

Can anybody reproduce this problem too?

[valid kiln]

Sadly no, game is blocked at launch

[acoustic sapphire]

I havent experienced that issue, no.

[cyan ledge]

Probably, the file size is big and CPU usage is much higher. Other than that looked good, didn' t notice issues with mirror. Also 'Luma/Shaders/Include'? mine are all in 'Luma' folder ofc in subfolders too eg. 'Include'. Did I incorrectly setup this, cause I'm not getting errors?

[subtle plover]

only one file by that name. replace that

[cyan ledge]

Looked into v3a, same folder structure that I had. Looks good to me.

Noticed error with IMGUI.

[subtle plover]

@cyan ledge @acoustic sapphire @valid kiln should be good now

[subtle plover]

they are stupid errors, it's totally fine.

[cyan ledge]

Tested, looks good.

[valid kiln]

hm the game run but the perf are worse

[subtle plover]

with this one?
#1262582420239286372 message

[valid kiln]

Yes

[subtle plover]

i don't understand.. it runs very well for me.

[wintry kestrel]

Yea sam performance drop for me with the newest files

[valid kiln]

but i think it improved on stutter, i think the game doesn't stutter

whereas before the game had stutters here game is "smooth" at 30fps 😅

[wintry kestrel]

I don't know if this matters at all but the folder path for the DICE shader on the pinned version is 'Luma\Includes' instead of 'Luma\Shaders\Includes'

I hope that could be why performance is different is that something is different behind the scenes haha

[subtle plover]

in a busy view, I get from 65 fps to 48 fps. Nowhere as bad as this

[acoustic sapphire]

Will give a test in a bit 🚀

[acoustic sapphire]

Same issue with these

[acoustic sapphire]

Is it possible that the added validations might have accidentally added more overhead? Unless it's actually performing better than it was before on your side, and there's something else happening here

[acoustic sapphire]

Ah, yeah you said here its running well for you. Then it must be something else happening!

[subtle plover]

Validation?

[acoustic sapphire]

Ignore me lol, I obviously have no idea what I'm talking about with this stuff. The detection changes you made, I just wondered if maybe it added overhead by accident, but seeing as I know next to nothing about how buffers and graphics programming works, I'm sure that's wrong. I was just checking the latest commits on the repo and wondering aloud.

If you want me to test again just let me know 🫡

[valid kiln]

could it be related to the prey version we own ? i only own the base game

out of curiosity, what is your cpu pumbo ?

[subtle plover]

not even that gr8

gotta build a new PC

https://tenor.com/view/bed-time-gif-21640936

[valid kiln]

[acoustic sapphire]

What CPU do you have?

[valid kiln]

5600

i wonder if its the prey version that might matter

[acoustic sapphire]

So we all have ryzen cpus, but looks like Pumbo's is behaving

[valid kiln]

you have the deluxe or the base game ?

[acoustic sapphire]

Maybe. I am on the steam version with the dlc. Im also playing on Linux though, through Proton, so maybe that affects things too

[valid kiln]

yeah no , our problem is not that

[acoustic sapphire]

I'm having so much fun with this game despite the performance problems though. Soooo cool what you can do with all the abilities

[subtle plover]

@acoustic sapphire @valid kiln

i had probably uploaded a debug build again, accidentally (first time for ReShade, second time for Luma)

if it's still slow, u will see a Disable Feature slider in Imgui.

try all values from 1 to 11 and tell me which one restores the frame rate to the highest level.

[valid kiln]

ok trying

1,5 go for 99%gpu usage

6 has a little impact and go up to 50%

when 0 is at 20%~30%

rest feature stay at 20~30%

hope that help

[acoustic sapphire]

OK cool, testing now!

[subtle plover]

but is the performance by default as bad as in the previous build I had released?

[subtle plover]

I thought it was 2 and 4 for me that make performance better.

[valid kiln]

yeah

perf by defaut is worse than the prey version from the pinned msg

[acoustic sapphire]

I'll take some mango hud screenshots in a sec with load/fps for each mode, but yeah, perf by default is still a lot worse, around 51fps vs 95

[acoustic sapphire]

I should be using this dxgi, yeah?

[subtle plover]

yes

[acoustic sapphire]

Incoming screenshot spam, all in the lobby, one low complexity scene and one high complexity for each mode, open the shot to see the mango hud overlay top left (FPS capped to 60)

default:

Wait, let me retake these screenshots so its easier to read lol

1: Big gains, minimal drop

2: Same as default basically, but the max is higher

3: Same as 2

4: Same as 3 and 2 mostly

5: Same situation as 1, big improvements

6: Similar situation to the previous alpha build, but the drops are less drastic.

7: Same problem as 2/3

8: more of the same

9: more of the same

10: More of the same

11: More of the same

@subtle plover so it looks like mode 1 and 5 seem to restore the performance. Does that have something to do with TAA?

If I uncap my fps in those modes, the lowest I go is 60 fps or so.

[valid kiln]

6 also restore it by half

I'm more curious to know what the 6 does, rather than the 1 and 5

[acoustic sapphire]

Yes!

I can confirm that the same results happen in the Arboretum.

Okay definitely not TAA lol, since disabling AA does nothing. Only reason I ask is there are a lot more jaggies + shimmering in mode 1 and 5

(also, with AA off, 1 and 5 still increase performance massively)

[subtle plover]

ok so 1 and 5 determine the decoding of cbuffers

[acoustic sapphire]

🤔 the plot thickens

[subtle plover]

it's this function

it seems like it's particularly slow on some CPUs

[valid kiln]

what 6 do and why it boost to 50% gpu usage?

[subtle plover]

6 still does the check in the screenshot above, but then discards the result after

so given that 5 boosts performance but 6 doesn't as much

the slow function seems to be the one from the screenshot

[subtle plover]

@valid kiln @acoustic sapphire try this

i've optimized it

[valid kiln]

stil low gpu usage at default

i think it improved a little, the gpu is at 36% but not totaly sure fps is highter than before

instead of 20~30

[subtle plover]

try the sliders now

[valid kiln]

1&5 is still giving 99% gpu and 6 is giving 80~84%

yes 6 is almost perfct

this is 1&5

this is 6

6 improved

[subtle plover]

does your CPU have very little cache?

[valid kiln]

its a ryzen 5600

dunno

[acoustic sapphire]

I'll give it a test in a sec!

7800X3d has a pretty large cache, so hopefully this helps

[acoustic sapphire]

I was wondering if it was that! But wasn't sure if I could add anything helpful to the discussion once I saw it cause I don't know graphics programming.

Does that fire once per frame or per object being rendered?

[valid kiln]

if intel could make his ultra 235f 120€... would buy it

L1 Cache
384 KB
L2 Cache
3 MB
L3 Cache
32 MB
for the 5600

[acoustic sapphire]

I wonder if some kind of caching would help there, but seeing as it's a static method that might be tricky

[subtle plover]

@acoustic sapphire @valid kiln try this

[acoustic sapphire]

This is the cache on the 7800x3d

[acoustic sapphire]

Sweet just got to my PC will try now

[acoustic sapphire]

Same issue until 1 or 5

[valid kiln]

yea

[subtle plover]

wait. made a mistake

@acoustic sapphire @valid kiln

risky changes on DLSS/TAA

check if it's all looking good

[acoustic sapphire]

Cool, testing now 🫡

[subtle plover]

this will skip almost all tests.

[acoustic sapphire]

@subtle plover Looking good.

[subtle plover]

better than ever?

[acoustic sapphire]

This is the best the mod has performed since I first tried it 🚀 will removing those tests break things? Just going to run around and verify the TAA looks good (am injecting FSR3)

[subtle plover]

thing is, i play at 7680x2160 so the GPU is the bottleneck

CPU doesn't affect the fps

[subtle plover]

i will test.

[acoustic sapphire]

Looking good at the moment

[acoustic sapphire]

Riiight, this would explain why it never really cropped up before. I expect if I played at 5k instead of 2k ultrawide, it would be a similar situation.

[acoustic sapphire]

Thanks so much for your extremely hard work on this, I salute you sir 🫡

[acoustic sapphire]

Okay, shite, it looks like loading my latest save in hardware labs, its happening again, but at a higher fps:

Enabling mode 1 fixes again. But the global cbuffer tests are still at 0 as expected, so maybe the problem is half solved?

so the decoding of the cbuffers maybe still has an impact?

[subtle plover]

show me this menu

the values printed there

it should be 0

[acoustic sapphire]

ok cool, one sec

[valid kiln]

wait

[acoustic sapphire]

Okay hang on, I restarted the game and its performing well again?

Let me just see what happens if I load a different save, then reload this save

When I load a different save, it comes back @subtle plover

but the tests all still say 0

[valid kiln]

Ok

i found something strange

from features 0 to 6 to 0 fixe the gpu usage issues

[acoustic sapphire]

@subtle plover @valid kiln same here if I toggle 0 to 6, the issue on save reload disappears

[valid kiln]

these are the performance i get

when i switch 0 to 6 to 0

[acoustic sapphire]

yeah, 0 to 6 and back to 0

Could be a placebo, and something else is happening. Cause when I do that, stuff in the distance looks shimmery

yeah, after full game reload, the image looks more stable.

[valid kiln]

[acoustic sapphire]

For the global cbuffers, would something like static variable caching in the method help?

Like,

static const void last_valid_pointer
static bool last_result

if (last_valid_pointer == global_buffer_data_ptr)
return last_result

I suppose that would only really make a difference in a situation where the same pointer is evaluated multiple times, and I dont know how that works 😄

[subtle plover]

that's kinda what i did

[acoustic sapphire]

Ahh okay cool 🚀

Now to just figure out why loading into a new level changes it

[subtle plover]

try again. did it fail again?

[acoustic sapphire]

Yeah, if I load into the game fresh, it works well. But once I go through a loading screen the issue comes back, will do one more test

[subtle plover]

try this

[acoustic sapphire]

Load in - back into lobby - back into hardware labs

[acoustic sapphire]

testing now

[subtle plover]

the number in the imgui is still 0

so it's not the same issue

could just be the game has memory leaks

try the sliders, if any make you gain back performance when loading the second time into a level (try all)

[acoustic sapphire]

Ok cool, yeah no change with the latest result, let me just play with the sliders quick

second is after going 0 - level 6 - back to 0 - third is the resultant image looking a bit unstable for some reason

hard to show in an image, but even though that trick works, the final image is shaky and a bit wobbly, like TAA isnt working properly or something @subtle plover

[subtle plover]

obviously, it disables features, so rendering will break 😄

[acoustic sapphire]

No I mean, the rendering still looks a bit broken once back at 0 😄

[subtle plover]

ok, then i added some bugs

i'll test myself

[subtle plover]

can u check if performance goes lower when you load into that save twice with the last public release?

[acoustic sapphire]

Ok cool, thank you sir, for now I can just restart the game once through a load screen 🚀

[acoustic sapphire]

sure, the pinned alpha?

cool one sec

[subtle plover]

*old reshade

[acoustic sapphire]

ok cool

I can just grab the dxgi.dll from the last reshade build before the vrr pull request right

faster than running the installer lol

old reshade + public build. Looks like the loading other saves/moving between levels issue is not present, but obviously performance in the lobby area suffered. The performance in the hardware labs matches the latest test build when loading the save for the first time @subtle plover

[subtle plover]

on first boot, the new build is more performant or the same as the old?

[acoustic sapphire]

More performant, CPU usage is up by 5% or so and GPU usage around the same, but the max fps is a little bit higher

[subtle plover]

might have fixed the TAA bug and further improved performance

[acoustic sapphire]

Sweet I shall test now

Weird, the performance issue is back. Switching to 1 or 6 solves it, but 5 and switching back to 0, still low usage and fps

@subtle plover

whereas before 5 had the same performance as 1, and 6 was about halfway there

let me just see if there is a difference when i change levels

No difference between loading screens

[subtle plover]

wtf

[subtle plover]

did u try 7?

if 6 is slow but 7 is not, then it's the next function...
the function to extract data from the global cbuffer.

[acoustic sapphire]

I actually didn't try 7 - away from my PC now but will try as soon as I get back. 6 was as fast as 1 though

[subtle plover]

6 vs 7 is key, need to know. thanks.

[acoustic sapphire]

Cool I will test now

6:

7:

Definitely gets slower again when 7 is selected @subtle plover

so slowdown occurs on every level except for 1 and 6

(tested the rest now too)

[subtle plover]

ok then I understand

it's a CPU cache problem

i used to make a copy of the data in a pointer stored far away

I skipped that step in recent builds as the extra copy seemed unnecessary

but without it, the CPU probably overworks the cache

[acoustic sapphire]

Hell yeah, that at least narrows it down 💯

I am probably going to go to bed soon, but once I wake up, if you have anything you need tested I'll hop right in

[subtle plover]

*you can skip this one

[subtle plover]

and this, should be even better.

and then try this, it might be better than the last above or worse. hard to tell, depends on CPU cache.

[acoustic sapphire]

For this one: Hardware labs and lobby. Persisted across multiple save loads. Lobby performance is a bit worse than the pinned alpha build. FPS increases by up to 50% on level 1, but no changes on any of the others. Going to test latest one now (couldnt sleep lol)

[subtle plover]

ok, try the disable feature slider too

[acoustic sapphire]

A bit worse than the first one, but the disable feature level 1 has the same effect (up to 50% increase in fps) none of the other features affect it

[acoustic sapphire]

Did for both, only slide level 1 affects the fps, but it does increase it by a lot, 20 fps in hardware labs and 30fps or so in lobby

for both of them, save loads didnt change the output

so that issue is definitely gone

[wintry kestrel]

This with disable feature set to 1 seems to be my best performance version. Close to native. 5700x3d

[acoustic sapphire]

Yeah, 1 has a MASSIVE effect

[wintry kestrel]

All others seem similar performance to you aswell?

[acoustic sapphire]

yes, 1 is the only one that changes it now, which is good i think, probably narrows it down for Pumbo 🫡

The version with the tests bypassed is the best performing version out of all of them, UNTIL you move between levels, but I am not sure if that bug was related

[acoustic sapphire]

this one, basically

and im guessing level 1 is the bypass? or global cbuffers

[subtle plover]

so 5 to 7 didn't improve performance with these?

[wintry kestrel]

Not for me no

[subtle plover]

that means the cbuffer oveheard is gone

[acoustic sapphire]

Not for me either. Only 1

[acoustic sapphire]

Good sign!!
