✅Luma: Prey (2017)

[acoustic sapphire]

What happens in 1?

[wintry kestrel]

Since you are on Linux aswell do you find your peak brightness slider saves between exits? Mine always resets to about 2000nits. Don't have the problem on Windows

[subtle plover]

1 unhooks the cbuffer mapping funcs

[valid kiln]

not much success for me

#1262582420239286372 message this one is better

guess its time buying new cpu when i have spare money

[acoustic sapphire]

Yeah, mine always resets to 1499.

[wintry kestrel]

Did you try setting the mode to 1?

[valid kiln]

yes it give full performance

5&6 deosn't seem to affect anymore, perf stay low

and 5 to 7 stay the same perf

[subtle plover]

Close to no reshade at all?

[valid kiln]

yeah

[acoustic sapphire]

There's probably a way to set a Proton environment variable or some such to change the peak brightness reported by "windows". If I figure it out I'll let you know

I was hoping the peak I set in my KDE plasma HDR config would translate, but looks like it didn't

[valid kiln]

if you use gamescope, the option exist to limit maxnit, i used it when i tried linux with hdr, but i don't remember what exactly is that command

[acoustic sapphire]

yeah, that only works for the default inverse tonemapping built into gamescope unfortunately

[subtle plover]

Did u all try to disable dlss/fsr too?

[valid kiln]

yes i don't use optiscaler

TAA from the game (but using xess or fsr don't help)

[acoustic sapphire]

Yeah, if I remove optiscaler and use ingame TAA only, it doesnt change anything. If i then turn off AA completely, no change either

[wintry kestrel]

I've been using SMAA and TAA from the game with mode 1 and working perfectly.

[acoustic sapphire]

yeah, for now just playing with mode 1. it breaks AA but otherwise the game is running great

[acoustic sapphire]

This games visuals have aged really well, especially with Luma

Lighting is also great, I'm guessing there is baked GI going on

[spice elk]

Hello, which of all the previous files is the most recommended version or what is the last version that must be tested? (RTX 3070)

[acoustic sapphire]

What CPU do you have?

Best bet for now is just use the pinned alpha build. There are some CPU performance issues Pumbo is working on but that build is still perfectly playable.

[spice elk]

Ryzen 5 3600

[acoustic sapphire]

Give the alpha a try, if you have performance issues, you might just need to wait a bit, I'm sure the issue will be fixed soon as the source of it has been isolated

[spice elk]

@acoustic sapphire this version?

[spice elk]

Ty!

[acoustic sapphire]

Yep!

[slow drift]

Hi there, trying to get Luma to run - but I am getting weird flickering and dark areas on parts of the screen. Which is the latest version I should use? Thanks!

[slow drift]

Nevermind, I think I made the mistake of installing ReShade before copying the files over. I re-installed ReShade and now it seems to work?

[blissful bison]

I think the ultra lights mod causes some flicker sometimes, idk at some point I kinda gave up and played unmoded

prey modding is a bit of a mess atm

[zenith isle]

so witch of these three would be most suitable for an older cpu (7700k) that doesn't have that much cache, though cache speed is very overclocked... and i have very fast ram (3600mts) that is not typical for that time period of 7700K

and which would be best for a high cache cpu? I do also have a 5800X3D at my other home in the city, but i wanted to try it out here at my small house in the country too with an older machine..

[subtle plover]

I don't need any further testing atm. Once I've polished it, there will be a new release.

[zenith isle]

oh ok

[subtle plover]

do not play on the test versions above

there was a bad memcopy that overrides random memory

could have all kind of consequences

[acoustic sapphire]

Ok cool, I'll avoid it. Should I just stick with the pinned alpha

[hushed frost]

I think I am having the same problem as the user above, but I cant fix it. The game looks extremely dark and aliased with the mod enabled. I deleted the entire game and saved game folder, reinstalled the game, extracted the mod, installed reshade using the preset, and when I open the game its extremely dark and like AA is disabled, but my screen says its using DLSS preset K

also theres 10k of this spammed in the reshade log 00:43:54:388 [18736] | WARN | [Prey Luma] LoadCustomShaders(Unknown hash: 0x218ab78e)

in case anyone is wondering, its because i enabled "smooth motion" which apparently doesnt work well with reshade, because it worked well without it.

[subtle plover]

Ask NV/amd to fix their implementation 😜

[lone nacelle]

shortfuse fixed it in reshade but it's not in the official release yet, but there's a dll on the server here somewhere that fixes the incompatibility

[lone nacelle]

not nvidias fault

[subtle plover]

what do you mean?
It knows the swapchain is scRGB

[lone nacelle]

idk ask @fossil igloo what he fixed

[subtle plover]

we hook the swapchain creation flags, whether they have an extra proxy or not, it should see it as scRGB.

[hushed frost]

Do you happen to remember where on the server it would be? I've been looking and I can't find it.

[subtle plover]

@lone nacelle fix fov plsssssssssssssssssssssssssss

[acoustic sapphire]

@subtle plover Did you end up figuring out what the performance issue was? Was it the cbuffers? 🤔 I've gone back to playing the pinned alpha for now like you said, interestingly enough the Reactor level has the same big drop when looking down into the main room, I'm guessing due to all the objects on screen

you werent kidding about the gpu limiting thing. If I force gamescope to use 5120x2160 and then enable FSR, then finally output at 3440x1440, the fps on the alpha build is WAY more stable

[acoustic sapphire]

My man is COOKING

[slim saddle]

He always cooks, several dishes at once… 😉

[subtle plover]

https://www.reddit.com/r/prey/comments/1my64jf/wip_mod_update/ ultra lights modder is back

for a mod tailored for Luma

[valid kiln]

Nice!

will still be two separated mod right ?

[subtle plover]

dunno, the guy wrote me a couple times

but on nexus forums 🤣

said he doesn't use discord

so RIP

[acoustic sapphire]

Very nice

[subtle plover]

ReShade updated to take my VRR support proposal

no more frame rate lock issues

@bitter gust Prey Real Lights developer is here 👋

[bitter gust]

Hi! i'm been invited by Pumbo to join in! I'll drop a test file for the mod to use alongside LUMA for those interested!

https://limewire.com/d/I1hoJ#iCOVUJVzqx Note that some level specific changes may be only visibles on new saves (it's simply how the engine handles level-state history) Feel free to send DM for feedback!

[subtle plover]

@acoustic sapphire @valid kiln dunno if you use that mod, but if you wanna help testing

[acoustic sapphire]

Awesome! I do use it, will absolutely give it a test when I play next 😁

[bitter gust]

https://limewire.com/d/I1hoJ#iCOVUJVzqx

Sorry, now it works

[little saffron]

thanks! ill check it tomorrow

in any case I wanted to replay the game

[summer elk]

wait what was wrong?

[subtle plover]

luma set "allow tearing" on the swapchain

which allows VRR

proper vrr

but the preset call didn't allow vrr

and reshade gave no access to that

some gpus didn't know how to behave and locked to 60Hz

not NV though

[summer elk]

I see

[valid kiln]

i will try test the mod tomorrow

did you made some improvement on our cpu overhead situation that i can dl?

[subtle plover]

no

doing 75 mods at once

now it's mafia time 😛

[valid kiln]

[subtle plover]

learn to code and fix it!

[valid kiln]

i'am the man with the ideas

[acoustic sapphire]

I might actually try my hand at it and make a PR if I make some good progress. Just need to set up my dev environment 😁

I take it that's allowed right?

Would be very cool to be able to contribute to the project

[subtle plover]

you are very much welcome

[acoustic sapphire]

Awesome!

[subtle plover]

just, like... it's not the easiest thing

cbuffers reverse engineer

but Izueh got far.

[acoustic sapphire]

Yeah, I know, it's definitely going to be a rabbit hole 🤣 but it will be a fun one

[valid kiln]

ok i will try the mod today

[subtle plover]

@acoustic sapphire @valid kiln

i can send u a CLANG build

and a MSVC build

and u can compare performance

it might be improved.

[valid kiln]

ok do it

[valid kiln]

my prey folders are ready

[subtle plover]

BioShock 2 in the making 🙂

no Prey without BioShock

[acoustic sapphire]

Sounds good, happy to give it a bash

Was busy trying to set up my dev environment recently, only just started playing around with compilers (I did manage to get msvc running through wine)

Is there actually a performance difference between msvc compiled binaries and clang ones? 😄

[subtle plover]

that's what i wanna figure out

[acoustic sapphire]

Cool! Time for some science

[spice elk]

Luma(v98) and test RL, in apartament and with new game

[subtle plover]

you cannot use the Prey luma from the auto builds

unless you put it on top of the nexus version

[tranquil glade]

how did you make optiscaler ini load reshade64.dll

[spice elk]

I Use this as a base. Should I use the mod then the nexusmod?

[subtle plover]

no no, nevermind

[bitter gust]

It seems not RL related, tested but can't replicate.

[spice elk]

Hi, do you have any mods installed? I use chairloader latest version of github actions. And I have 5 mods, touchmod,Shuttle Bay Fix , this other one:https://www.nexusmods.com/prey2017/mods/164, and other 2 that are only playable modifications. I'm not in front of the computer right now, can it be the previous graphic mod that modifies the game.cfg?

[spice elk]

Si eso luego envió la lista de mods, y quito modificaciones del game.cfg

r_ShadowJittering = 1
r_ShadowBlur = 0
r_ShadowCastingLightsMaxCount = 16
r_ShadowCastingLightsMaxCountPerObject = 4
r_ShadowPoolSize = 4096
r_ShadowPoolSizeFirstFrame = 4096
r_ShadowPoolSizeScale = 1
r_ShadowPoolSizeScaleFirstFrame = 1
r_ShadowQuality = 3
e_Shadows = 1
e_ShadowsOnAlphaBlend = 1
e_ShadowsMaxTexRes = 2048
e_ShadowsResScale = 2

r_EnvTexLightProbeMult = 2.0
r_Sharpening = 0.4

Sorry, in English. Then I send complete mod list and remove previous modifications from game.cfg.

[spice elk]

👆 👆 y thank you!

[bitter gust]

Hey, you don't need mod164 (you get better results using RL+LUMA) This test version is made to use alongside LUMA. Any other mod that changes modded files inside the delivered pak will cause conflicts, keep it in mind.

Install LUMA first, then use the Level and pak files from RL, you should be fine that way.

I use also personal preference mods but only the one that changes HUD stuff to clean the screen.

Mantengamos en Ingles así cualquiera puede leer y es el idioma que se usa acá.

[spice elk]

Hi, sorry again, what version of luma are you using? I have installed the latest, from github in a clean install of prey gog, without any mods, and deleting the configuration folder. And when I start the game and open the shutter of the apartment there is a big black spot. So I intuit that it is not your mod.

[spice elk]

Same problem with luma version 100. Clean install, only luma installed and I get a huge black dot on the screen. Does it work fine for the rest of you? I'm on the gog version of the game, if I install prey luma v3 alpha again, everything works correctly.

[acoustic sapphire]

I get the same issue

[subtle plover]

what's the problem? I'm not following.

[slim saddle]

There might be stuff missing from the latest builds as it’s mentioned on github for Prey speciffically?

[subtle plover]

i'm doing a bit too much atm

40 mods at once

hard to keep everything updated

yes.

[slim saddle]

Ya, was trying to help with an answer for the question above. You are awesome anyway!

[bitter gust]

Actually 1.7

[bitter gust]

It seems, I overlook the last version

[bitter gust]

Don't worry the one i'm using it's great. You mentioned something about an extra perf hit in heavy areas, that is in the last ver or in this one too?

V3 Alpha 1.7

[spice elk]

Later I will send either a screenshot more or a video with my cell phone so you can see what I mean.

Black spots, huge black dots.... I don't know how to describe them technically better. Sorry.

[subtle plover]

Windows 11? Linux? Gpu? Tell me everything!

[signal violet]

Is it just me or does controller in this game feel awful
(completely unrelated to luma)

[languid jacinth]

You need to disable steam input in the options
Or google how to enable mouse smoothing in cryengine

[signal violet]

ahhh

[acoustic sapphire]

Yeah this is exactly what I referred to when i mentioned experiencing the same issue

Linux
AMD 7900XT

I've actually been experiencing it every time I tried one of the automated builds since you first had me testing those tweaks to narrow down the performance problems. I just assumed it was cause you were busy with Prey still 😄 sorry

(Those test builds /the old alpha work fine)

[subtle plover]

What item does render black?

[spice elk]

Sorry. Windows 11. 24h 26100.5074. NVIDIA Rtx 3070. Last Driver: 581.15. Versión Prey: gog 12742273. Versión luma with issues: 98,100,

Reshade: 6.5.1.2008

[subtle plover]

and this is with builds from github?

they are not meant to be used

Prey the biggest mod

only what I share here should be used

I haven't tested the changes

yet

[spice elk]

Yes with versión 1.7 is ok.

[subtle plover]

ok, i'll fix it when i get back to it

[spice elk]

Ok. Ok. If you need any additional data or log, let me know. I was going to try now with the 102 version that I have seen that you have published.

[spice elk]

And excuse me for the delay.... Thank you for answering!!!

[subtle plover]

no need for now, it's not tested.
I'm gearing up a new release.

but it's not the biggest priority yet.

[spice elk]

👍 and thank you!!!

[subtle plover]

New builds should work on proton out of the box.

[acoustic sapphire]

So freaking peak.

[arctic lynx]

I encountered a problem with a black screen when going into open space if certain reflections are disabled in the autoexec.cfg and system.cfg files (r_SSReflections = 0).
The problem occurs when going into open space if DLSS is enabled; it does not occur elsewhere.
Is it possible to disable r_SSReflections? I use FSR 3 via Optiscaler, and with it, many reflections constantly flicker.
I am also attaching a video.

[subtle plover]

Is this on the nexus build? We've already fix it otherwise

[arctic lynx]

I am using Prey Luma v3 alpha 1, which is in the last pinned post.

[subtle plover]

It's been fixed. But we don't have a fully stable build yet after that.

[subtle plover]

✅Luma: Prey (2017)

[sand olive]

@subtle plover whats the deal with https://www.nexusmods.com/prey2017/mods/149?tab=description
is it dead now luma is out? I assume luma is preferred?

[subtle plover]

this is luma.

[sand olive]

ok so it's just an old luma build, got it

[south bramble]

@subtle plover hope you dont mind the ping, if i want to play prey with luma what do i install? the nexus build? the last pinned thing from march? or has there been anything since then?

[subtle plover]

last pinned

[south bramble]

thank you

ultrawide is supported properly?

ah yeah says on nexus page, wasnt sure because first post said subject to change heh

[cloud moss]

Chief plays on a 32:9 monstrosity

Ultrawides are supported yes

[south bramble]

24:10

[cloud moss]

Not talking about you

[south bramble]

oh

[south bramble]

is it normal that Luma reset the nits value back to 1499 nits for some reason?

i was playing yesterday and had it set to 2500

today i boot game its back at 1499

[wintry kestrel]

Think it is fixed in the latest versions

[south bramble]

I use the latest

[subtle plover]

You use the semi stable latest.

Highly is fixed but unstable

[south bramble]

This is what I use

I mean it’s not that big of a big deal just inconvenient

is flickering like this also fixed in the unstable build btw?

[subtle plover]

That's a game engine bug. Can't fix

[south bramble]

ah fair

i didnt play prey before so hard to tell if something is vanilla issue or caused by luma

[south bramble]

Damn, Prey is great so far, and looks so good with Luma, HDR and DLAA

[bitter gust]

Hey! The V2.0 of my Prey mod it's live, ready to go alongside LUMA! Thaks Pumbo for the feedback and for your great work

https://www.nexusmods.com/prey2017/mods/22

[subtle plover]

very nice!

so you are not bundling reshade effects anymore?

[bitter gust]

Only a couple for SDR users of LUMA to help with the output, but nothing special

[subtle plover]

what does this do?

[bitter gust]

Tryed today for first time on my TV with HDR, blows me away

Great work

[subtle plover]

being endangered by enemies doesn't apply the weird decoloration effect anymore 😛 ?

No more overdarkening on "fear" postfx due not look good in HDR, instead new vectorial blur on the edges in close combat

yea

[bitter gust]

Uses the vanilla style flashlight, but needs an update for this one!

I really don't like the vanilla flashlight 🙃

[subtle plover]

i'm gonna make version 2.0 of Luma "soon"

[bitter gust]

Ohh yeah, will wait for it

[subtle plover]

I think it'd be nice to have some before and after screenshots of your 2.0 mod

there's a lot of details in the change list and some videos, but no new comparisons

[bitter gust]

It's hard time wise, due how the engine saves level changes. Needs a proper start to see ALL the changes, without some lights have the sttings altered in the save itself

For particles it's easy

[subtle plover]

btw did you see that Luma

[subtle plover]

comes with autoexec.cfg and system.cfg with a description for every single parameter?

I think your mod changed some stuff that didn't do anything 😄

[bitter gust]

Yep

[subtle plover]

or some other stuff it probably shouldn't have included?

pl_movement.speedScale= 4.3
pl_movement.sprint_SpeedScale= 6.3

do these do anything?

[bitter gust]

They changed console input vars on updates

[subtle plover]

yeah but don't these make the player speed different?

[subtle plover]

ah so i need a new save game 👀 ?

[bitter gust]

On release, many cvars were functional

[bitter gust]

Yes, more close like the initial videos

[bitter gust]

No, you ca use your save file

[subtle plover]

but you can't change the player walking sped without even mentioning that in the mod page 😄 !

[bitter gust]

Don't it mentions on some of the changelogs?

[subtle plover]

never seen that

[subtle plover]

my suggestion:
scrap the change logs, just make a list of features

it doesn't matter anymore how the mod changed from 2018 to 2019 😄

[bitter gust]

Oh been on this many years, my mistake, maybe in the comments!!

[subtle plover]

and it's a graphics mod

[bitter gust]

Youre right

[subtle plover]

so there shouldn't be any changes to gameplay unless they are made optional or highlighted very clearly 🙂

that stuff is based on taste

[bitter gust]

I understand, but also restores some cut stuff that some may take it as more intrussive, like more darker areas. But yes!!

[subtle plover]

just mention it all.

ideally gameplay changes would be in a separately installable file or mod 😛

i wouldn't want them because for the first play through, i'd like a more vanilla like experience on gameplay, with just improved graphics

[bitter gust]

Regarding the saves. I mention the new save for the Before/after cause once you progress the game stores the changes on the levels, but it's not a req for the mod to funtion

Sorry for the slow writting, ans miss spels. i'm not good at all

[subtle plover]

np!

now that it's ~finished, maybe you might get some luck to take comparison screenshots and listing all features in one place 🦾

not fun to do...

[bitter gust]

Yore right, i'll set it more clearly on the desc page

[subtle plover]

do you have testers to help?

[bitter gust]

I'ts never finished finished 😆

[subtle plover]

I know that 😄

[subtle plover]

https://github.com/Filoppi/Luma-Framework/issues/1 Luma TODO

[bitter gust]

Nope, but i thing i'll do the first areas on vanilla to take some SC and vids, and re do i't modded keeping it the more close it as i can

[subtle plover]

ask around here, or in the Prey modding server!

I'm sure you'll find people to help test for bugs, and take comparison screenshots.

[bitter gust]

Thanks for your help!

[valid kiln]

Improve performance

[green oxide]

Hmm, so I wanted to do a new playthrough of Prey now that Real Lights is compatible with Luma. I'm running an RX6800 at 1200p and loading up an old lategame save file in the main Talos lobby, so I'm not sure if that could have something to do with it or not, but looking across the center of the lobby area immediately drops my FPS to about 40.

Considering I originally played the game on an RX480, I thought this should be able to handle the extra bells and whistles with little problem.

This is also my original install from 2017 though, and I had previously installed the previous version of Real Lights, so I'm not sure if what I'm seeing is expected or if I should do a completely fresh install or not. Or maybe I'm just wrong about the RX6800 performance.

But I thought I'd pop in just to see if anyone had any insight.

I'm not using HDR and not doing any upscaling.

Oh, and I did notice that SMAAxT2 (or however it was spelled before) disappeared, which I think might be intentional from Luma. But man I forgot how bad the edge shimmer is in the game.

[subtle plover]

known issue, in busy areas FPS drops a lot, there's beta builds with fixes but nothing stable yet.

Soon to come.

[green oxide]

I thought it could be something like that, just because the lobby is a pretty big area with a lot of object density.

So it's a Luma specific thing then?

I wasn't sure where the bottleneck was, since while getting the drop from 60fps to 40, my CPU was only at about 40% and my video card was varying between 25% and 50%.

I'm not sure if there's a better AA solution for AMD cards, but it seems like Nvidia's DLAA does a pretty fantastic job of taking care of that edge shimmer.

[subtle plover]

i'm adding FSR 3

right now

[green oxide]

Ah yeah, the video I had seen earlier was using Optiscaler as a plugin which let them use FSR3 or DLAA.

Ah yes, this was the video https://www.youtube.com/watch?v=9kgRTEnUsNU

I rewatched part of that video, I forgot he had switched back over to TAA. So I booted the game back up and switched from SMAA to TAA and that did help with the absurdly blatant edge shimmer anyway. I'll have to remember that...

[wet harbor]

for reshade do i need to select any of the additional options or just keep clicking next

[subtle plover]

No presets

[south bramble]

aww man i didnt know thats a thing, seems nice but im almost done with the game i think

[fervent lodge]

Hello. Thank you (everybody) for making the game better and looking great. One question. How to install Luma mod alongside the mod Real Lights plus Ultra Graphics Mod? They share some same files... Thank you

[subtle plover]

read luma instuctions.

[fervent lodge]

I have. I haven´t used the "autoexec.cfg" and "system.cfg" files from Real lights mod as stated in the readme. 1. There is an "engine.pak" file in both of these mods. Should I just install the Luma one?

2. Another one is the "game.cfg" in GameSDK folder. Both of these mods have it. Should I use the one from the Luma mod again?

[subtle plover]

@bitter gust maybe you can answer that

[subtle plover]

probably yes, that's how it was for the old version, unless the new version changed anything

[bitter gust]

You can replace all the files, without a problem. There are some things that are a little different, but in essential are pretty the same, and don't have any trouble. Engine.pak change some variables for escalability

Not in PC ATM to give a more detailed answer sorry, would report back the extaxcts differences later 🙃

But for a short answer, yes replace all and remember to ser you VRAM !

Forgot to add that I respect the cvars that Pumbo change to give compatibility, the ones in RL expand the view distance a little and the added ones are for the intended "feel" of the mod.

[fervent lodge]

What do you mean with setting my VRAM? How and where to do it? Have Nvidia 4090

[bitter gust]

There some added ones that do not function any more so don't make difference at all

[bitter gust]

Look at the txt included in the downloaded files 😊

It should be the equivalent VRAM in MB, set it on the pool memory cvar on the cfgs files

You should see it easily

[fervent lodge]

Thank you

Last question. Sorry. Should I first install the Luma mod and THEN Real light mod with overwriting the engine.pak and game.cfg files? Or the other way round?

[bitter gust]

First LUMA, then RL

[fervent lodge]

Sorry. Me again. I have set the pool size texture to my VRAM's amount in MB. The question. Why is it so important?

[bitter gust]

Since making the mod I noticed that improves texture streaming and shadows issues. It's not a pure cyengine build and memory grow up thru the years but I keep it to mitigate any problems

Edit: spelling

[light rover]

what do adaptive resolution lower and upper fps tolerances do? I've been playing around with the settings but can't figure out exactly how they work

[sleek gorge]

Are any extra mods recommended to be used with this? Or QoL stuff

[south bramble]

Honestly not needed

I just finished the game

I had something installed that makes more loot drop so I can salvage more stuff for crafting because I couldn’t be arsed to manage ammunition

But that’s it

Had no bugs/issues or anything with Luma

Except DLSS blurring text on the computer terminals a bit

[dense elbow]

Hi, i'm running into performance hit with the mod and it's pretty annoying. I've saw that GTAO was the culprit apparently, so i deactivated it but the perf remains the same. I'm on a 5600X and a 9060 XT and when i'm in the Hall i'm running at 50-55 fps, pretty annoying. Also, i tried using optiscaler but it doesn't really work and i can't change the render res (don't know why). If someone can help, would be greatly appreciated

[valid kiln]

no fix for the moment, pumbo is working on a perf fix

Put the game aside and wait for the Luma update for now

[subtle plover]

I'm just wrapping up Thief and Trine 5 and then I'll get to Prey performance.

[dense elbow]

That's good to hear, i'll wait then ! Good luck on those 🙂

[green oxide]

Depends on which Thief

[subtle plover]

the latest build should have the transformer model exposed in the settings

I think it looks worse

but, feel free to use it.

[bitter gust]

Honest question: Preset K don't suppose to have less gosting on small moving pixels? Tbh I set it on nvcp when installing LUMA and didn't compare it properly

[subtle plover]

it has massive ghosting on fog and reflections

it breaks immersion

[bitter gust]

Great to know!!!

[subtle plover]

could somebody boot the latest version from github and let me know if it works good overall?

no time to test, i refactored DLSS.

[fervent lodge]

can find it..is there any lik for the github release?

[languid jacinth]

DLSS looks fine, but I'm getting artifacts on the transparent textures that turn them solid black

Ctrl+F "Prey"

[subtle plover]

how do i reproduce? all transparent textures?

[languid jacinth]

I can send you the save

[subtle plover]

they look fine for me. could anybody else try?

[fervent lodge]

I have the same issue. Black something with transparent textures.

@subtle plover

[subtle plover]

GPU?

[fervent lodge]

NVIDIA 4090

[subtle plover]

can you send a screenshot?

or video

[fervent lodge]

Typhon runnig towards me

[south bramble]

[fervent lodge]

@subtle plover Don´t know f it does make a difference.. I´m using the Optiscaler (DLSS 4 AI Setup) from this guide: https://www.youtube.com/watch?v=9kgRTEnUsNU

[subtle plover]

mod literally support DLSS Transformer model natively now, optiscaler will just hurt performance

also rcas is already enabled in the mod, you are doing it twice.

[fervent lodge]

I have got lots of fps . I already have turned rcas off

[subtle plover]

there's no no reason to use it

more likely to do damage than not

[fervent lodge]

after I set the DLAA preset to G the jagged edges disappear completely

[subtle plover]

that would probably result in more ghosting though

[fervent lodge]

I haven´t seen any ghosting (with the latest Luma version = not the Beta one)

[tender helm]

still the same black artifacts. thanks

[subtle plover]

Gpu?

[tender helm]

5070ti, latest drivers

[subtle plover]

FSR 3 has been added to Prey Luma if anybody wants to give it a test

[fervent lodge]

Great answer

[hallow oxide]

Hi, I have lame question. If I want to download latest Prey Luma I have to use latest release from Luma-Framework github combined with modified game paks and configs that I have from older version of Luma downloaded from Nexus? Or where to download latest configs/paks or are they still even necessary?

[fervent lodge]

Delete the old Luma files, verify or install the game a new and then download and past the Luma files from nexus...

[hallow oxide]

But luma on nexus is old version isnt it? On github there is much newer build (but without paks/configs). So my question is about this

[slim saddle]

Use the one from Nexus, also if you use, update the Real lights mod also from Nexus as the latest update was made to work with Luma

[fervent lodge]

The new one is the latest beta. But there are some issues with it

[subtle plover]

the mod is in between versions as of now.

a bit messy.

soon 2.0 will be done.

[topaz iris]

Finished my first replay of this game just now with luma and the real lights mod on a modern oled and it looked fantastic, moreso than I would have imagined. Floating in space with all those small, bright lights in the darkness. Too bad I seem to have missed 2.0 but oh well.

Just wanted to say thanks to all involved, doing good stuff like this for everyone to enjoy 🙂

[subtle plover]

the bug where the weapon fov would change to default after loading into a new level should be fixed now

if somebody wants to test the latest build

(don't try FSR3, it might crash)

enable lens distortion (perfect perspective), increase the scene/main FOV (the weapon FoV should auto scale with it)

then play a bit and then load into a new level

it should now persist

[faint blade]

Hey! There seems to be a company making a plugin for Unreal and Unity that does basically what Pumbo did for FOV in Prey. Have a look-see: https://www.youtube.com/watch?v=wYAUyJXwvG0

If the solution is perhaps superior, I wonder if someone could reverse-engineer it into a reshade plugin 😄

[subtle plover]

I had a call with them last week.

their solution doesn't really apply to mods, it's more of a native implementation and requires some work.

[faint blade]

Oh well... But it does look good indeed! Would it then perhaps be feasable to mod the plugin into existing UE games perhaps?

[subtle plover]

not really

[slim saddle]

I’ll take what Pumbo did for Prey for pretty much any game!

[sand olive]

unity and unreal already have panini projection i think

[ocean cedar]

It seems that Perspective Correction reduces sharpness more than I thought 🫣

[pliant nexus]

Old thread... but how do I get the vertical FOV to save? I'm playing at 32:9 so I increase the vertical FOV but it keeps resetting to default every time I reload the game

[subtle plover]

it's fixed on the nightly releases but

they aren't stable

i'll get back to the mod

[pliant nexus]

I was able to fix it by deleting the game, re-installing the game, and of course re-installing the mod

well, it seems fixed so far

[vital bear]

New user here. I got the same black texture issue. I didn't turn on any upscaling methods, because the DLSS would make my game super laggy for some reason.
Mod setup is: Pinned v3 alpha 1 + github latest update, HDR on.
GPU: RTX 4090
I have other mods installed, if it is caused by other mods, Touch-up would likely be the only one that involves graphics. My other mods are like inventory size and remove hacking, etc. No big mods like overhaul on difficulty.

[vital bear]

I just tried v3 alpha 1 only without any new updates from github, and it solves all the issues. No more black textures!

[merry cairn]

Hi, I´ve got a question, It says on the settings for Luma on Reshade that it's best to leave game brightness at 0 but what if I can't see the left logo at all until 2? Should I leave it at 0 or 2? Using Windows 11, HDR calibrated with HGiG on

[molten wharf]

Default brightness

[sand olive]

dlss update?

[subtle plover]

it's in

[sand olive]

nice, dno if you want to update nexusmods or not

its been a while and not seeing any install instructions

[sand olive]

4.5 you mean?

[subtle plover]

I need to fix the performance before

and move DLSS before TM, and fix some color grading stuff

[sand olive]

oh god yeah the perf is awful

like 5fps oof

enabling / disabling dlss is rough too

[polar elbow]

The release on Nexus doesn't play well with the prey lights mod despite prey lights claiming it does

[vital bear]

Will the black transparent texture be fixed as well? 👀

[sand olive]

isnt that a bug in vanilla

[little dock]

the whole screen jitters with dlss enabled and also sky is black

[rapid reef]

thanks for making PREY more amazing for me in 2025. I wish to now try mooncrash but im having issues with the mod. PREY luma mod runs perfectly at 60fps and looks amazing in 4k. BUT mooncrash runs at 30fps and on 4k looks bad and wont let me change resolution and stay in fullscreen despite enabling fullscreen etc. Any ideas if LUMA works with mooncrash and how to get that fullscreen 60 fps sweet spot ? thanks

[subtle plover]

try steam+epic+gog

they are all different

one might have issues

also, try without luma.

[rapid reef]

thanks, does luma not support mc dlc? also how do i turn luma off for mooncrash? i installed it last year ...

[little dock]

dlss jitters the screen any ideas why?

[fast cairn]

nice mod

[muted summit]

Does this happen to anyonr else?

Haven't been able to fix it for ages

[subtle plover]

nexus version?

[muted summit]

Both nexus and github test version

happens on both modded and clean installs

[subtle plover]

seems like a vync or gsync problem

vrr

too many frames

monitor goes boom

[muted summit]

What should I set to?

I have Gsync enabled in the Nvidia control panel

[muted summit]

anyone else have this issue

[subtle plover]

it's a HW issue, it's not related to the game.

[muted summit]

hm ok i set it to fixed refresh manually and now its working

ill see if it comes back because sometimes it's inconsdistent

it doesnt happen without luma installed though

nvm i fixed it vwith gsync on

changed this setting to application controlled

it was originally set to highest availible

[pliant fable]

If you want to make sure gsync works properly you need vsync enabled in drivers and a framelimiter at 160 fps or so

[south bramble]

i played through prey without any such glitches a few months ago

[sweet thunder]

Is there anything i can do about jitter with dlss enabled?

[subtle plover]

shoul;dn't be any

[sweet thunder]

I was using the github version, but i just switched to the v3 alpha and its good now

[vital bear]

I was using the github one too, but it lags so much and has black texture on transparent stuff like smoke. But switching to v3 alpha fixed it. Although my game still crashes from time to time, no idea if it's luma or my other mods.

[jaunty star]

bruhhh i've literally had the same issue forever

still haven't been able to play the game

[jaunty star]

i managed to fix this issue thru the nvidia app instead and I just adjusted Prey's "driver" settings (monitor technology) to fixed refresh instead of g-sync. thx for sharing a fix

[muted summit]

There's a better fix that allows you to use Gsync

change this setting to application controlled for Prey's Nvidia Control Panel settings

[jaunty star]

bet thank you ❤️

[chilly tree]

Hi is it possible to install this on deluxe edition of prey from Epic Games?

ok found my answer but how to actually remove old version ?

[modest comet]

This has to go into the folder with the exe right?

This is the github version not nexus

Nexus filestructure was completely different

[valid kiln]

wonder if the cbuffer are reworked now. been waiting for my ng1

[tepid juniper]

Anyone else getting lag spikes and VRAM leaks when closing the inventory sometimes? I'm using Optiscaler which might not be helping but it looks like 'DLAA' is being loaded at least sometimes when I open the inventory and then it switches to an upscaling model when I close it. Looking at the Optiscaler logs, it doesn't look like the old DLSS feature is being destroyed so I'm running out of VRAM after 5 or so of these instances

[subtle plover]

please try without optiscaler

[subtle plover]

also, nexus build?

[tepid juniper]

I don't think the issue happens without it but I'm on AMD so it just uses TAA rather than DLSS. I might be able to borrow a NVIDIA PC but I was hoping someone might be able to confirm

[tepid juniper]

Originally the Nexus build, then I recently tried the alpha that was posted here. I also used Optiscaler 0.7.9 before upgrading to 0.9.0 when that released

[tepid juniper]

According to Optiscaler's logs, NVSDK_NGX_D3D11_CreateFeature is being called for 3840x2160 (my monitor's resolution) and then for 2560x1440 (the internal resolution I'm upscaling from), back and forth. NVSDK_NGX_D3D11_ReleaseFeature doesn't seem to be called at all, although I guess it could be caused by a quirk in how Optiscaler behaves compared to the DLSS API.

Optiscaler doing this might also not help but DX11on12 would probably cause bigger compatibility issues and I don't think it's much of an issue
hkD3D11CreateDevice Overriding D3D_FEATURE_LEVEL, Game requested D3D_FEATURE_LEVEL_11_0, we need D3D_FEATURE_LEVEL_11_1!

This was for FSR 3.XX on a RX 9070 XT but the issue seems to be worse with FSR4, presumably because that's a bigger model and it adds DX11on12 into the mix

I guess I could try using 'DLAA' and see if that works. Although the performance won't be great

But I could see if it tries to switch from 3840x2160 internal resolution in-game to 3840x2160 in the inventory

Also by by the inventory being open I technically mean the DRS is inactive, from having a quick look at the Prey Luma source code

[glacial hedge]

is possible to make the mod work with optscaler withoutr having the reshade installed? for some reason my performance tanks when I get reshade instaled low fps and low cpu and gpu usage

[tepid juniper]

It's not doing something silly like defaulting to an iGPU is it?

[glacial hedge]

how can I check for that? my cpu is a Ryzen 5 3400g but I use a RX9060 XT with it

[subtle plover]

The issue is fixed on the github builds.

[tepid juniper]

I think task manager might show 2 different GPU utilisations per process? I've only ever had devices with either a iGPU or a dGPU, not both, so I'm not quite sure. You could also open AMD's overlay and see how the numbers compare between in-game and idle. Even if the utilisation is low, I would have thought the VRAM usage and/or power consumption would increase significantly. You can change it here but there's a chance the mods are confusing Windows, I noticed I add to manually add Prey to get that screenshot (although I don't have an iGPU so I didn't need to change anything here).

While you're at it, you might as well check if the monitor is plugged into the GPU rather than the motherboard and check your refresh rate is set correctly in Windows settings

[tepid juniper]

Oh cool, thanks. I tried to compile it from source to test some things but didn't have much luck. I almost tried the build from there once I realised it was still included in the releases but didn't really understand the instructions

Is that the recommended build now over the Nexus version? Or just if you're running into issues and need the newer version?

[glacial hedge]

the integrated graphics are disabled while a GPU is instaled, even if I wanted I couldn't plug any monitor on the motherboard while a GPU is instaled

[tepid juniper]

Ah good, I thought that troubleshooting might have been too basic. I guess see if there's anything unusual about the stats. Is it working properly in other games? Are you using DX12 via Optiscaler? Maybe there's an issue with DX12 in general but not DX11?

[subtle plover]

Not really. It still has problems

I guess, don't use optiscaler, or help us fix the issues 😅

[tepid juniper]

I might try. C++ is scary though 😂

[glacial hedge]

I did the whole process at first, the luma, the reshade and the optscaler, now I'm trying one step at time, I instal the luma files, the game runs well, then the reshade and the game runs like 40 to 30 fps

[tepid juniper]

Is the dxgi.dll in the build just unmodified ReShade? I normally load ReShade via Optiscaler

[subtle plover]

I think there's just some black dots

[tepid juniper]

Hmm. I think the mod only replaces a few assets without Reshade, it won't run in HDR and you won't be able to use Optiscaler or anything. What's the framerate before you do that though? I think the game defaults to DLAA so the rendering is just as expensive and then you add the cost of upscaling on top of that. You get the best image quality but I'm guessing that's not what you want?

According to the README, the performance cost of the mod itself should be negligible

[tepid juniper]

I guess we'll see 🤞

[tepid juniper]

You have to use the game's dynamic resolution in order to use upscaling. I think the game's timer or at least the animation timer gets kind of broken though with the default settings. I had to set my target framerate to 240 so that it always runs at the minimum res trying to reach it. Otherwise it seems to constantly change the resolution even when standing still. I wonder if that had VRAM leaks 🤔

[glacial hedge]

36 fps, gpu at 24% and cpu at 40%

if I delete the dxgi.dll from reshade it goes back to between 120 and 150

[tepid juniper]

Oh yeah, I forgot about the low utilisation part 🤔

What's the VRAM utilisation and power consumption like?

[tepid juniper]

I don't see them so far, but for some reason I can't open ReShade or Optiscaler's menus, even though the mod seems to be running

Ignore me, I forgot to install Optiscaler 😂

[subtle plover]

There's a performance problem in busy scenes.

Fix is WIP

[glacial hedge]

that was like in the very beginning but it's fine, I'll wait 🙂

thank you guys!!!

[tepid juniper]

What's this referring to exactly? I took the Nexus build, replaced the files in the release folder with the ones from the latest build, deleted the dxgi.dll and replaced it with a fresh install of ReShade + Optiscaler. Should I use the asset files from the alpha build? Or does the mod only need to make changes in the releases folder now?

[tepid juniper]

No problem 🙂

[subtle plover]

Clean all the files

[tepid juniper]

I deleted all the files in the release folder and then verified via Steam but I can try and do the same for the other folders. I just don't want to delete too much otherwise it'll take a while to download

I'm still wondering about that performance issue even though I haven't encountered it. Does it tend to count towards utilisation if a game utilises a GPU really badly? Like if it has thousands of really small draw calls that only require a few GPU cores? 🤔

[subtle plover]

It's all up in this chat if you search

Complicated

[tepid juniper]

Going to try again in a minute after attempting to delete and re-verify some of the files. Is the dxgi.dll file needed as long as I install ReShade?

[subtle plover]

Use the github Luma version yes

[tepid juniper]

Are none of the other file changes needed? There was a warning about the GitHub version missing some assets

[subtle plover]

Use the shader and dll files from github. Remove the old ones.

The data and configs you should keep the nexus version

[tepid juniper]

Those are all in Binaries\Danielle\x64\Release right? The GitHub version looks like a replacement for that folder so I replaced it in my copy of the Nexus build. I assume the 2 addon files are also needed? I'm guessing this is correct rather than having both the new "Luma" folder and the old "Prey-Luma"?

I presume the new DLL files look in "Luma" folder rather than the old "Prey-Luma"?

I'll try running just that without installing ReShade or Optiscaler and see what happens

Same error. Guess I'll try alpha + GitHub

ReShade did load though, just an old version

std::filesystem::path luma_old_shaders_path = file_path.parent_path().append("Prey-Luma\\");
      std::filesystem::path luma_old_bin_path_1 = file_path.parent_path().append("Prey-Luma-ReShade.addon");
      std::filesystem::path luma_old_bin_path_2 = file_path.parent_path().append("Prey-Luma-ReShade.asi");

      if (std::filesystem::is_regular_file(luma_old_bin_path_1) || std::filesystem::is_regular_file(luma_old_bin_path_2) || std::filesystem::is_directory(luma_old_shaders_path))
      {
         MessageBoxA(game_window, "An old version of \"Prey Luma\" was found, we will now try to delete it.\nBack it up before continuing if needed.", NAME, MB_SETFOREGROUND);
      }

Looks like Prey-Luma-ReShade.addon is considered an old version but is still in the current builds, I'll try deleting

[subtle plover]

delete it.

[tepid juniper]

I've got good news and bad news. The good news is the VRAM doesn't seem to be leaking anymore with either FSR3 via the mod or FSR4 via OptiScaler. The bad news is that FSR4 via OptiScaler results in bigger (and more frequent?) lag spikes than before. And I think alpha textures seem to be a bit broken.

Maybe I'll do some comparisons between FSR 3 and 4 and see if it's worth attempting to add native support for it (although the alpha textures are probably a bigger issue). I don't know what would be involved in that though. I think I might also make a PR to update the README for Prey Luma if that's helpful.

Anyway, I think I'll stick to FSR3 for now and maybe have another look later at the alpha textures. Thank you very much for your help 🙂

Oh and the whole image is vibrating a bit. I guess it's not as fixed as I thought 😅 . Maybe perspective correction is broken

[subtle plover]

FSR4 uses a DX12 swapchain

which AFAIK adds a relevant performance penality

it's probably not worth the jump in quality.

FSR3 is already fine

the game doesn't need TAA that much.

[tepid juniper]

Ah, I forgot about that aspect. I think I might have actually been testing FSR 3 to FSR 4 on OptiScaler though which was working weirdly. When I do DLSS to FSR4, it seems to be mostly working for now. The lag spikes are only occasional

The main thing is the graphical glitches I might see if I can find more about in this thread

[subtle plover]

Black areas in smoke and glass?

[tepid juniper]

I don't think I've seen it with glass but there are issues with alpha textures in general, including smoke. Also the whole image vibrates which is a bit annoying

[azure sparrow]

Hey, I'm confused on what to install and where. The Prey-Luma mod has clear instructions. Is that all I need or luma from github also?

and where do I put luma?

[azure sparrow]

Also, the luma mod isn't compatible with chairloader?

ah found the correct luma in the pins

however, is this not compatible with the real lights + ultra graphics mod since they both provide autoexec.cfg and system.cfg files?

[subtle plover]

read the description of real lights on nexus.

[azure sparrow]

yeah the files just seem structured very differently in both mods, so I wasn't sure

[subtle plover]

pls ready readme and instructions around

every question is answered

[azure sparrow]

I originally installed the nexus version of prey-luma, then I just installed the pinned version here, but chairloader is still complaining. I assume I need to uninstall luma and reinstall

ah what a pain

gonna have to fresh install to get rid of old luma

[subtle plover]

you don't

[subtle plover]

Delete the old Prey-Luma-ReShade.addon and Luma folder before installing.

tha'ts all

[azure sparrow]

Well it launches now, but...

crazy flickering everywhere

[subtle plover]

better reinstall everything then

you probably got something wrong

because it works for others

i can't help there.

read all the instructions everywhere.

[azure sparrow]

I believe this happened to me last time I tried prey + luma and nothing else. I think some setting is wrong, I'll as in luma-support

[torn marsh]

I'm having trouble with the mod. I've installed it following the instructions in the readme and it seems to be working but just quickly testing everything looks way darker than I think that it should

[tepid juniper]

Well... I technically got the alpha effects working in the latest version 😂 . I reverted the "return 1" change, although the assert is still failing

https://github.com/Filoppi/Luma-Framework/commit/7027c630c437f2355511452416dc88a7f150dd85#diff-a230745606b711ad8020f27f92bc3053d289a4a9e2826332a4d8b8c154cbe59dR1771

[tepid juniper]

Weirdly the one on the left stops flashing if I disable the mod but keep the shader overrides active (without restarting). It's still being updated with some faint outlines though. But the one on the right becomes completely black

Oh wait, I think the issue might have just been because of some testing code. So success I guess? I'll have to see if I run into any issues

[subtle plover]

god wtf is that 😄

[subtle plover]

i can push the fix

or do u want to make the PR?

just changing from return 1 to return false

[tepid juniper]

I think I'll test it a bit more tomorrow and make a PR. I want to check a couple of other places where I saw the issue

This instance was so bad that I figured it was a good time to pause my playthrough and try to fix 😂

[tepid juniper]

I think it might be some debugging thing Copilot tried but didn't work. It's very colourful and flashy which is fun. Yet another time I'm glad I'm not prone to seizures 😅

[subtle plover]

i mean, wtf is the mistake i had made.

bad

[subtle plover]

what's your email?

i'll put u as co-author

u can dm me

[tepid juniper]

Thanks. Sent

[tepid juniper]

For the record it didn't do that originally, it just looked like this but in HDR

[subtle plover]

new Prey github builds should be playable again, thanks to @tepid juniper for finding the problem.
Pls give it a try!

[high viper]

Is there a link to the github build? Was thinking of doing a playthrough in the near future and would be happy to test it out if it's relatively stable at this point.

[subtle plover]

https://github.com/Filoppi/Luma-Framework/wiki

[tardy axle]

For EGS version use Prey Luma v3 alpha 1.7z then override w/ github right?

[high viper]

thank you, was struggling to find that mod list page and can bookmark this time. (GitHub is often really unintuitive as someone who doesn't use it for dev work, imo)

[subtle plover]

let us know if it works.

new version is yet untested.

but nothing should have broken

[tepid juniper]

It seemed to work when I tested it for a few hours, that area with the waterfall and smoke was also fixed. The vibrating camera and performance issues still happen though. I also noticed the performance degrading over time although that might be because I was using Optiscaler for FSR4, even if it wasn't leaking VRAM

[tardy axle]

works well w/ Steam + Nexus + 401 + Opti 9.0 + FSR4

crash w/ EGS + v3 Alpha 1.7 + 401 + Opti 9 + FSR4

[tardy axle]

r u on Steam or EGS version?

[tepid juniper]

Steam on Windows 11 with a RX 9070 XT

I used the assets from the Nexus mod though rather than the alpha, not sure if that made a difference

[tardy axle]

yeah EGS only works w/ v3 Alpha 😅

[subtle plover]

github build crashes on boot?

[tardy axle]

No, works well w/ EGS + v3 Alpha 1.7 + 401 but crash when + Opti 9 + FSR4

[subtle plover]

I don't understand 😛

can u spell it out in a sentence

[tardy axle]

😅 sorry for not clear

Using Prey 1.8 EGS version w/ v3 Alpha and build 401 works well

but crashed if I'm using Opti 9 and FSR4

[subtle plover]

ok

@tepid juniper it's not crashing for you?

[tardy axle]

Using Prey 1.8 Steam version w/ v2a (Nexus) and build 401 works well EVEN w/ Opti 9 + FSR4

[tepid juniper]

No, although I might be using a slightly different version since I built it from source a couple days ago

[tardy axle]

@subtle plover v3a has file structure like Steam? Should I just need to move x64 contents to x64-Epic?

[subtle plover]

it should be explained in the readme.

[tardy axle]

ah sorry I missed it 🙇‍♂️

This mod served as a foundation of many of the SDR to HDR upgrade methods we still use in our mods today.
Kingdom Come Deliverance II HDR is also partially based on

hello, is there something wrong with my Luma mod in Prey? DLSS is working great as you can see on bottom left, but the HDR seems to be completely broken? I've never seen the HDR analysis tool give me negative numbers for the minimum level and it does look like my blacks are completely crushed. The max one is accurate as my display maxes out at 800 nits in game mode (LG C3), although the sun seems to be completely overblown in that image.

Also wanted to add, since the readme says the mod uses the windows calibration tool for HDR, I tried to make a new profile to see if it'd fix the issue but it didn't. HDR profile on Windows is normal at min 0 and max 800

[unreal pawn]

and final note, I did swap the dlss .dll to the latest version, don't know if that could have any consequence, it's using preset K as seen on bottom left

[unreal pawn]

and also for some reason the mod keeps resetting to 1499 peak brightness every few seconds despite me choosing 800...

Install the version from github on top

Delete the Luma folder and addon before. Keep the rest.

And don't look at the graph.

If your blacks are crushed, something is possibly wrong with your display as I never heard of that before.

hello i am having an issue with v3 alpha + latest release where teh jitter going bananas

[subtle plover]

@tepid juniper wanna help 😄 🆘

[tardy axle]

EGS?

[granite hound]

What resolution are you playing at? I upscale from 1440p to 4K with FSR4 and it's noticeable but manageable for me. The effect looks stronger in your clip though

I guess the jitter might be in pixels rather than degrees?

[granite hound]

steam

[granite hound]

33

pretty much the lowest setting

im running a 2060 laptop

[tepid juniper]

What's the output/display resolution?

Might also be worth testing if it vibrates less as you increase the resolution percentage. Although the reduced frame rate might also contribute to that

[tardy axle]

I thought EGS because you're using v3a

[granite hound]

what version should i be using instead

[granite hound]

even native vibrates my gpu also cant handle it

[tardy axle]

v2a then github version on top

[granite hound]

ill try that out

[tardy axle]

don't forget delete these from v2a

[granite hound]

nau it still jitters

[granite hound]

ported agx for fun left is hable right is agx

[granite hound]

[granite hound]

Hi, I was using the v3 alpha 1.7 but when I opened and closed the inventory it added an extra 2 GB to the VRAM until it saturated it (16 GB) and started causing problems. I tried installing the GitHub version over it (I read that was the way to do it), and that problem was solved, but now everything is shaking. I tried the stable version from nexus (v2a) with the github one and the issue persist. I'm on Windows 11 with the Steam version.

[subtle plover]

Optisscaler?

[north glade]

Nope.

And I don't use any other graphics mods either.

[exotic rain]

[exotic rain]

if that is the only place you store this release please move to a real distributing platform 🙏

I might provide you with file hosting if you need one

once I assemble it

[exotic rain]

alpha behaving same.

[exotic rain]

so uh maybe you can supply me lowend config instead of me creating it?

[exotic rain]

maybe there is light config around and I just did not seen it?

[exotic rain]

no?

[abstract jolt]

I'm seeing that the mod on Nexus is from 2024. Is this the latest iteration we should be using for Prey HDR and high FPS?

[exotic rain]

no, it makes FPS way worse on default config

[tender osprey]

Can I update the dlss .dll file from the luma mod with a newer one? or will it break the mod?
