[Linux] LSFG-VK

[raven kite]

Yeah

[neon halo]

then maybe maybe not 😏

[raven kite]

what

[sour elm]

Mangohud is showing 64-bit

[raven kite]

Did doom 2016 work for anyone

[neon halo]

I can try on the deck but the game is 70 freaking GB lol

[raven kite]

The latest doom game is over 100gb 💀

[neon halo]

yeah but it makes sense, sort of

assets are extremely high quality, for the most part

[raven kite]

The textures are insanely good

[neon halo]

doom 2016 however is big just because of megatextures

it was a tech at the time that used a giant texture atlas that was decompressed in real time by the CPU

the goal was to avoid consoles VRAM limitations, especially for the Xbox 360 era

but the system proved extremely inefficient with scalability

[raven kite]

But can it run on a toaster

[north quail]

Doom 2016 is well optimized game

so probaby can

[neon halo]

it allowed Rage to run at 60 FPS on the 360

[north quail]

i get 100+ fps high preset, on 1440p, and I have not that good of a gpu, A1000 => 3050

[raven kite]

I get well over 150 fps in Doom 2016 at the highest settings and it's sad that I have to play the latest doom at low and with fsr 3 ultra performance

To get only 50 fps

😭

[neon halo]

but megatextures had to be dropped in favor of the decal system used by their new Vulkan backend for Eternal, much faster / efficient, and saves a ton of CPU performance compared to megatextures decompression

[neon halo]

doom 2016 has some weird moments though, even in Vulkan native, the bridge for example, it never runs well

[raven kite]

They always say the bridge but never under the bridge

[neon halo]

if you load I believe level 3 or 4, and look at that bridge, FPS tanks, but CPU and GPU usage remains low

a mystery

[north quail]

also it crashes if you alt tab, so i run it in borderless mode with window rule set to fullscreen xD

[neon halo]

plenty of situations like that with the pre-eternal engine

[raven kite]

Ok this never happened lol

[north quail]

weird it crashes for me always when i alt

maybe nvidia thing

[raven kite]

May I know your specs

[north quail]

i get this error when i enable LSFG

[north quail]

Dell Precision 5570
Hybird, IGPU + Nvidia (A1000 4gb)

[raven kite]

Same

[north quail]

lsfg is intializing correctly though, maybe something wrong with engine

[neon halo]

what about other Proton versions?

[raven kite]

Btw @neon halo what proton are you using for quake remastered

[neon halo]

regular 9

works on Q2R too

technically I could try the doom + doom 2 source port as well, but frame gen is hardly necessary there lol

[raven kite]

🤔

Doesn't the game have a renderer option?

[neon halo]

it does, software, d3d11, vulkan

[raven kite]

Ok

So

[neon halo]

but I mean, the game runs on everything

[raven kite]

Do I choose vulkan

[neon halo]

for Q2R?

[raven kite]

Quake 1

[neon halo]

always chose Vulkan that's the highest chances of guaranteed success

Quake Remastered only has Vulkan

[raven kite]

Oh

Then idk why it freezes with fg

[neon halo]

it's 2 that has D3D11 as well

yeah it shouldn't mine is flawless

[raven kite]

Imma enable proton logs

This happens

Lemme check the logs now

[neon halo]

Proton 9 ?

[wanton mural]

V3dvk fine?

[raven kite]

Cachyos Proton package

[neon halo]

can you try vanilla 9 or it won't work?

[raven kite]

I'll try later

First I'll check logs but can't do that now

[leaden violet]

you mean vkd3d-proton?

[wanton mural]

Yeah. For pso

2004 old game

Their private server launcher adds d3d12 but apparently its actually vkd3d

[north quail]

i think 32bit game will not work, but apart from that you can try dxvk/vkd3d titles

or opengl , you can use Zink and then lsfg should work

[wanton mural]

Then this is unacceptable then. I have to get pso working

[north quail]

pso?

[wanton mural]

I do not care about other games

Pso blue burst

[raven kite]

Lmao what is vkd3d proton

Too many versions

[north quail]

oh it's a 32bit game

ya you wont be able to run it of now

you'll need to build lib32 binary for it

[wanton mural]

Of dxvk lsfg?

[north quail]

lsfg-vk lib32

@neon halo @raven kite have you guys tested VRR?

[raven kite]

What is vrr

[neon halo]

can't

[raven kite]

😭

[neon halo]

Gsync/Freesync

[north quail]

I think it breaks VRR

let me test some more games

[neon halo]

that would be a bummer

[raven kite]

Uhh my monitor always has freesync enabled

No problems so far

[north quail]

enable the in monitor FPS

and check if it's syncing with the fps shown in mangohud

not the in game fps counter

mine is going up and down

without it works fine

[neon halo]

so if you have a game running at 60 FPS and you frame gen x2 to 120 at 144Hz it is perfectly smooth? (assming you have 144Hz)

[raven kite]

Yeah no i have 75hz

[north quail]

yup with x2 your monitor should use 120fps as gaame is being throwing output

[neon halo]

30 to 60 then, at 75Hz

[north quail]

deafult is 41-75

[lusty talon]

vrr works just fine for me

[north quail]

weird kinda broken for me let me try some other game

[raven kite]

@lusty talon will this ever support opengl

[lusty talon]

chances are it's your monitor lol

[north quail]

but works fine without it

[lusty talon]

via zink

[neon halo]

sometimes it's just Nvidia proprietary drivers being dodgy, happened to me a few times even without any frame gen, reboot in case :p

[lusty talon]

no of course, but you add framegen which inserts frames and flucuates the frame rate by syncing n frames every frame. most monitors can't handle that

[cunning copper]

@lusty talon I'm on the latest commit. Setting any config option other than LSFG_DLL_PATH and LSFG_ENABLED causes games to instantaneously crash. (i.e setting LSFG_HDR or LSFG_MULTIPLIER) Again, only happening with DXVK or VKD3D games and not Vulkan native ones

[lusty talon]

great

i love to see that

send logs, I'll take a look at them later

[final vale]

pan

do you accept money

[raven kite]

Isn't zink a vulkan to opengl conversion program?

[lusty talon]

not if you ask me directly lol

but there is a github sponsor linked on the repo

[lusty talon]

no it's opengl to vulkan, right? lol

[north quail]

it's same as dxvk/vk3d, opengl-vk

[cunning copper]

the only logs are that it says instance created and then immediately dies after that. I think I may have a clue as to what's happening

[north quail]

😦 ah so i can't get vrr with lsfg-vk?

[lusty talon]

lsfg-vk syncs with vblank

you don't get an advantage with vrr lol

[lusty talon]

do follow the steps in the guide just to be sure

[raven kite]

Isn't there a vulkan to opengl conversion method?

[north quail]

yes but vrr helps smooth out the experience, not just tearing

[lusty talon]

no, it doesn't. like I said we're vsyncing

[neon halo]

you mean the other way around?

[raven kite]

I mean, if someone has a gpu that doesn't support vulkan and wants to use this in opengl games

[cunning copper]

oh so that's why Roblox was forcibly capped at 165 FPS when I tried LSFG on it

[neon halo]

if a GPU doesn't support Vulkan, it can't run LSFG, I mean in terms of raw power that is

[raven kite]

It was the equivalent of an hd7870 gpu

[neon halo]

because that would mean VERY old

[raven kite]

But laptop

[north quail]

got it so if i am running the game with lsfg, i can just disable vrr for that app

[final vale]

why would someone with a GPU like that still want to use framegen?

you cannot even run GTA 5 properly with that

[north quail]

although it's not completely broken, it sometime skip to max fps, when moving around

[raven kite]

It can run doom eternal at low settings 1080p with 60 fps and even cyberpunk at 30 with upscaling and 60 with fg, fsr 3 ofc

[final vale]

720p FSR Ultra Performance + FSR3 FG

wonderful

[cunning copper]

FSR Ultra Performance A.K.A Vaseline simulator

[raven kite]

It was 1080p with fsr quality

I can send you the video

[final vale]

yeah, it looks like shit lol
specially on Cyberpunk, XeSS is miles better

but i assume that your GPU cannot handle it

[cunning copper]

XeSS accelerated*

[final vale]

wdym?

i don't have a Intel GPU but XeSS is stilk way better looking

[raven kite]

https://youtu.be/5rcLg7Xo2rs?si=BSf1_Lwm92oYeitD

What I am talking about is not my gpu tho

I'm asking for a friend

[cunning copper]

nah XeSS unaccelerated is worse than DLSS

maybe the quality preset is somewhat OK to use

but balanced and performance look blurry in motion

[final vale]

DLSS also looks blurry as hell, i've had a NVIDIA GPU once

[cunning copper]

unless you use DLSS performance at 1080p, it doesn't look blurry

[final vale]

can we move to #💭╭・general

[wanton mural]

dont suppose theres a way to build that? Ill do anything to get PSO framegen on linux

[lusty talon]

you can certainly try, but dxvk-native does not have a way to build 32-bit out of the box

clang build times on windows are so atrocious

[north quail]

working fine on windows with LSFG, it's syncing the frames

[cunning copper]

it was an issue on my end specifically with my game. it was a race condition

[raven kite]

Time to troubleshoot @neon halo

[neon halo]

?

[raven kite]

Quake remastered

But now the goddamn stupid discord says there's an update avaible when there's nothing in pacman

[neon halo]

ah yes

proton versions 🙂

[north quail]

just go in
~/.config/discord/settings.json
and add

"SKIP_HOST_UPDATE": true

for some reason.. lsfg-vk perform better then the windows version..

[raven kite]

I already did. It did not work.

And btw, here are the logs for quake remastered

[north quail]

weird worked for me

[raven kite]

I am forced to use vesktop now

@neon halo even with proton base 9 it still does not work

[neon halo]

yikes

[raven kite]

😭

[neon halo]

not that I'm any expert far from it lol

[raven kite]

Two problems today

[neon halo]

but maybe outputting the game session log can help

learned that yesterday

[raven kite]

You think maybe vkd3d proton will work

There logs are these

New ones

[neon halo]

try with this one in Quake launch options
whatever was before the command ending by %command% >> log_file 2>&1

[raven kite]

After the %command%?

[neon halo]

yep

[raven kite]

And where will it store the logs

[neon halo]

near exe

[raven kite]

Well shi

[lusty talon]

@neon halo i had a really stupid idea. you said that on the steam deck in handheld mode nothing worked right?
try putting gamescope around the launch arguments:
gamescope -- env ENABLE_LSFG=1 (...)
no one ever said gamescope within gamescope was a bad idea

😭

[neon halo]

will try 😄

[raven kite]

"gameoverlayrenderer" is this a mangohud problem?

Hold on

It was NOT a mangohud problem lol

[neon halo]

lol the game launches, but there's a spinning steam logo on top of it haha

[lusty talon]

hahaha

[neon halo]

I can hear Trent Reznor

[lusty talon]

try --backend sdl

inside gamescope

Tbh I have no idea what this even means

[neon halo]

Like that?

[lusty talon]

no, put the backend right after gamescope

[neon halo]

This doesnt boot

[lusty talon]

no- don't remove the -- env

gamescope --backend sdl -- env ENABLE_LSFG=1 (...)

[neon halo]

same result than gamescope -- env

game launches but theres a window on top of it

can hear sound but that's all

[raven kite]

I'm gonna try launching the game with vkd3d proton now

Doubtful it'll fix anything but to try

[neon halo]

possible to have --backend wayland
? (nevermind, no swapchain right?)

[raven kite]

Nvm vkd3d won't change anything

I wanna now see if doom 64 runs with lsfg-vk

[lusty talon]

that's what gamescope does by default

so no success sadly :(

[neon halo]

yep, honestly for now it's "okay"
the closest thing people can get which works, is desktop mode, and then big picture

[lusty talon]

ye once I got the deck I'll be able to debug this properly

[crisp scroll]

oh man XD

[neon halo]

but I'd say, don't try to fight gamescope, you will probably loose your energy for nothing, this is something that has to be done in collab with Valve and/or the gamescope maintainer(s)

as a joined venture (I'm sure they'll be down)

[lusty talon]

maybe the article quoting me was right

it is psychological torture

[neon halo]

it totally is

is there an other channel/way for donations?

sadly GitHub doesn't accept paypal anymore 😦

and they're asking for my entire bio or something lol

[raven kite]

@lusty talon doom 64 works perfectly well with lsfg-vk, version is proton hotfix and from steam

[solemn elm]

github has a donation feature?

[raven kite]

It uses the vulkan renderer

[lusty talon]

i don't even know how to feel about almost having 500 stars on this repo

[neon halo]

better get used to it because you're just getting started 😉

[solemn elm]

people have been wanting this for a loooooong while

[lusty talon]

ehehe

[crisp scroll]

yeap :C

[lusty talon]

honestly when I joined this discord I expected a solid 5 people to be interested in this

[neon halo]

the most impressive thing, is the frame pacing, for the rare instances where it works properly, I was expecting stutters, but no, flat as (insert joke here)

[lusty talon]

the current approach works well

I haven't thought about how well it works in sub-par situations

i need to spend time doing that

time that I don't have LOL

[crisp scroll]

any idea native vulkan app i can try :v

i don't have many ideas what do

[neon halo]

Quake 1 or 2, or Doom recent port

[crisp scroll]

ok

[solemn elm]

lol

[neon halo]

if you feel very adventurous, you can try The Talos Principle original in Vulkan mode

since it was historically the first real game to support Vulkan

[raven kite]

I am gonna test if this works with flatpak

[neon halo]

you know what, I'm actually going to download it, I've been pushing away talos principle for the longest time

[lusty talon]

it won't out of the box

[neon halo]

need to play it more

[lusty talon]

see something that's really funny is, I made this program because of genshin, and no other reason

[raven kite]

The moment mangohud didn't work my hopes were crushed 😢

[lusty talon]

i own like 3 steam games

[crisp scroll]

found a playground of old linux games :D

[neon halo]

DXVK was made for NieR automata

[lusty talon]

you'll just have to wait a bit :P

[lusty talon]

lolololol

linux gaming is fueled by weebs

[raven kite]

Will any opengl game work?

[lusty talon]

you can try with zink, but no

anyways im gonna lock back in I really wanna finish 3.1

[neon halo]

ETA need some rest and we'll see tomorrow?

or possible tonight?

[raven kite]

I am gonna test doom + doom 2 real quick

[neon halo]

looking at my coffee machine with affection lol

[crisp scroll]

one thing if kicks the in vkcube must be slower?

[neon halo]

oh damn there's a linux native version of Talos?

that's almost cheating lol

[raven kite]

We can add both doom 64 and doom + doom 2 to the list of compatible games 👍

[neon halo]

Maybe the System Shock 2 remaster a well? 👀 since it runs on Kex too

[raven kite]

I'm ngl it feels so smooth it feels exactly like that mod called smooth doom where all the weapons have smoother animations

[neon halo]

despite my profile pic, I still haven't bought the game lol

no way Talos is even 64 bit!

[raven kite]

Seems like all those old Id software game remasters have a tendency to go in a black screen after quitting lol

[neon halo]

As expected, the native linux build of Talos is borked lol, game boots, but UI has issues

forcing Windows version by selecting proton exp (my little trick)

[raven kite]

So far I haven't tried a single native game

Every native game I have is either too old (such as half life)

[neon halo]

hard to, Proton favors Windows build 99% of the time (and it's a good thing)

[raven kite]

Or just broken on Wayland

For example the metro exodus native version on Wayland is broken and crashes

[neon halo]

that version is obsolete anyway

they didn't port EE right?

[raven kite]

What does that stand for

[lusty talon]

i somehow misread this as IE and I was like "no they didn't port internet explorer 😭"

[neon halo]

Enhanced Edition

[raven kite]

No

[neon halo]

yeah so better translate EE

[raven kite]

And besides the only difference is has is that it uses rt compared to the og

[neon halo]

what's wrong with EE
(kudos to those who get the ref)

[raven kite]

New 3dfx when

black was unreadable in dark mode

[crisp scroll]

well ultrakill working fine

[neon halo]

@raven kite https://youtu.be/UsCe-lawvmE?si=wmDX-mGYORV3WFf_&t=223

[raven kite]

Whats wrong with ee?

[neon halo]

Damn, Talos is obscenely well optimized, it puts to shame a lot of productions out there

man I forgot how obscene Talos was, the number of options is like, 150

the guys are masters of their craft, there's like 8 different anti aliasing options for different things in the game

[crisp scroll]

mangohud can overlay the generated frames by lsfg?

[neon halo]

The Talos Principle (Proton Exp aka Windows Build forced) 64 bit build in Vulkan renderer, confirmed to work as intended with lsfg-vk 🙂

This is the smoothest 30 fps ever lol

[wanton mural]

Alternatively, if i had a fix for gamescope NOT randomly freezing PSO, that would be acceptable.. I guess

I wish I knew why

[raven kite]

Yes

But it's really weird, sometimes it works and sometimes not

[raven kite]

The compatible game list is gonna blow up like crazy

[neon halo]

not too much since for now, it's really only 64 bit and DX12 has been very dodgy, but it's a really really good start

when it works, it works like a dream, as it can be seen

I intended to be more stable while filming, but I was like, no-one is going to believe me that this is locked at 30 FPS lmao

[raven kite]

Imma test it on quake champions

[neon halo]

Skyrim Special Edition 💀

for some reason it runs like total ass on the deck lol

would be fun to see if it is at least possible to generate frames and see them lol

my expectations are not high lol

[raven kite]

Nah I ain't updating this dead ahh game of quake champions

[neon halo]

hey, you, you're finally stuttering

[raven kite]

I'll try wolfenstein 2 although it probably won't work since doom 2016 doesn't and it uses the same engine

[neon halo]

oof nono, Wolf 2 requires a powerhouse

[raven kite]

Black screen 👍

[pine topaz]

heyyy how can I check if LSFG is actually working?

mangohud doesn't show an improvement

[raven kite]

The guide says to memorize the vkcube spinning pattern and if it spins slower with fg it's working

[neon halo]

as for games, well, what's your monitor's refresh rate ?

[pine topaz]

144hz

[neon halo]

might want to lock the game you're trying to test at 36 FPS, and do x4

if it's smooth it's working, otherwise it's not 😄

[pine topaz]

okay I'll try satisfactory

[neon halo]

that or 30 x4 with VRR

I swear if Skyrim SE works well, of ALL the games lmao

[pine topaz]

doesn't seem smoother

[neon halo]

vkcube worked?

[raven kite]

We can add another game

JDM japanese drift master works perfectly fine

[raven kite]

Does mangohud show a fps difference?

[pine topaz]

no

it didn't in vkcube either

[raven kite]

Does the cube at least spin slower

[pine topaz]

hard to tell but maybe?

[raven kite]

Hmm

Have you followed every step in the install guide

[pine topaz]

made a gentoo ebuild that basically does the same thing

[raven kite]

$ file ~/.local/share/vulkan/implicit_layer.d/VkLayer_LS_frame_generation.json (...)/VkLayer_LS_frame_generation.json: JSON text data $ file ~/.local/lib/liblsfg-vk.so (...)/liblsfg-vk.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (...)

Try doing this to verify if the files are correctly installed

If it gives the output shown above then yes

[pine topaz]

I install it to /usr/share/vulkan/implicit_layer.d/VkLayer_LS_frame_generation.json but should still work

[neon halo]

well, I got Skyrim to launch in fullscreen that's a start lol

[raven kite]

Yeah no you should've probably installed it to the guide's reccomended path instead

Still try checking the file in that dir where you've installed it

[pine topaz]

well I'm making a package to make it easier

[neon halo]

A Bethesda Game runs at sub 30 natively
sounds about right!

[raven kite]

I don't find a package really useful, I'd just compile from source

And whenever there's an update I just do

cd lsfg-vk git pull rm -rf build cmake -B build -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=~/.local \ -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON \ -DCMAKE_CXX_CLANG_TIDY="" cmake --build build cmake --install build ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

(stolen)

[neon halo]

@lusty talon wanna laugh?

It works on Skyrim SE

of ALL THE GAMES

[raven kite]

And no doom 2016

[neon halo]

we really need a faster model though, the deck crumbles, but frame generation on Skyrim SE works as intended with properly presented frames

Sorry for the bad camera quality, at least it records 60 fps well 🙂

[patent glade]

How's input latency?

[neon halo]

pretty much how'd you expect 30 FPS base + Vsync to be

it's allright

for a game like this

you're not going to flickshot with an arrow and gyroscope, but it's going to be allright

I'm eager to try 45 base x2 for 90 generated, but that will have to wait for a more efficient model 😉

[patent glade]

Same history behind DXVK, the dev created it just because he wanted to play Nier Automata on linux XD

[north quail]

I am not sure, but on linux there is less input letencu compared to windows lsfg

That what i felt

[neon halo]

probably placebo though, at least VRR vs VRR

especially if we're talking LS 3.2 with QT 0

[raven kite]

Smoothest 60 fps ever

[north quail]

Though vrr works fine with windows

[raven kite]

Hope for performance mode 🙏

[pine topaz]

[Vulkan Loader] ERROR: Error relocating /home/doggo/.local/share/vulkan/implicit_layer.d/../../../lib/liblsfg-vk.so: _ZN4dxvk2vk8DeviceFnD1Ev: symbol not found

[neon halo]

waw

why is it so nested?

/../../../

[pine topaz]

because yes

https://github.com/PancakeTAS/lsfg-vk/blob/a73ce58f9c864c60d47fde6edbd6fb2a2c3943b9/VkLayer_LS_frame_generation.json#L7

[neon halo]

there must be some path replacement or something

[pine topaz]

no

[neon halo]

wait no I'm dumb sorry

it's late

it's 3 back actions in folder tree

yeah path is correct

[pine topaz]

maybe I should disable LTO idk

[raven kite]

You have to first uninstall it by deleting the files you put in your custom directory, and to update run each command individually, not all at once

[pine topaz]

I uninstalled my ebuild

[raven kite]

Alright

[pine topaz]

removed the older LTO build installed in ~/.local/share etc

[raven kite]

Now reinstall it by following the steps in the guide carefully

Hold on

[lethal steppe]

we'll never escape from this scene

[raven kite]

https://github.com/PancakeTAS/lsfg-vk/wiki/Installation-Guide @pine topaz this guide

[pine topaz]

yes

[raven kite]

$ cd lsfg-vk $ git pull $ rm -rf build $ cmake -B build -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=~/.local \ -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON \ -DCMAKE_CXX_CLANG_TIDY="" $ cmake --build build $ cmake --install build $ ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

A more understandable version of my way of updating the project

@pine topaz

[pine topaz]

there's still [Vulkan Loader] ERROR: Error relocating /home/doggo/.local/share/vulkan/implicit_layer.d/../../../lib/liblsfg-vk.so: _ZN4dxvk2vk8DeviceFnD1Ev: symbol not found [Vulkan Loader] INFO | LAYER: Requested layer "VK_LAYER_LS_frame_generation" failed to load. in console when I run VK_LOADER_DEBUG=all ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

to clarify vkcube does run, it's just that the layer doesn't load

[neon halo]

does someone here has the Steam Deck LCD?

[raven kite]

Yeah

I have the 256gb one

[neon halo]

my hero

can you do a command

cvt 800 1280 60

[raven kite]

Try removing vk debug all I'm too tired atp 😭

[raven kite]

Wtf is this

[neon halo]

and copy paste the result, thanks!

just listing the EDID of the LCD display in desktop mode

[pine topaz]

that doesn't change anything

vk debug just shows it isn't working

[raven kite]

I have no idea

[pine topaz]

yep

[raven kite]

Are all dependencies installed

[pine topaz]

they should be

[plush trench]

who tried retroarch? all the cores freeze if ran from the GUI.
but invoking them with
VK_LOADER_DEBUG=all LSFG_LOG_DEBUG=all ENABLE_LSFG=1 LSFG_MULTIPLIER=4 retroarch -L ~/.config/retroarch/cores/mgba_libretro.so game.gba -v
works

[neon halo]

it's safe don't worry!

it's just that those MFs at Valve didn't add 60 Hz in desktop mode for the OLED deck

[pale onyx]

Doesn't seem to work on dolphin emulator unfortunately. Tried to manually preload, launch straight into a rom, tried normally, doesn't seem to work :(

[plush trench]

works for me though

VK_LOADER_DEBUG=all LSFG_LOG_DEBUG=all ENABLE_LSFG=1 LSFG_MULTIPLIER=4 dolphin-emu -b -e TimeSplitters\ 2\ \(USA\).rvz

[pale onyx]

doesn't seem to work. What are your settings?

oh wiat, I dont think opengl would work lol

oops

[plush trench]

yeah it won't 😄

i'm kinda struggling to get it to work with xemu. you can select vulkan as a backend in the video options, but it still seems to use openGL anyway? (info from mangohud)

[pale onyx]

thank you, it works!!

you're goated, but unfortunately I forgot how much input delay ls adds 😔

[pine topaz]

it shouldn't be using opengl

did you restart it?

[plush trench]

yes several times

i get a segfault if i try to use lsfg with it

mh https://old.reddit.com/r/xemu/comments/1kwhm7p/2_questions_why_when_set_to_vulkan_it_still_uses/

i'm using the 0.8.92 build, can you try it out on your side?

[pine topaz]

no I don't use it

I do know technically you could use zink to translate opengl to vulkan & use the layer but idk if anyone's ever done that before

[plush trench]

https://github.com/xemu-project/xemu/issues/2212#issuecomment-2923082227 yeah the gui itself uses openGL, so it won't work without workarounds

[pine topaz]

well I guess you can try that

MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink

you need system mesa that has zink

which distro do you use?

[plush trench]

tried __GLX_VENDOR_LIBRARY_NAME=mesa __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/50_mesa.json MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink LIBGL_KOPPER_DRI2=1 from the archwiki but it still seems to be using opengl

[plush trench]

i'm on endeavouros

[patent glade]

test with glxgears

Put MANGOHUD=1 it should show if it's zink

[plush trench]

nice it shows up zink ye

[wanton mural]

so.. would recompiling lsfg-vk as 32-bit help my issue?

with PSO

assuming i could somehow get it as 32-bit

[neon halo]

yeah I wasn't able to make a single 32 bit game run with lsfg-vk so far

[pine topaz]

what's PSO?

[raven kite]

Does zink work for opengl games yet?

[pine topaz]

I think maybe using wine wow64 you could

[wanton mural]

Phantasy star online Blue Burst

2004 game

[plush trench]

i get the same exact segfault with lsfg+xemu regardless of zink being enabled or not 🤔

[neon halo]

is there a Proton fork of that particular branch?

[pine topaz]

no

it's not a branch is a build time option

[plush trench]

wine-staging uses it by default now

[pine topaz]

basically wow64 runs 32 bits software without needing 32 bits wine or drivers

so maybe it'd fix your issue if it's really related to 32 bits?

[neon halo]

how does that work?

[raven kite]

Wow64?

[wanton mural]

what do i need to do to get lsfg working on PSO

use wine wow64?

[pine topaz]

a wine wow64 build

[wanton mural]

of PSO? its a defunct game. thats not happening

[pine topaz]

no I mean

https://github.com/Kron4ek/Wine-Builds/releases/tag/10.11

a wow64 build like the one here

[wanton mural]

hmm. how to install on fedora?

[plush trench]

just install wine-staging

[wanton mural]

ah

[pine topaz]

yeah recent one should work

[neon halo]

so that'd be using Wine instead of Proton though

[pine topaz]

yes

[wanton mural]

thats fine i dont need proton

[pine topaz]

you can't build proton with wow64 afaik

[plush trench]

yeah i'm curious how proton will handle these wine changes

[neon halo]

Yeah on Steam Deck let's say Proton is quite important lol

[pine topaz]

it's optional

[plush trench]

if they'll keep the lib32 or switch to wow64

[neon halo]

maybe GE will do it

allright, imma peace out!

[pale onyx]

also just curious, why doesn't it support openGL?

[neon halo]

needs to hook on Vulkan at some point

can hook if the game is Vulkan or translated to Vulkan

but OpenGL isn't translated to Vulkan

[pale onyx]

understood, kind of a bummer though

oh god I'm really noticing the frame pacing issues in genshin

hmm, they didn't used to be there I think

we'll that's a problem for 5 am me to find out

I wish I could paly minecraft with fg

without having to sacrifice some important mods

[lusty talon]

same

[pale onyx]

playing without shaders is honestly a game breaker

[wanton mural]

how does wine "force d3d9"? is it just d3d9 native,builtin?

i forget

[lusty talon]

wdym force d3d9?

[wanton mural]

lutris does that to make PSO work

it's called zink

When I test the vkcube, i don't have any problem, but when I use for some game I don't see any difference. I was trying to cap fps with mangohud but I don't see any interpolation.

Btw, thanks for you hard work.

[lusty talon]

i won't be able to help you with this now sadly

[untold jewel]

No problem.

I will follow the project, thanks for this.

[pale onyx]

mght be a silly question, how can I use it with steam games?

[plush trench]

https://github.com/PancakeTAS/lsfg-vk/wiki/Configuring-lsfg‐vk checkout the 2.

[pale onyx]

thank you very much

doesn't seem to work on R.E.P.O.

[lusty talon]

it worked on repo earlier, but when I tried retesting it REPO just crashed, even without LSFG

[pale onyx]

hey wait

same thing here

repo not starting anymore 😔

[lusty talon]

probably repo servers down and this is global?

[pale onyx]

nevermind, I just didnt have proton enabled 💀

[lusty talon]

oh

i guess my repo is brok

[pale onyx]

also, pretty sure repo uses something other than dx or vk

nvm I have no idea what I'm talking about

lsfg just doesn't seem to work with repo currently 😔

[north quail]

ya this should work

[wanton mural]

i tried that but it wont run the launcher 😦

[pine topaz]

I guess I'll just give up, it doesn't work no matter what I do

I followed the wiki down to the very letter

[lusty talon]

@pine topaz are you the person trying to build this project with gcc?
i realize my dxvk compilation relies on pure compiler rng which is precisely why you're encountering this error, but seeing how most people could compile just fine I really don't see why it doesn't work for you.
what binutils, llvm and clang versions are you on? i'll take a look tomorrow

[pine topaz]

I did both

[pine topaz]

well I do have an usual setup

it's gentoo with clang+libcxx

whether it was gcc or clang didn't seem to matter, I've had the error on both

binutils: 2.44-r3 llvm/clang: 20.1.7

had the issue in a chroot with more normal setup too

could be gentoo shenanigans

[vestal belfry]

Just want to say this is super cool. I was working on a similar project, however yours is in C++ and you're probably experienced. I was making mine in plain C as I learned C and I have extremely limited free time between 12H shifts and a family of four. Yours is also a conversion into native Vulkan. What I was doing was working on just modding the display capture and reprojection with Wayland display capture and ffmpeg ot GStreamer. I only ever got as far as program capture though.

I'll probably start focusing my efforts on other projects I want to make, but I'm for sure going to read your code because I'm super interested in how you did it. As I get more experienced I may submit a commit in the future.

Thanks again! I love the passion of FOSS projects.

[lusty talon]

if you could dm me the entire build folder and the error i'll take a look at it tmrw

[crisp scroll]

F

[crisp scroll]

well Car Drift Online didn't work via proton :v

and the steam logs are useless

[vestal belfry]

Once this is of high enough quality to be considered a first release, would it be possible to reach out to either Glorious Eggroll or Etaash to have this merged natively into ProtonGE or ProtonEM?
Of course the original program would still need to be purchased and installed on Steam first, but I think this could be helpful to the normies.

[north quail]

I dont think so it will be merged into proton

because use of proprietary software

wine is an opensource project, and proton too, they won't add something that require you have proprietary application to run it, if it was standalone ya they would have, as of now won't happen

Later on distro can ship it as package so you don't have to build it, that can happen

[vestal belfry]

ProtonGE and ProtonEM are both forks that already have stubs for proprietary software, though the stuff they hook to currently is available free of charge

[north quail]

ya but i dont think it will happen, cause LSFG is not a free software, if it was free they could just do something like NGX_UPDATE or FSR4_Update think, where the dll is just updated to latest version and they can use dlss/fsr on latest model.

[vestal belfry]

I'm at work tonight so I haven't looked at how lsfg_vk hooks the source frame gen, but that's entirely possible

I'm not arguing, just thinking about possibilities

[pale onyx]

would it be possible to make a community made compatibility list?

[clever epoch]

hello all. i've legion go on steam os3.8 and a pc on bazzite. I tried to compile under steamOS and bazzite but since Ninja etc.. are not integrated it was a pain. Do you think a version could appear in decky not immediately but eventually.?? Thx

[thin fable]

hi, how do i test if this works on steam deck? I tried the wiki guide last night but nothing seemed to complie for me lol

[gusty spade]

hi everyone, good morning, do we know if the port works under WSL? if not i wanna give it a try and test it in WSL.

[desert monolith]

Why.

[clever epoch]

you must unlock steamOS , after install clang and ninja for cmake but it's dosn't work for me. I'v some errors when i compil on steamOS

[gusty spade]

why WSL?

[desert monolith]

Why try running a linux port of a windows only program in WSL?

[thin fable]

ok thanks

[gusty spade]

i dont have a separate linux machine, i run everything linux related on containers or WSL

VMs are heavier and collide with WSL

[desert monolith]

Its like if you had a book in english, someone translated it 1 to 1 to japanese and now you are asking a translator to translate the japanese copy for you

[gusty spade]

how do you do it?

[desert monolith]

I jist dont see a reason why

[gusty spade]

i cant follow the analogy here tbh

[desert monolith]

Not like you could "pirate" LS as a Lossless.dll is required

[gusty spade]

where do you run the port then?

[desert monolith]

Why run the port if you are on windows

[gusty spade]

you are making me question my sanity ngl, i got confused a bit. Just for clarification again, im not trying to run it on windows

since i dont have a linux machine im trying to find out if it can run on WSL instead

WSL is not "windows", technically it lives inside the windows ecosystem but the same way a linux VM can exist inside windows

just help me out here and tell me where do you run your port forget about WSL

[vestal belfry]

God's bravest tinkerer

[floral basin]

AFAIK, WSL does not have a graphic environment, so you won't be able to run vulkan nor any graphic app

you can compile the software, but not use it, that's what I think

[winter cape]

I had success compiling it inside an arch linux container on steamos using distrobox:

$ distrobox create --image archlinux:latest --name lsfg
$ distrobox enter lsfg
(follow installation instructions from the wiki)
$ exit

In addition to the dependencies listed on the wiki, I think I also needed to install sdl3

[clever epoch]

thanks I'm a beginner on Linux but I want to get there. i test after work

[gusty spade]

X11 works fine rendering UI apps (sometimes it has issues or freezes) but i know i can open firefox and watch youtube videos for example

ill give it a try thank your time guys

[lusty talon]

i wake up and suddenly i'm on techlinked huh :333

[pliant lily]

Found out about this project because of tech linked

its super cool ngl

[halcyon sapphire]

is there any way to confirm the framegen activated besides visually?

[lusty talon]

you can use a debugger, but other than that I don't know of a consistent way

[halcyon sapphire]

ive tried helldivers 2 and the famous cube but it doesnt seem to change anything

[raven kite]

Spins slower?

[halcyon sapphire]

happend once but was because of high system load

[raven kite]

Hmm

[halcyon sapphire]

im hopping on dirt rally 2.0 to see

just to be sure this is right?

[thin fable]

i successfully got the vkcube thing working on my steam deck lol, but I can't really see the difference between the 2 speeds? 🤔

[raven kite]

Yeah

Btw whenever you run vkcube with lsfg-vk, does the terminal show an output similar to this @halcyon sapphire ?

[raven kite]

Then it's not installed correctly

[thin fable]

📦[deck@lsfg lsfg-vk]$ ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

📦[deck@lsfg lsfg-vk]$ vkcube

mine just says this

[raven kite]

Same for you, it's not installed correctly

[thin fable]

lol i c

[halcyon sapphire]

then what i did wrong, checking with the file command gave the desired output

[raven kite]

Do you have lossless scaling on steam?

[halcyon sapphire]

yes, with the legacy 2.13

maybe the path is wrong

[raven kite]

Is it installed in the default steam game directory or somewhere else?

[halcyon sapphire]

/home/iedi/.local/share/Steam/steamapps/common/Lossless Scaling/
is this right?

[sudden jolt]

BTW, 2x 3x 4x confirmed working with X-Plane 12 on Linux. GPU is an RTX 3070

(native Vulkan)

[raven kite]

Yeah

Still try giving it the dll path just to be sure

[halcyon sapphire]

i did, still nothing

[raven kite]

Huh

[halcyon sapphire]

i should recompile then

[raven kite]

Do you have all dependencies installed

[halcyon sapphire]

im on gentoo yk its harder to translate the dependencies

[sudden jolt]

did you confirm this?

[halcyon sapphire]

ye

[thin fable]

ah those files werent there for me 🤔

how do i fix?

[sudden jolt]

did you run cmake --install build?

[thin fable]

lemme check

[sudden jolt]

in the cloned lsfg-vk directory

[thin fable]

yeh i think i did

[raven kite]

$ cd lsfg-vk $ git pull $ rm -rf build $ cmake -B build -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=~/.local \ -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON \ -DCMAKE_CXX_CLANG_TIDY="" $ cmake --build build $ cmake --install build $ ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

[thin fable]

it installed something from peparse_git

[halcyon sapphire]

im gonna do some vulkan recompiling with diffrent flags and will come back later

[thin fable]

this is what the error code says: 📦[deck@lsfg lsfg-vk]$ cmake --install build
-- Install configuration: "Release"
CMake Error at build/cmake_install.cmake:51 (file):

[raven kite]

Try recompiling it from the start

[thin fable]

alright will do thanks

so it looks like I'll have to install sdl3 as it won't let me get further

[lusty talon]

this is a beautiful font..
as for you and @thin fable, run with
VK_LOADER_DEBUG=all (after you fix your installation)

Its DepartureMono Nerd Font

[vestal belfry]

I don't think you realize just how much this has been wanted or the number of attempts, including myself, people have tried to approach this.

The fact that it's in a functional state is the biggest breakthrough on a path forward. With FSR4 and DLSS4 in the state they're currently in, all we really need is the frame gen, and hopefully some day adaptive frame-gen.

[vestal belfry]

Also anyone know if Mangohud would show before or after frames? I have three days off after I get off this shift and plan on hardcore testing

Or maybe I'll just finish Jedi Fallen Order idk

[tawdry needle]

Mangohud shows generated frames.

[vestal belfry]

Excellent. I should be able to tell the difference. I'll have to see if the framerate lock in mangohud affects the base or generated framerate. If I could x3 from 48, that would be great for frame-timings.

[tawdry needle]

Valheim is 40-60fps on my laptop at 1200p, with FG it was 80-100fps, and felt much better. Other games I've tried have been ~70fps, going to ~120. I've yet to find a game which doesn't work. 😍

[gusty spade]

thats how i found out about the port project i instantly went to check, congrats!!

[raven kite]

I got mangohud to work in quake 4 using zink. Now time to try lsfg-vk

[thin fable]

how do i install sdl3?

[raven kite]

As expected fg doesn't work in quake 4 even if using zink

[winter cape]

sudo pacman -S sdl3

[thin fable]

cheers bro

[raven kite]

Well, lsfg-vk launches with wolfenstein the new order using zink but it's very buggy and broken

Meanwhile wolfenstein 2009 works

[pastel stratus]

It's working on helldivers 2

If mangohud is giving me accurate numbers

[thin fable]

ok so i reinstalled everything, had to install sdl3, ninja and glsslang

vkcube works as advertised

how would i get this working in say, the dolphin emulator?

[flint ferry]

General and Reports are closed

[raven kite]

Why are they private channels 💀

[old flame]

🤷

[tawdry needle]

ENABLE_LSFG=1 LSFG_MULTIPLIER=4 dolphin-emu ?

[sour geode]

Took this for a spin on my CachyOS RTX4060 laptop for Minecraft (via Prism launcher) and it works beautifully, no errors so far.
Still working on figuring it out for Metal Gear Rising via steam through the environmental variable launch options outlined in the github wiki's configuration section, so far nothing seems to change, at least neither steam's nor mangohud's fps values ever go above 60.

[tawdry needle]

Have you got a 60fps cap set anywhere?

[sour geode]

No I don't remember ever setting anything like that, nor any place where such an option would be available in this case.
As far as I'm aware only the game itself is locked to 60 fps, hence why I am trying to apply LS to it.
I use nothing else but standard default proton emulation for MGR (no forced proton version, idk which version it uses by default for MGR), inserted the recommended launch options into the steam launch box and launched the game.

[tawdry needle]

Mangohud can set fps caps, either in the config file, or via Goverlay.

Hmmm.. 🤔

[thin fable]

Thanks and how will i know if it's working lol

[tawdry needle]

Have you tried ENABLE_LSFG=1 LSFG_MULTIPLIER=4 MANGOHUD=1 %command%

[sour geode]

If Mangohud had an FPS cap set wouldn't that also prevent it from working in Minecraft?
Because mangohud clearly shows that LSFG is working nicely there.

[tawdry needle]

Yes. I didn't know how you launched Minecraft, or if you had MH enabled.

[sour geode]

Not yet, but I will try.

[tawdry needle]

Start a game without FG, then with and see if you get an increase in fps?

[sour geode]

Yes I did note above that I use minecraft via Prism launcher.
All I did to make that work was launch Prism itself together with the env args.

[sour geode]

This is what I get still.

[tawdry needle]

😦

[sour geode]

I'll double check magohud's options, maybe I'm overlooking something but not holding my breath

[tawdry needle]

If other games are showing >60fps with MH running, then it's not capped there.

[sour geode]

Yeah I don't see anything wrong here

If I am spamming images too much feel free to tell me to stop

I just wanna contribute somehow as tester

[raven kite]

What renderer does metal gear rising use?

If it's opengl you can try using zink

[sour geode]

I actually had to look this up but I think Directx from what I found?

specifically dx9

[tawdry needle]

Yeah, your screencap states it's using DXVK, so Direct X to Vulkan.

[toxic spindle]

Hello I'm having trouble getting the vkcube to work

[sour geode]

I got that error when I didn't install LS into the default location for steam, might be different issue though

[tawdry needle]

Did you downgrade to the legacy version of LS?

@sour geode https://steamcommunity.com/app/235460/discussions/0/3112521013666754087/ at the end of that thread, is someone getting 144hz - might be worth a try, instead of FG?

[neon halo]

back on track, what did I miss? 🙂

probably not much I imagine, I'll patiently wait for the next push 🙂

maybe I can try to run other games in the meantime, to confirm they work

Having Skyrim SE working flawlessly was pretty surreal not gonna lie

I think it's safe to assume that every 64 bit Creation Engine based games will work too

[raven kite]

Wolfenstein 2009 worked with zink

Wolfenstein the new order instead launched but was stuttery and crashed every once in a while

But that game uses directx, so using zink maybe was a mistake

[toxic spindle]

At the moment I have the latest version 3.1 installed on steam , which version should I check to run it on Linux ?

In addition I will add the compilation logs maybe there is a problem here .
https://pastebin.com/if2feMeW

[tawdry needle]

Legacy 2.13, as per the install instructions.

https://github.com/PancakeTAS/lsfg-vk/wiki/Installation-Guide#obtaining-lossless-scaling-and-lsfg-vk

I did exactly the same 😉

[toxic spindle]

Thank you, I hadn't noticed. Now it works.

[neon halo]

TNO is OpenGL

[raven kite]

Weird because when I tried to install reshade I remember it requiring dx10

Or dx9

[neon halo]

OpenGL 3.2 even, because fuck everyone of us lol

[raven kite]

Hold on

[neon halo]

obligatory flex: https://www.youtube.com/live/N65oiZ2Iylk?si=H02Dloq4xe8ey6s9

[raven kite]

Yeah it was opengl

[sour geode]

That user really doesn't offer much info to go off of, no idea what "google fullscreenizer" is, all I found was some old unmaintained github from 4 years ago, idk how that is supposed to help.

[tidal iris]

is there instruction on how to build this on nixos? beacuse I'm unable to do it.

[raven kite]

Ah hell nah nixos is a whole different breed

[thin fable]

for some reason I'm only getting 9fps on re2 remake 💀

[raven kite]

Do it go smooth?

[thin fable]

no idea why my gpu is that high too lmao

i get a weird warping effect whenever i turn the camera lol

[slate bolt]

lsfg must've been on

[raven kite]

Is it smooth? X2

[thin fable]

Yeah it’s smooth

[raven kite]

9 fps 💀

[neon halo]

a little too cinematic

[thin fable]

It’s kinda laggy in the menus but it seems fine in game apart from the camera movement

[neon halo]

Allirght, remember how Crysis 2007 64bit didn't work

actually it does, but it requires 2 things

1: Proton Experimental
2: you must engage Vsync in the game options!

and that's important, because for example, even if you lock your FPS to 30 and do x2 on 60 Hz and the compositor is tear free, it does NOT count as Vsync

Vsync must be engaged in the game itself, and then, frame pacing will be perfect

So not only Crysis 2007 works, but frame pacing is literally perfect, this is insane

@lusty talon Don't sweat right now on my ping since you're in do not disturb mode, but for later, enabling Vsync in the game engine itself (probably also through the DXVK option if there's no in game option) is mandatory (at least in fixed refresh? phenomenal frame pacing after that).

Resident Evil 2 Remake now works flawlessly on the deck with perfect frame pacing

So it's probably safe to assume all the RE Engine games will work

[thin fable]

I should try this again, is the camera movement weird for you tho?

[neon halo]

no it's perfect, now that I enabled in game vsync

[thin fable]

Damn I think I enabled it too lol

What fps is it running at for you?

[neon halo]

set the game framerate to variable, and lock it with VKD3D_FRAME_RATE=45 (or any other number)

[thin fable]

I’ll try that

[raven kite]

oof

Logs for wolfenstein tno

[neon halo]

OpenGL won't work though

[raven kite]

Yeah I'm trying with zink

[neon halo]

zink tranlslates OpenGL to Vulkan?

[raven kite]

Yeah

[neon halo]

oh that's sick I didn't know it existed

[raven kite]

It says it right there MESA: error: zink: swapchain killed 0x7f49003832c0

[lusty talon]

i gotta try that with genshin as well

[timber mango]

Sorry for the Image Quality but i get this error when i Build lsfg-vk

Im on Steam os Rog Ally x

[gray wigeon]

lsfg-vk does not work in WSL😟

[neon halo]

RIP

yeah someone else tried and had the exact same error

[neon halo]

did you do these commands?

sudo steamos-readonly disable sudo pacman-key --populate archlinux sudo pacman -Syy sudo pacman -S clang vulkan-headers cmake meson ninja sudo pacman -S base-devel sudo pacman -S linux-headers sudo pacman -S glibc sudo pacman -S llvm

I feel like I should ping them maybe ^^

[raven kite]

@timber mango

[timber mango]

The First 2 yes but Not the other ones thanks im gonna Test

[keen harness]

I had same issue and this helped me

After this I had one more issue but chat gpt solved it

[neon halo]

Damn that's CRAZY, on Peripetieta (Unity3D, 64 bit, HDRP), as SOON as I toggled in game Vsync, everything runs perfectly

without it it was horrible

[timber mango]

I did that now but Same error

[neon halo]

did you reboot? (just in case)

[keen harness]

Steam os cant compile , do this with distrobox

[timber mango]

Im rebooting now

[neon halo]

it can, I compile

it was a journey, but it compiles

[keen harness]

I spent yesterday 6 hours with chat gpt on this and in the end i got missing errno.h

[timber mango]

Faild again After reboot

[neon halo]

is your SteamOS special?

like modified in some way or something?

[timber mango]

Nope

Its the official one i have Steam os 3.7.14

[neon halo]

I can only see the hardware difference being a factor... but still, that's really weird, as the hardware difference is really not that huge

it's still AMD etc...

I suppose you do
rm -rf build
in the project folder before re-trying to build?

[timber mango]

Nope didnt know that sorry

[neon halo]

it's fine I didn't know that 3 days ago as well 😄

Pancake senpai told me

It's the equivalent of a build clear in Visual Studio when a build fails, if you're familiar with that

so, rm -rf build and then actually building = Rebuild command in an IDE

[timber mango]

Sorry i just know the basics

[neon halo]

you're good, I hope that it works now 😄

[timber mango]

So i put this command in the Terminal in lsfg-vk and than the Cmake Build command right ?

[neon halo]

this is the whole thing:

rm -rf build && \ cmake -B build -G Ninja \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=~/.local \ -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON \ -DCMAKE_CXX_CLANG_TIDY="" && \ cmake --build build && \ cmake --install build && \ ENABLE_LSFG=1 LSFG_MULTIPLIER=4 vkcube

[timber mango]

Ok thanks gonna try it

[neon halo]

Since Unity3D with HDRP works, I think it's safe to say that most Unity3D engine games should work

I have the impression that, as long as the game is 64 bit and Proton Experimental is being used, AND in game Vsync is enabled, it's going to work just fine.

[keen harness]

Is it better to use proton experimental instead of of ge 10-7?

[neon halo]

can't say, maybe maybe not

but it's sure better to use anything over 9

for this project

[keen harness]

I want to try it with wuva on deck and its working only with proton 10-7 and maybe you now does it work with optiscaler ?

[timber mango]

so if i use tthis nothing happens 😂

[neon halo]

I didn't try it myself but optiscaler should work

[velvet stream]

good afternoon folks! has anyone been able to use lsfg-vk on Ubuntu or Fedora?

[neon halo]

you launched a terminal from inside the project folder?

[timber mango]

yes

[neon halo]

weird

take a screenshot 🙂

[velvet stream]

i've been following the instructions on the github page itself, but always end up getting errors when compilling/building

[timber mango]

ok now your command worked but same error again

[neon halo]

Metro Last Light Redux (64 bit, DX11) works like a charm with Proton Exp and in game Vsync engaged as well 🙂

will try the DXVK option instead of in game, just to be sure

[fast pendant]

Hi everyone! I am working on an AUR package for this currently, and it seems as though installing it in /usr/ doesn't work. Are there any troubleshooting steps I should do and post here?

[neon halo]

that's very weird, I don't know what to say

[timber mango]

Yeah but thanks for the help um just gonna wait for a Release on GitHub or a Better steamos install

[tawdry needle]

Fedora 42 here, working fine.

[vapid sedge]

It says I need to switch to legacy_2.13 branch in the settings of Lossless Scaling inside Steam in the quickstart guide. How do I do that?

[neon halo]

if it's just about using it though, for science (because the current model is very heavy) I can package the SteamOS files

[raven kite]

Go into properties, betas and select legacy 2.13

[vapid sedge]

Got it! Thanks!

[velvet stream]

what did you do different from the official instructions?

(obviously) the packages aren't the same as Arch

[timber mango]

For me its just about testing it. I want to Test in emulators and some Games that i have Like horizon Zero Dawn

[tawdry needle]

Installed the packages listed, and one other that came up as missing during the build.

[tawdry needle]

dnf in glslang glslangValidator were the missing ones

[neon halo]

@lusty talon I have 2 excellent news for our joined birthday
1: as long as the conditions are met (64 bit, proton exp, DX based game or Vulkan native, vsync manually engaged), it looks like you may want to start working on an exclusion list rather than a supported list 😉 everything pretty much works! And frame pacing is phenomenal as long as GPU usage is not reaching 99%
2: the dxgi.syncInterval = 1 command from DXVK can work as a replacement to ensure in game vsync is enabled, can be useful for games that don't expose this option (if DX9 or DX12, the equivalent command will also do the trick)

[neon halo]

is it ok if I give you my built files?

[timber mango]

Yeah that would be Amazing

[neon halo]

I'm still waiting :p

[velvet stream]

the build commans where the same?

i have only compiled from source like once or twice haha 😅

[tawdry needle]

Yes, just sudo dnf in clang llvm vulkan-headers cmake meson ninja git glslang glslangValidator first.

[neon halo]

Discord web on the deck refuses that I share the files 😦

even the official flatpak app

rip

[tawdry needle]

You might need sudo dnf group install development-tools also.

[neon halo]

oh, maybe I did that command too and don't remember 👀

I tried to get all the commands but maybe I'm missing this one

[lusty talon]

:3

[vapid sedge]

I am running Xenia emulator through PortProton. But I don't know how to add ENABLE_LSFG=1and LSFG_MULTIPLIER=2in > PortProton > Open the Settings File. Does anyone know how? What should I add? Or is there another way?

[lusty talon]

honestly the frame pacing surprises me a little. are you exclusively testing 2x?
my genshin reaches a dead stable 80 fps but the frame pacing is unusable

i'll try the syncInterval option though

[neon halo]

I can't really try x3 because the deck is dying lol

[lusty talon]

if I'm reading this right you can simply add
export ENABLE_LSFG=1 into here

[neon halo]

but I will, real quick

[lusty talon]

ye fair

[neon halo]

maybe base 20x3 can be okay

[vapid sedge]

I'll try it.

Nope. It doesn't run, neither on Lutris nor PortProton, which is weird because the vkcube spins slower and installation seems successful. I'll try it on Steam.

[neon halo]

comeon steam deck I JUST want to try x3 😭

[neon halo]

20 x3 perfect frame pacing

perfect interpolation artefacts as well lol

since well, base 20 is base 20

[fast pendant]

Is anyone else experiencing severe FPS drops when enabling FG? I am running CachyOS with a Radeon 780m iGPU, and get similar results on every single game I've tried:
None - 165fps
2X - 16fps
3X -10fps
4X - 7fps

[neon halo]

but the smoothness is perfect
