when i first tried it didnt work but all i had to do was update my nvidia drivers

Game runs perfectly I played mostly on windows until I switched to arch linux and the game runs exactly the same except with a small performance boost and no more lag spikes, I have to reselect my microphone in the settings when I start playing otherwise it doesn't work, it seems like an issue with the game itself since I had the same problem on windows

mangohud %command%
Vulkan gives the worst performance for some reason (~33% worse than DX11/12). DX11 and DX12 options give comparable performance, but DX12 has better 1% and 0.1% lows.
Slight VRAM leakage, sometimes causes unity crashes, seems to happen on windows too to some extent (crashes only happen during prolonged gameplay)
(friendly reminder that this game is not very optimised, not good hardware will struggle)

One of the last updates must have fixed it. No more stuck on initial installation script. Runs great with Experimental now.
Even though the opening window of the game says that proton is not officially supported, it works great compared to the previous version.
Sometimes you need to disable and re-enable fullscreen to get it to work, though I believe this is just a wayland issue because the same happens with native Counter-Strike 2 for me.

Its great but before i could play i had to disable adaptive sync due to the screen going black when the game launched or when i had the window open

The correct microphone is selected by default, but doesn't work until I deselect it and reselect it in the game menu. (I'm using PulseAudio).

Works perfectly on latest Proton
Selecting DirectX 12 in the video settings give overall the best performance.

Sometimes on launch it would refuse to launch with error saying something like "Verify files integrity", but few tries rather fix it.
This game works as good on Linux as on Windows (badly as always), depending on amount of players on the server you will have great experience or very unstable. But this is the game's issue.

Works very well without problems
Simply press start and have fun!

gamescope -W 1920 -H 1080 -f --mangoapp -- %command%
changed API to vulkan, gives more stable menus, spectator mode, and textures, but in game performance is almost the same
Cracking with DX12
Missing textures with DX12
On default settings: 5-16FPS, compared to 40-60FPS on windows
Sometimes crash on game startup or exit fullscreen

Shadows and lighting are a bit broken
ALT+Tabbing breaks completely, takes some effort to go back to the game window if it was collapsed
crashed only one time
It works

too slow compared to windows
a lot of missing gun textures and some artifacts
crash at minimize
3-20 FPS compared to 50-70 FPS on windows, default presets
huge loads of models crash the game, cant check
not work tinkering, tried before and nothing hanges
Works like on Windows

LD_PRELOAD="" gamemoderun %command%
Slight stuttering from supposedly poor optimization, but not affecting game experience much.
I (hopefully) fixed a stuttering bug that makes the game stutter every input by adding LD_PRELOAD=""
to the launch arguments

gamemoderun %command%
At some point the game will start majorly stuttering on every input, and I could not find any way to prevent this. A game restart is needed for stuttering to stop, which I recommend doing after every round. I tried different proton versions but the same problem persists.

The game just worked as it should
The game runs slow on the Maximum settings when outside on an RTX 3090 but I had the same whe trying on Windows, this game is just crazy demanding on hardware

gamemoderun __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia
Was really bad at times
Definitly had a lot of audio problems, no visuals, just audio

Because everything worked fine I think a typical gamer with a pc that can run games on higher quality would enjoy it pretty much
I reset the games config files and tested everything and looked for the setting that broke it. I found out that the crashes would occur when I set Graphics API to force Vulkan so I set it to auto which workes fine for me
My Hardware is not the best so it even lags on windows on lowest settings

Recent update broke it
Gets stuck on the installation script, looks like it's launching then crashes

some update borked it
-force-vulkan
asks to delete a file in its plugin folder. tried manually and through the automatic script
if you delete the file manually and run it through wine from its .exe file the game opens but no play, settings, etc buttons appear. if you run it through proton, it tries to execute a install script forever (irrespective of proton version).

Game gets stuck at initial installation script.
tried several
Tried 9.0-3, Experimental, GE-Proton9-16. Nothing worked. Steam wasn't able to uninstall. Had to delete the folder and the appmanifest manually. Borked
Got stuck at the installation script
Could not get past the installation script
Unable to get past install script

WINEDLLOVERRIDES="SL-AC=n,b" %command%
Some stuttering but can be related to my bad hardware and game overall bad optimization
The game simply wasn't launching without any tinkering

Mouse movement is sometimes spontaneously smoothed/slow after long play sessions
If I tried opening another game (steam or not) on Windows, SL would crash. That doesn't happen on my Ubuntu system! So in a way, it runs better than natively on Windows xD

-force-vulkan
As of Oct 27 the 14.0 Patreon Beta works perfectly

Only issue encountered was on the first startup, when the default resolution was 1024x768. Very easy fix by changing it in the settings.

The older reviews drag down the score, it should be gold-rated easily if not platinium
Runs just like windows, I recommend using Vulkan for the graphics API.

some guns are missing textures
crashing on certain resolutions
10 to 20 fps, compared to 60+ on windows
crashes sometimes
needs to tinker and low quality

Proton 9.0 seems to be a little odd, sometimes the game won't launch. Proton 7.0 seems to be more stable.
DX 12 translates faster, as mentioned in my last report.
Small correction compared to my last report.

Pretty much just works out of the box.
Slightly worse then windows, use DX 12 (which translates better into Vulkan).
Using Proton 9.0
