Overall runs pretty good so long as you set to expiremtnal proton, current stable release of proton seems to cause a major grass/foilage bug
Grass and foilage was glitching a lot, my fix was to switch to proton expiremental, instead of using proton stable.
Use expiremental proton if you get grass/foilage twitching issues.
Grass will randomly glitch out and flicker across the screen.

Plug and Play - it just runs out of the box, even Multiplayer!
There is absolutely no bump on the road. Download the game. Start it. Enjoy it to the fullest!

Flickering grass/plants when running normal proton through Steam.
When running GEproton everything works smooth.

The grass and some pebbles flicker a lot, sometimes the pebbles move with the player camera, but they stay on the ground, it seems to be a shader issue.
I had more FPS in Windows 10 and could play at high settings, now I need to play at medium to have between 75 to 100 fps. But overall the game is playable
The loading times are better on linux, in windows it was slower.

Running medium/high settings gets around 75fps for my specs. Other than flickering textures that appear to not need to be there .
Foliage and grass close to player flickering frequently and quickly. Enough to give a migraine or a seizure. Cannot find settings to fix it.
Playable if you can get around the flickering foliage at close distance.
Runs well out of the box

Set a shader cache of at least 10, and set the maxVRAM launch option to 2gb less than what you have for VRAM

grass flickering
launches in windowed at lowest resolution, need to set everytime
VRAM not being utilizied correctly
frequent stutters until launch option maxVRAM applied
This is an enfusion engine game, so DayZ SA performance tweaks can be applied. Also that weird hex GL variable is a fix I used for indiana jones so I wanted to test for this game (VRAM was also not being utilized) I also set NVreg_EnableGpuFirmware=1 in my kernel parameters, though I believe it's enabled by default on 570

If you can deal with performance degregation, then sure. It is playable. And i've enjoyed playing the game.
Slight performance issues, running on low seems to get about 45-60fps. Not ran on windows, so cannot compare.

Works great :) Proton-ge is not needed, I launched it without also and had no issues. But I usually default to using GE anyway
Ping was not visible in server listing ... Common issue, no big deal. I still think it works excellent.
Highly recommend, fun game. Works fantastic on Linux... Although I see many nvidia users complaining about performance. I have a very smooth high refresh rate 120+ fps experience at native 1440p with a mix of ultra / medium settings. Sometimes hitting 150-160fps if not much is happening. I think it is well optimized.

With low settings & 75% Rendering Resolution works almost perfectly with an average of 50-40~ fps.
Lowered Settings to as low as possible (apart from view distance)
The game sometimes dips for a very quick moment around 10fps~ then jumps back, but its barely noticeable (and mostly happens when you load things).

Heavy artifacting unless you use ProtonGE.
Game is very demanding. Minimum and recommended system specs are very misleading. You need a high-end rig to get good performance without using FidelityFX.

Just don't disconnect from a server
Disconnecting or getting disconnected from a server freezes the game and requires a restart

Needed to set my Screen Resolution via Command Line
In the tutorial the grass artifacts flickered. Otherwise runs flawlessly

Seems pretty good with Proton 9.0 as well. Had to disable V-Sync which would cause spikes every second or so. I initially switched to GE due to spikes so I dont know if there are any other problems with the base. There are some slow texture loading issues, but those go away pretty much the first couple of seconds you are on a given server/game.

If you don't mind playing on low settings and the occasional crash, then the game itself is pretty enjoyable.
Game is very demanding. Minimum and recommended settings as misleading, this game requires much better hardware to even achieve 60 fps.
Game is prone to crashing for reasons that I have yet figure out. This also happens frequently on Windows too.

Using default proton ( proton hotfix ), I still encounter slow texture and models loads when spawning, but it is fixable using Proton-GE. Hardware anti-aliasing works without artefact now, but at the expense of performance I did not observed while running the game on Windows. Overall performance seems slightly worst compared to Windows experience, not a big deal considering smooth and stable performance are not achiveable on both OS at this state of the game developpement.

When switching Fullscreen/Windowed it might get glitched
Look at performance problems
After ~1h of playing itll start stuttering if you give a input, if you stay still/are in a vehicle and stay still there are no lags
Very good game, you might have to restart it every hour or so :(

added the startoption that the game only run on physical cores. newest proton ge fixes all visual bugs, like long loading weapon and scope textures on start
Works flawless

UI is difficult to read, of course

Runs perfectly fine on my setup.
Sure, there are bugs, but those are due to the game and not because of Linux.
Even FSR works perfectly fine.
I noticed that manually installing AMD graphics drivers from their website worked WAY better than the open-source ones "pre-installed" on Ubuntu.
[For some reason, Steam thinks my distro is "Freedesktop SDK 24.08 (Flatpak runtime)" (I've installed Steam through Flathub) even tho it's actually Ubuntu 24.04.1]

Grass texture artifacts
Very occasional crack
Sometimes the grass artifacts fix themselves either by restarting the game a couple times or just by themselves. After that it is playable. I play PVE mostly so I simply ignore the glitching grass until it fixes itself or just restart or rejoin the game a couple times. Evidence (without audio because I was trying the new steam recording and it decided to add heavy crackling): https://imgur.com/a/bR9Hdxm

gamemoderun %command% -cpuCount=24 -maxMem=12288 -noSplash -freezeCheck 10
Game will sometimes crash when opening the map or randomly for no reason at all. -freezeCheck 10
in launch options prevents being frozen for too long.

The grass and stones on the ground kept moving around. It was like they weren't anchored and they were moving all around the map.
No option to select which display to put the game on. I had to window it and then borderless it for it to be on my main display.
Could just be my GPU itself but it even on medium to high graphic settings it was sluggish
Didn't try multiplayer as I wanted to do the training.

Played with Flatpak Proton GE 9-20 for ~40 hours and it caused significant lag spikes when flying on heli, driving or even when walking sometimes, setting Proton Experimental fixed that, I think it's because of Flatpak's cpu overhead. Don't know if setting cpu topology is nesessary. Performance is same as on Windows if not better.
Just works. You do lose about 10% fps compared to windows tho.

Heavy glitching of grass Objects
Hardware anti-aliasing broken
To get rid of the artifacts, a solution would be to restart the game multiple times and always switch from Proton-GE to Proton 8.0.5. At some point, the artifacts will be gone.
