Crashing and severe performance degredation when playing on modded servers (W.C.S). I am unable to play for more than 10 minutes before the experience becomes unplayable

Only the FIST start of the game it was "sluggish" but after the first start up everything is fine.
First time starting it up it was sluggish and the game had the wrong display resolution. But that was easy fixed in-game dispay settings.

No tinkering needed, it just works as it is in Windows. Performance is so far comparable to the Windows except the sttuters
Sttuters is occurs, but this game is just bad optimized.

Once you can increase the Vram from 1G to 4G and then adjust the in-game settings to medium, you get 30-40fps on single player.
when exiting the game, i get a crash report occassionally.
Amazing game

It runs flawlessly straight out of the box.

Worked OOTB
Didn't change any settings just downloaded the game and launched it. Was able to launch into the tutorial and multiplayer without any issues

echo "%command%" | sed 's/ArmaReforger_BE.exe/ArmaReforgerSteam.exe/' | sh
NVIDIA users should expect graphical glitches, specifically flickering grass textures. There are workarounds for this glitch. Game runs well OOTB on AMD GPU's and users should expect little to no fuss.
In most cases, game will not load without the tinkering setup provided. It will launch then instantly crash without warning.
Arma Reforger is typically buggy from the get go ESPECIALLY with mods, doesnt matter what platform you play it on it'll always have it's issues but setting it up with the custom launch options I have put down, it's as good as it can get. The game on Ultra graphics is not worth the performace dip as high looks equally as good and you can get playable frames (25-40FPS while near or in battle). All & All, given it's bugs, it runs as good as it does on Windows from my experience & multiplayer works as good as it does on Windows.

Heavy grass flickering
With KDE Plasma fractional scaling game will not register courser input properly if you change the ingame resolution
You get ~60% of the windows performance with NVIDIA
Game is buggy all the way, constant server desync, gamebreaking animation glitches, phantop supplies, etc...
Unless you have a real beefy PC with an AMD GPU you should not play this.

Works perfectly fine with 40 fps, some freeze when joining a server but its also like that on windows. With Ultra Graphism
had some problems with the grass flickering , but after a reboot of the game it got fixed, maybe it was a shader that loaded incorectly.
Didn't do any tinkering, only launched with GEProton10-7 and worked fine.

Good if you have an AMD gpu or apply the workaround below, but by default, if you are on nvidia the foilage bug renders the game unplayable
Very disruptive grass flickering bug, apparently only prevalent on nvidia GPU's
Uncommon freezes, and rare crashes sometimes
Workaround for nvidia users here : https://github.com/HansKristian-Work/vkd3d-proton/issues/2031#issuecomment-2990994647 , only requires a config file edit to fix.
Other than that, the game is decently stable with very few freezes or crashes.
Still, i would definitely NOT consider this game as "gold" rating, mid-high silver is where it really should be at.

Playable with some minor annoyances, flickering textures and slightly lower performance than Windows

I used a pyroveil config from this GitHub reply, which made the grass stop flickering: https://github.com/HansKristian-Work/vkd3d-proton/issues/2031#issuecomment-2909008780. You need to compile pyroveil yourself and make a shader dump in the game's root folder (noted in pyroveil read-me), but afterwards it is really playable with no flickering or artifacting.
Grass flicker around 100% GPU Utilization

If you grass is not set to the absolute minimum 60% of the launches grass will start "flickering" all over the place.
Inputs are broken in fullscreen with KDE Plasma with fractional scaling.
You get half of the fps you get on windows.
It crashes, but it is not Linux specific.
It lags, game itself is unstable, servers themselves are lagging and crashing quite often. GTX 1650

If you have been having the same problem please use launch options as provided, I don't 100% know why they work but they do.

45-60 Mins of gameplay, it would become unbareably laggy but still high fps (140-200) please set launch option provided to fix problem.
WIll disconnect from server every now and then.

In editor mode everything is stable, but when I go to any server, after 1 minute the game hangs (long wait doesn't help). I could not solve the problem

It works now
No monitor options, starts on wrong screen, needs to be forced through kwin
No more foliage bugs, no more low framerate. It just works like on windows now.

Almost there
The extreme flickering on foliage is still present
As of the latest patch, the performances are exactly the same as on windows. The extreme flickering of grass/foliage is still present.

They actually fixed a texture bug that was plaguing the game on linux! It runs good on Hotfix and GE-10.1. No fuss, even with mods!
Buttery smooth, but this game shows my 3080's age. At 1440p, it needs lowest settings and no contact shadows to hit 100-110fps, and 60-80 with medium settings. Ultra is playable but harsh on the system, especially with mods.

Same performance as in Windows 11. Both vanilla and modded servers run without crashes or other problems.
The only thing are the stutters that my Windows friends also have at the same time, but that's just the game

Crashes when playing modded servers, runs great in vanilla
Runs better than windows in vanilla. When adding lots of mods for modded servers, stability decreases by a lot. Had many crashes and freezes on modded servers. Have used proton-cachyos and regular experimental bleeding-edge and had same issues on modded servers recently.

-noSplash
stuttering after 1 hour of gameplay
Overlay had to be enabled to fix stuttering after 1 hour (or so) gameplay.

Works but has very minor issues
Issues including map icons not flashing when enemy is capping (visual queues are missing but some text able to help identify)
Additionally in multiplayer menu there is a lack of PING numbers or rating to help identify assets.
other then some basic microstudder when loading into the game, and a BIT of a sub preformance to windows it functions just fine, and is 98% playable in that context. Even modded content.

Setting Proton to beta 10.0-1 fixed the grass artifact issue
As long as you switch to Proton beta, the game runs great! Would recommend

Heavy flickering of foliage and grass
The game runs very poorly compared to windows on my 4080 super.
Arma reforger fixed all the former performance issues on windows... and re introduced them on linux. First person combat is obviously not playable if you get a massive performance hit.
Graphical artifacts are an issue. Even more so on a milsim with long ranges where you are expected to hide and spot properly. Sadly unplayable as it stands.

Hold key did not worked (Hold R to inspect radio did not worked)
win10: ~ 40 fps bazzite: singleplayer scenario: 30 fps W.C.S. moded server: 15-25 fps
Does runs out of the box Does support mods: succesfully joined and spawned on W.C.S. modded server

I noticed a little bit of imput lag in my mouse, I think disabling window compositing may help. Also I sometimes get some frame drops, if I play at 60fps it can drop to 50fps at some moments.

The shadows feel artifactey on lower settings
The game seems to start on an active window, instead of my primary screen
The FPS runs along 15-60, has a tendency to crunch the longer I play, but it's gotten better since 1.3 update

Very poor performance on linux compared to windows.
Pretty much unplayable on my hardware. On windows i could get 75+ on high-ultra, now i get 30-50 on lowest settings.
Occasional crashes and stuttering

Audio frequently cracks especially around louder noises like helicopters. This also causes near-crashes.
See audo notes
Reforger must currently be ran on forced Experimental in order to avoid heavy foliage artifacting.
Sometimes fps go to 7fps after only restarting the game problem fixes it self

MANGOHUD=1 %command%
Unsure if Linux issue, but textures are sometimes horribly slow to load. The game runs fine once all the textures are loaded in properly.

With some tinkering, very playable. With no tinkering, can end up terrible experiance that gets worse with relaunches

Heavy Foilage flickering IF there was a desync between FPS and screen refresh rate(or an even division of?), limit to 30 fps then no flickering as long as 29/30 fps maintained, same with 60 fps if maintaining 60fps or very close to it. Issue gets worse with relaunches without restarts(but can still avoid with above, but it might seem like issue goes away when you restart/change proton versions/etc) I assume its a shader thing or something cached that contributes to issue? Monitor "Adaptive Sync" will also cause terrible screen flickering when capping ingame refresh rate to 30fps, turn off to avoid throwing up.
The severe FPS stuttering you might get after an hour of gameplay, tied to mouse movement, can be dealt with using this in steam launch options: env LD_PRELOAD=""
With all of the launch options I have, I still get a crash after a few hours of gameplay. I have not tested if relaunches lower the time between crashes (but this was a previous issue I noticed with a different setup, decreasing time between crashes)

This game is great, having a lot of fun with it even though I keep having to restart every hour (though this seems like a game/driver issue)

Typically there is some audio artifacts when playing in a game, but it seems to quickly go away.
This seems to be a problem in the base windows version of the game according to discussions similar to https://steamcommunity.com/app/1874880/discussions/1/3458219850119073199/ so I don't think it's a proton issue. It could be a driver issue though since some people don't experience these stutters, and I don't think I did when I was playing the game on windows 10 with the 570 drivers.
Drops to 10-15fps after about an hour of playing (might be map related), otherwise it runs at a smooth 150-125fps on 1440p with 85% scaling on medium settings.
Flawless in my experience

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!

When running GEproton everything works smooth.
