%command% -dx11 SteamDeck=1 %command%
Textures on buildings, especially inside buildings were flickering heavily and also reducing the framerate from a normal 130fps to 40-60fps. Issue is fixed by playing in dx11

gamemoderun %command% -dx11
dx12 mode has quite heavy artifacting
Using dx12 mode caused fps to go from ~120 to 60-80
Launching the game with -dx11 launch option gives you a much smoother experience playing the game without artifacts.

gamemoderun %command%
Runs alright with Proton 9.0-4 as well, with some sound crackling in the main menu, so I tried the GE version with some basic launch parameters and now it runs like a dream. I tried forcing Vulkan (-vulkan) but I got shader-related errors and the game wouldn't start. I don't think my CPU would approve trying to run this in DirectX 12 (-dx12) so I just left it as is. Gamemoderun should be helpful for mid-range systems like mine to squeeze out some extra performance (I hope). Using %command% to ensure Steam doesn't ignore the rest of the launch parameters.

It just works.
Linux Mint. Had zero issues with the title.

%command% -dx12
Proton GE really made the difference in loading times and FPS. It was almost unplayable using Proton Experimental for me. Now it flies.
gamemoderun %command% -dx12
runs better than windows 10

Works well
Works well

-dx12
Still works fine with proton9

Ofrece una muy buena experiencia para jugar sin ningún problema en su ejecución.

works
some screen tearing occurs with vsync on, turn it off to fix

Worked Perfectly Out of the Box
I've got my Linux Mint system with no bling, no fuss, and it worked just fine. Overall, really happy.

It Works Again
This game broke for several months (very aggravating), but is playable again with no tinkering. I still have the Steam overlay turned off for this game, but I don't know if it's still necessary.

Overall solid
Some updates break the anticheat-proton compatability but other than this (which occurs very rarely) one of the best running games on linux via proton.

Works with the new update. EasyAntiCheat bug was fixed for Linux. Stable 130-140 FPS on max settings on 1080p
There are some minor artifacts sometimes, maybe due to forced dxvk_async?
*Anakin voice* It's working, it's working! ** No more EAC disconnects. Thank you <3

With the default Proton version (Hotfix), Proton 9 or Proton GE, the game crashes at startup and displays a UE4 engine crash report. The game runs perfectly using Proton 8 however.

Now works out the box
For about a year I was required to use an AUR package to patch glibc for EAC to work, this is no longer necessary

I generally use Proton-Experimental for all my games so i can'T speak about any other Proton Version. But finally the game runs fine and there are no more issues due to EAC. Personally i'd say it runs much smoother on Linux for me as it did on Windows. I hope it stay that way and the EAC BS doesn't come back again. But so far it has been a great experience.
changed to experimental
Runs great. I had issues when I installed kde plasma instead of gnome, but now I'm back on gnome and it runs fantastic.

gamemoderun %command%
Latest update has fixed the "EAC Unexpected Error (#1)" error message. It runs as normal now. No issues at all on my hardware & can play online just fine.

There is no issue running Insurgency Sandstorm.
Just a few FPS less than on Windows with the same hardware
A few days ago there was anti-cheat issues but that was resolved quickly.

EAC problem has been fixed since my last report.
Game is running well just as before the update.

EAC issues from the 1.17 update have been resolved
After an issue with the 1.7 (?) update, the game is back to running on Linux.

install Proton Battleye in Steam and works. its very strange. Sandstorm used EAC

SteamDeck=1 %command%
Working without issues. You may try the SteamDeck=1 env variable in order to make it work (even in desktop).

Working perfect.
There was an issue after game update with the EAC (1.17), but it looks that everything back to normal. Looks that it was something on their side (i didnt update any packages in my OS).

Anti-cheat Broken
Anti-cheat doesn't work again.
You used to be able to trigger an update to EAC by validating local files, but that trick doesn't work now. I already went through the hassle to run this game by installing Steam in Flatpak. That worked for a while to solve a different problem. I am just torturing myself at this point trying to play it. I have 217 hours. It was fun for years. It's been aggravating and unreliable for many months now. I'm mad.

Game was working perfect before latest update (1.17). I was tested few Proton version including GE one. EAC still not working right.
Getting kicked from the server after a few minutes. "Kicked from server: Anti-Cheat: Authentication timed out (1/2)"

Multiplayer non-functional due to EAC error w/ latest update
DXVK_ASYNC=1 PROTON_NO_ESYNC=1 gamemoderun %command%
Ever since operation Resurgence (update 1.17), am kicked from multiplayer servers after about a minute or two. Error reads: "Kicked from server: Anti-Cheat: Authentication timed out (1/2)". Should be noted EAC-compatibility does regularly break with updates to this game, so is not a new occurence.
Singleplayer fully-functional, and all good otherwise

none
Can't play the game online since 1.17 update cus of EAC. I hope to find a solution quick.

Anti Cheat timeout after last update, about 2 minutes after joining a game.

As of the current update to the game (December 7), I can not play the game for more than a few minutes without getting kicked out with a mesage: "Anti-Cheat Authentication timed out (1/2)". Before this update everything worked perfectly.
Anticheat has been broken since the last update - player gets kicked from game after a minute "anti-cheat authentication timed out 1/2"
PROTON_USE_EAC_LINUX=1 %command%
Playing online will result in getting kicked out by the anticheat (authentication timed out)

Getting kicked from every server after a few minutes. Message: "Kicked from server: Anti-Cheat: Authentication timed out (1/2)". Single player works fine.

El juego a dejado de funcionar
Antes de la actualización que se lanzó el 5 de diciembre, el juego corría bien y sin muchos problemas, ahora no puedo jugarlo ya que me aparece un error que cierra el juego.

New update broke the anticheat
It used to work flawlessly, but now it boots you with a "Kicked from server: Anti-Cheat: Authentication timed out (1/2)" message
