In multiplayer very low fps for 1-2minutes, then it settles
Can play 2-3 games and then starts crashing
Multiplayer has low fps when joining to game, fps settlets after while. Crashing after 2-3 games.

Works perfect, simply tweak the in-game settings **aided** (not blindly copy-pasted) by some optimization guides on YT based on my HW.
LD_PRELOAD="" PROTON_ENABLE_WAYLAND=1 OBS_VKCAPTURE=1 MANGOHUD=1 game-performance %command%
The game runs OK with standard proton. I've tried GE10 (all of 10 family from 10-7), Experimental (bleeding-edge) and CachyOS, and they all perform OK, but runs better in my hardware with Proton Cachyos.
None of the launch options I've posted are necessary to play, but just my standards.

Game crashes on compiling shaders
Tried multiple workarounds such as different proton versions From what I can see here others are not having issues, it must just not like my card

Tried multiple workarounds does not launch past compiling shaders
gamemoderun %command%
Compiling shaders shows a checkerboard error background without GE With GE show correct background For both I have never gotten past compiling shaders without crashing

Works fine ootb, but Crashes after prolonged Sessions
Crashes after prolonged play sessions, seems to have an Memory Leak
Memory Leak

Runs very well really, when i tried to use gamescope for hdr etc this worked but made the game way more unstable crashing very often.
LD_PRELOAD="" mangohud %command%
Had 1 crash in 3 hours of gameplay
Perk/skills menu occasionally has a white background

Runs great on GE Proton10-10 Nobara 42! Ultra widescreen is supported and no major glitches. EAC does not report any issues as of this post.
Mesa 25.3.0-devel Radeon 6900XT

It works somewhat well
White screen when looking at assignments/challenges screen. Big picture overlay does not work as expected.
I have played with Proton EasyAntiCheat Runtime installed

Схоже що пам'ять відяхи переповнюється й гра зависає на загрузці з кінцями
Швидше за все в мене проблеми з продуктивністю через моє обладнання, 6гб відеопам'яті дуже мало. Дяка разрабам, можна відключити Lumen.

middle mouse button does not work in game (but can be used in layout menu)
Avoid setting PROTON_USE_WOW64 as it conflicts with EAC (unexpected error #1). Be careful with WINE_CPU_TOPOLOGY as shaders compilation can occupy all available cores.

Cannot enable VSync

Is this a linux title?
Works out of the box without any issues.

This game runs really well. Do note that I personally found GE Proton 10-10, and Turning Vsync on BOTH crashed the game for me.
gamemoderun %command%
Lags a bit when alt tabbing for a brief moment.
Occasional frame drops and stutters
Crashes with Vsync On, FullScreen
Proton 9.04 straight up crashes for me at main menu, and the intro videos are colored static. Use Proton GE. I always use gamemode run, but not sure if its needed.
MANGOHUD=1 gamemoderun %command%

perfeito

This game runs terribly, though this does not seem to be exclusive to linux. Disabling lumen improves performance greatly.
Out of 3 hours of playtime, only 1 crash occurred

Runs great, GE proton recommended to allow video files to play, regular proton just shows coloured bars
Game features EAC but is enabled for use on Linux
I've been playing testing this for over a year jumping back n forth between Linux and Windows, performance (at least on AMD) is nearly identical
gamemoderun %command%

Given this is the BETA so far its looking hopeful
BETA related crashes
This review is for the beta, i didnt thinker at all to see first unbox experience. All the performance and related bugs could possibly also attributed to Windows (which im not gonna test) but from what iv seen on the Discord. Player beware before buying things related to the Anti-Cheat could/can change but so far its a playable title.
Runs great out of the box.

Closed beta launches and runs out of the box, small issues fixable by using Proton-GE and Gamescope
gamemoderun gamescope --adaptive-sync --steam --force-grab-cursor -W 2560 -H 1440 -f -- %command%
Frequent screen tearing if not using Gamescope to enable VRR(--adaptive-sync).
Cursor capture issue with Gamescope unless --force-grab-cursor is used. Input sometimes feels laggy as well in either case, but I can't tell if that's a compatibility issue or just the game being in beta.
Without any tinkering, you can get into the game and play, but all of the loading screens and in-game videos are completely broken. (Title screen is just a white screen, loading screens are color bars, etc.) Proton-GE fixed the videos for me. As mentioned above, I was experiencing frequent screen tearing on my 165Hz panel without Gamescope enabled with the VRR flag.

Only crackling during inital shader compilation
On the lowest graphics, game has a significant input lag, which is not enjoyable to say the least. It didn't have any issues starting up or running, though, probably could run OOTB with standard proton.
Hopefully it will be fixed on release/future updates.

Beta working fine under Proton, the game uses Easy Anti-Cheat but the developers have appeared to enable support for Proton.
Had to click in and out of the window for it to focus, probably a one off issue.
Played one match before I had to go, everything worked well.
