Game after last patches running horrible, performance is bad overall. Unplayable at the moment
gamemoderun %command%
Game was running on 3FPS even on menu
Graphics to low, vsync off, AA off, massively increased mouse sensitivity, remapped ESC to back grip button for menu access.
Now on new GE-Proton9-11 game works smooth on good graphics preset and Quality FSR with 90FPS on my setup

The game did not launch with any proton 8 version at all. Only proton 7 versions worked for me. Revert to 7 if it doesn't launch.
As mentioned in the crash section.
I barely get 60 FPS even though I'd expect well over 100 in a game that looks like this on my hardware. There's also frequent drops to around 1-2 FPS when I move quickly in a vehicle. However, I'm not sure this is due to proton, it might be just the game having poor performance - I don't have a Windows install to test.
Other than the crashes I'm sure are not caused by proton, there are some crashes I think are proton-related - sometimes, loading a save will crash the game and make me restart it. It's not very common, however.

No changes, out of the box it works fine
Install, hit play

Does not launch
gamescope -w 1280 -h 720 -W 1920 -H 1080 -f -U -- env PROTON_USE_WINED3D11=1 %command%
Tried with GE8-20, GE8-3 (as recommended in several reports), standard Proton, and experimental, with custom launch strings as recommended. Game will not launch.

IMO (10/2023) currently unplayable on steamdeck. Tried GE proton and stock. Even with lowering all settings to low the typical framerate was 22fps and sizable input lag. Which bums me out - the game is in EA and hopefully they will do some tuning in the future. The concept sounds great.
(And I'm not someone who usually cares much about framerate - but it was slow)

After patch 0.135 game doesnt run smooth. Using 100%GPU at all time and getting only 10FPS
gamescope -w 1280 -h 720 -W 1920 -H 1080 -f -r 60 -F fsr -- gamemoderun %command%
Games after its update runs 5-10 FPS, before it was running with the same hardware at 30-40 FPS
Game runs 30-35 FPS with FSR through Gamescope on newest GE-Proton8.3 through DXVK on old RX 570 4GB without any additional mods
gamescope -w 1280 -h 720 -W 1920 -H 1080 -f -U -- gamemoderun %command%
gamescope -w 1280 -h 720 -W 1920 -H 1080 -f -U -- env PROTON_USE_WINED3D11=1 %command%
During first run it has sound artifacts, nest run goes without it
(Only on first gameplay) When starting free play, the screen was zooming in and zooming out with no reason during landing sequence, later it works as it should
Some slowdowns during loading game, game itself runs smooth
At this moment, game must run with PROTON_USE_WINED3D11=1, otherwise with DXVK performance is horrible, also I'm running it through gamescope on Wayland and added AMD FSR scaling

Game-specific steam input settings must be off, otherwise the mouse will not work

The game is playable
low frame per second even with low-quality graphic setup.
