Ran OOTB, no issues at all

Game runs at 90fps at 4K high settings with my hardware and 150fps at 4K lowest settings - could be that the game is just unoptimized.

There was a small issue with voice chat but was only temporary it seems on the first run. After that, all was fine.
Nice simple and easy game to run with very little/no need for tinkering.

Works perfectly

SDL_AUDIODRIVER=alsa PULSE_LATENCY_MSEC=60 %command%
My system uses pipewire for audio. I was unable to use the in-game voice chat until I forced the game to use alsa for the audio driver. The audio was then choppy until I added the usage of the PULSE_LATENCY_MSEC=60 as a launch option.
The in-game voice chat does not work with pipewire without using the launch command to force the game to use alsa

Runs perfectly once you put low settings and GE-Proton9-21 docked 60+fps

Just added jump and crouch to back buttons.
slows to 40 fps every once and while, but runs just like windows otherwise.

Its works very good <3
