No crash during non interrupted ~6h play session but some microstutter began. Seems to be problem with the game itself not with Proton.
Ran fine out of the box
Occasional crashing, but that seems to be a problem with windows users as well, Also the intro cut scene looped the first time I started, but has not reoccurred.
Beside some crashes at the initial loading screen before entering the map the game runs quiet well.
While loading an Offline or Online game the game crashes quiet often. But after it has loaded (try several times) it runs pretty welll.
Using PROTON_USE_WINED3D=1 as launch option will reduce the amount of initial crashes but will also introduce heavy graphical degeneration. Missing textures, shaders, poor performance and red flickering at the horizon.
cyan and black textures where water or blood should be. Red flickering in the distance.
Only works win PROTON_USE_WINE_D3D=1 DXVK will crash the game constantly
Crashes only with DXVK but not Wine D3D
