The default steam proton does not work for me. The game would not launch without GE proton.
Pressed launch using Proton Experimental and the game appears to work perfectly
PROTON_USE_WINED3D=1 %command%
Rename/remove file steamapps/compatdata/485980/pfx/drive_c/windows/syswow64/openal32.dll
and install openAL when game ask it
Played with Proton 8.0-1 and params PROTON_USE_WINED3D=1 %command%
and openAL reinstall.
proton 5.13
With Proton 5.13-1 the game itself runs perfectly playable. The game has some stability issues but they are also present on Windows.
Sometimes on launch the game will not respond to mouse input, restart the game when it does this.
sound issue
music only. sfx missing
Only music, nothing else (no firearms sound, engines, etc)
You cannot Alt-Tab at all, or else the game's mouse will stop working.
All dialogs dissapear instantly, you can only read them in Windows.
No sound FX, only music. It totally breaks the game for me.
No sound fx, only music
all is well, only there are no sounds.) Only music.
Game crashes when boarding the second vehicle, every time.
Game runs but crashes after several minutes.
Game starts with all sittings set to high, runs smoothly, but totally crash 1 minute into the first mission.
