This game will no longer work unless adding PROTON_FORCE_LARGE_ADDRESS_AWARE=1 to the launch options. Neither 3.16-9, 4.2-9 or the latest 4.11-1 works without this, tested on two different systems.
On a positive note, the audio is now absolutely fine, mouse still needs to be set to 3200 DPI to be usable (I normally play on 800)
on proton 5-0-6, game runs almost perfectly with no tweaks, but i am getting occasional vertex explosions.

Reproduction
Just play the game and the audio will be having micro-stuttering , mostly speech from what I can tell.
Playing the game with a mouse and keyboard is unusable, unless you crank up your mouse sensitivity to insane levels.
Comments
Other than the previously mentioned issues, the game runs a perfectly smooth 60 frames per second without any dips on 2560x1440.
