I tried running under GE-Proton10-1, but the videos didn't load. After trying a few Proton versions, I managed to launch it under 9-3 first, but encountered some stuttering. GE-Proton9-10 worked well enough.

32-ish hour playthrough of full game, no crashes, slight audio problems for which I described possible cause / workaround.
With the in-game tactical pause (shift) I had crackling sound problem on my Radeon card, which seems to be mostly solved by keeping the in-game FPS limit turned off (it's off by default). There are reports of this problem also on Windows.

On buildin graphics this runs smoothly. Sure, only low details on full HD, but still impressive.
It just runs

Very good gaming experience on Debian Testing (DEMO version !).
switching to overview mode in KDE an switching between windows took very long and sometimes did not work at all

Hangs at intro scene
This is for the Demo version. Game launches successfully and you can click new game, but shortly after the voiceover starts the game just hangs and the system becomes unresponsive. Trying to get out of the game does not seem to work with the only 'safe' way of getting out being with the Magic SysRq key.
