The game runs well on both my systems (ryzen desktop/intel laptop), Hovewer the 11th gen Intel CPUs require 'OPENSSL_ia32cap=0x20000000'
OPENSSL_ia32cap=0x20000000 %command%
The game sometimes crashes. I believe it's a game bug.
The game has many bugs per se.
Great game with many bugs.
OOTB no issues with gameplay.
Cutscenes do not play and are replaced with a test-card screen.
Without mf-install, I was able to run "prologue", but "new game" would freeze when it was time to start the intro cinematic.
The only way to get intro working was the latest Proton (5.13) plus mf-install script. It wouldn't work with any of the older Proton versions, with or without mf-install.
The game feels a bit sluggish at times, especially during cutscenes, but it's playable.
Worked fine for me in Nov 2020.

The main game itself runs fine, but no videos will play. Which means that the game cannot be played further than the short intro. Then a video starts and - due to not being played via Proton - never finishes playing and so the game can't advance.

Use newest proton beta, with 3.7-8 the game does not run

Well, technically everything seems to work, and at minimum settings it's just about almost playable. Performance is real, real bad though.
