Proton-6.1-GE-2

In video playback audio would sometimes lag behind a few seconds

Game is playable, but unstable, crashes after or during loading screens, especially in DLC content missions.

Note that the mfplat dll has to be removed (if you installed it) when using GE proton, otherwise videos will not play, video playback bug fixed by GE or by mfinstall, but they cannot be used together.

Sometimes crashes when processing shaders on startup, check for dead fossilize replay processes and kill them if they are present
