Ok: protontricks 242800 galliumnine03 launch options: %command% -windowed (fullscreen crashes for me) works. If you dont have it you didnt miss anything. It's more of an acquired taste ;)
After seeing the Xaudio2 label I also tried faudio and xact. Out of the box: audio works Installing faudio breaks the audio Installing xact audio works again However 3d still isnt being rendered. Works fine on windows 7 ...
