We once talked about settings that we are using to play the game, and so I wanted to lis them what settings we are using, and well I wanted to give it a try and test different kind of settings.
So share your settings and the errors or other thigs that are happening to you while playing on this settings.
EDIT: Run game with compability mode Windows XP (Service Pack 3 - Apparently Windows XP with Service Pack 2 fix the audio APPARENTLY) and as a Admin, and use the "best know" settings setting thats we found.
If this doesn't give you constant 60 fps, try enabling HW Vertex Processing. It helped me and few others people getting constant fps.
THIS ARE OLD AND OUTDATED SETTINGSD, not sure if will work for.
So thats mine settings
Only thing that is bad, after credits in any% I got the "No Memory" error, and while 100% game crash while using last tripple elevator just before final boss with the same "No Memory" error.
Here are some other settings that I found, and are claimed to work perfectly (WHO KNOWS) or at least work good without any speed ups, or audio / video de synch
