The performance and look are horrible no matter what version i try. I sure remember running this beautifully on my windows xp sp3 machine but now in Windows 7 Ultimate is a true hell to just get it working. Any help would be welcome.
It sure is a lot easier and stable with KeeperFX even though it has its own few share of problems like screen lock and crashes.
Also no idea if the GOG version supports VSYNC whatsoever since the stuttering is everywhere.
