In the original game, if you turned Vsync on, the game would be locked to 30 fps. Is this bug fixed in the GOG version, ie. can I run the game at 60 fps with Vsync on?
Alright, the best option I found was using D3Doverrider for Vsync force and Msi Afterburner, then turning off Vsync in game & limiting FPS to 60 in RivaTuner Statistics Server. Now it runs like a dream, just the mouse crapola which I solved by just turning down sensitivity..
Also, hint for AMD/ATI users, DO NOT use Radeon Pro to tweak this game, Dxtory is fine instead of MSI afterburner, but Radeon Pro can lockout your access to your desktop in fullscreen mode, in a weird glitch that might require a logout or reboot to get out of.
