I have a 19" Envision EN9110 (DVI) and I get a perfect screen at 1024x768 while its native res 1280x1024 give me the weirdness. I have Monitor Scaling selected in the NV61.77 drivers. -- McGrandpa [AGQx] > > Next problem - the game runs well for about half an hour or so, and > then slows right down (big pause when you enter a new frame, > jerkovision even thought the reported frame rate stays high etc.). > Its easy to fix, I just need to quit from the game, re-start it and > go again for the next half-hour.
