I just bought Star wars knights of the old republic II and it lags at some parts. Now this wouldn't be a problem except that I have a new computer. I have a 3.0 gig processer 50 gigs memory 516 ram ATI RADEON 9250 256 MD VIDEO CARD... I don't get it, any help? It even lags at a few parts on the lowest settings! I'm using an older moniter, bout six years old.. Could the refresh rate have anything to do with it?
