Ok, so I fire up Unreal Tournament 2003 for the first time in a while, and it plays like crap; the game is EXTREMELY choppy to a point where it's unbearable. So I try Jedi Knight II and see how that runs. I've never had a problem running this game before, it's always been silky smooth frame rates--but I try playing it now and the entire game plays with horrible choppiness. I figure it's a video driver problem, so I reinstall my drivers, install the newest ones, yada yada yada; but nothing helps. I've tried adjusting all video levels, but it's all the same, even with low quality details and 800x600 rez. I've tried defragmenting, cleaning up the disc drive, RegCleaning, and just last night I reinstalled Windows. EVERYTHING I've tried has not helped at all! Is there something seriously wrong with the actual hardware inside my computer, or is is something simple that I may have skipped over? Please guys, I'm desperate; my computer's running like *** and I have no idea how to fix it
