I think you guys are right. But I wonder why Windows Update in Windows XP doesn't detect that I need new video drivers - isn't it supposed to do that for me and download them automatically?

It must be the video drivers. You guys must be right. I've tried changing desktop resolution and refresh rates, I've tried making sure no programs are running in the background, I've done everything else I can do. Besides, it's not just TSF that has a problem, so that rules out any possibilities that it's something to do with the game.

Okay, I'll definitely check out those detonator drivers. I'll let you know what happens too.
