Right up until the point were you BSOD with an IRQ_LESS_OR_EQUAL STOP error, because the drivers you're using are different from the drivers the developers were using, and nVidia decided to fix the bug the game relied on. Do you think there's a reason it's customary for game developers to specify which version of the nVidia Detonator drivers you need to use?
Aye, which Nvidia owner can say they haven't had to deal with that a few times?
