Yes. I actually did it a while ago to solve a problem with a different game. It did actually work for the other game, but not this one. Could be some other hardware I have, because on both of these computers, the only difference in hardware is that one has the HD2600 card, and the other has the x1550, mobo, cpu, memory, harddrives, and everything else are the same. So it's possible that it is the mobo or something.
Actually, my brother has the same computer as well with an x1550, and it does it on his too. So there is something common here. Not sure what it is though. They are all ATI, so I figured it was just ATI, and that it is perhaps more compatible with Nvidia.
