I don't have it. Runs fine, no stutters and FPS is good. But then, I never had any problem running the software, from June 6 when it came out. Not to say that I played it constantly, but that had nothing to do with the way it ran.
Duron 700, 512m RAM, GF2, no prob. AMD running at 1800, 1 Gig RAM, GF4, no problem.
