Yep. I haven't put much work into finding a fix because it seems to be code related (after working on computers since C64, I tend to trust my instincts). I'm running a AMD 4200+ dual core on a ASUS SLI Deluxe mbd with 2 gigs of RAM. With the 7900 GT video card running everything else I've thrown at it with no problems, I hate to try to "fix it" as it could impact other things I do as well.
Anyway, the stutter on my system is pretty minimal--nothing near a game killer. My FPS reads high 40's in game most of the time. I can live with it.
I have no problem fixing other peoples computers but--for some reason--I hate to fix my own
