Here are my specs:
Windows 7 RC 64 bit
Intel i7 920
NVIDIA GeForce GTX 285 using the 190.38 drivers
I get graphical glitches (see below) accompanied by a massive gameplay slowdown and occasionally the graphics will "smear" as the old frames aren't erased as new ones are added. Anyone else have this problem and maybe know of a solution?
Edit: Just a bit more info, this occurs on all graphical settings and resolutions, although it seems to require more geometry on the screen before it does it at lower settings.
