oh man wasn't expecting this to really work!
i literally got an extra 15fps in the snow level
, without losing noticable quality
before i had to play on 1024x768 gamer settings, but now i'm playing on 1280x1024, enthusiast, no aa, very smoothly! i don't have fraps running, so i can't give an exact number, but it sure looks nice! i'de say 20+fps?
and no more jerky motions!
just ran fraps, getting a constant 31fps
btw, i'm running vista 64bit, 8800gts 512mb, amd x2 6000+, 4gb ram. all stock speeds
yay for this config!
