Im gunna cross post what I just said on the ATI forums, maybe you guys can help:
Ill start with my system specs:
GA-P55-UD4P mobo
Intel i5 750 CPU
Sapphire Radeon HD5850 gpu
4GBs Gskill 1333
Ever since I got this card and the free version of Dirt 2 that came with it, Ive been having odd issues in Dirt 2. Instead of explaining, Ill just link to some pics and video:

http://www.youtube.com/watch?v=BLQmxwRvQUQ (Video of me just driving around to show the errors, ignore the framerate. It got wonky once I started recording. Sorry for the bad quality, you can really notice the issue around the 20 second mark)
Now turning crowd detail down to high or low practically eliminates any issues with the crowds but I cant get rid of them for anything else. I cant find anything on a google search either.
The only other game to show these weird issues was The Witcher but that was fixed back in November with a driver update and hasnt shown me any issues since. Crysis, Crysis Warhead, Titan Quest, Torchlight, UT3, and Mass Effect all run and play amazing. Dirt 2 is my only issue.
Does anyone have any ideas?
