For all you ATi duders out there. Tried it out myself before lettin' ya get a crack at it. Install was kinda wonky but it worked and I seem to be doing alright. Pics for old/new version. It says 10.3 for both because ATi doesn't update Catalyst numbers for betas.

Your mileage may vary.

Apparently these also fix slow load times in BFBC2, but are slightly older then the ones in the previous post, but it's from AMD so the download is faster as well as smaller bcause you can pick and choose your OS.
