After installing that latest version of catalyst control centre (12.8) I can't see or use any of the AMD pre-defined crossfire profiles. While using 12.6 everything worked great, and my two 6850's took everything I threw at them, now they're running like they have a disease. I've tried wiping all traces of ATI software from my computer using driver cleaning programs, I deleted the windows installer information, I've tried re-installing over and over again but everything still runs like I'm trying to play a modern game on an N64. When I turn crossfire off, everything runs better, but not nearly as well as they did with crossfire in 12.6. All my hardware checks out for crossfire so they're not an issue. In the 3d settings tab for catalyst, the drop down box for crossfire modes shows an empty list when trying to choose a pre-defined profile. Every time there are new ATI drivers I feel a knot in my gut because I know I'm looking forward to a week of troubleshooting, but this is the first time I haven't been able to find a solution. Any ideas?
