Ok. So I just bought another gigabyte amd radeon hd 6670 1gb card. It hyper crossfires BUT, skyrim lags like hell when I put both together. But if I run just one, it works like a charm. I've tried renaming it to Fallout3.exe, tried 11.11, 11.11b and 11.11c but none of them work either. I've even tried the alt+tab trick but that doesn't work. PLEASE HELP!

Just to be sure...Have you downloaded the application profiles?

Also, you should be using 12.1 drivers.

thanks a lot. My rig is 2x AMD Radeon hd 6670 1gb, core 2 quad 2.4 ghz 8gb ddr3 ram x48c platinum edition msi motherboard. I'll try out the 12.1a and see if that works. Cheers! :/

Umm... It made it REALLY bright, light flickering all of the time and still just as laggy. Any more suggestions?
