Crossfire used to work on Battlefield 3, but after updating drivers, no longer works at all. As if the second GPU isn't even recognized. Crossfire works in other games though. Performance on 1 6950 ranges from 40 to 60, and i used to get 70-80ish depending on the map, sometimes more. Any suggestions?I've tried multiple drivers and am currently on the official 12.7 beta.
