I recently bought a second 6770 to crossfire with my other, and while crossfire is running, I have some problems with skyrim. It's not so much of a performance problem though, it's just that when crossfire is enabled my characters face in 3rd person flashes (light and darkish versions) and when i press escape, (pause) It flashes yellow and then back to normal really fast. (I can make out what the main menu is and save/load etc.) I have all the latest drivers and nothing has helped. Does anyone know a fix for this?
