Alright, ive found a few issues and i'm going to put the solutions in here as they become available. At the time of writing this post, all these issues still exist on catalyst 9.4. Global issues: 1080P screens running in 1080i (30Hz) Mode in DIRECTX 10 GAMES (Some DX9 games have this issue, such as killing floor) Crossfire only issues: S3 sleep state causing graphics corruption after wakeup SEE EXAMPLE Second GPU running in 3D clocks when PC boots up, not 2D Some users (mostly dual GPU cards) installing any driver after 8.10 causes a code 43 upon boot in Vista (possibly Win 7 too?) causing 1 gpu, in a 2 gpu setup, to be disabled by Windows because of a incompatible display driver. Lets keep this thread clean and focused on problems and their solutions. I dont want this going off topic and people being unable to get help, because someones ranting about an un-related problem.
