useless driver... good fps though, but still many problems with crossfire (got 2xhd5830). I use 10.10e which gives me best quality with still decent fps (BC2 45-110fps (I use VS) MSAAx4, AFx16, maxed out, 1680x1050). the 10.12 and 11.11 is 5 fps + at leat but it makes my cards do weird things to textures (flickering textures, black intermittend screens). I wish they use 10.10e as a base for 11.0 or they will come up with something completely new, which I doubt. The new interface is more windows7-like and as useless as the driver. I hope they will give me a fix for source engine games. i can't play them in crossfire mode/AFR.
