A couple of months ago I was struggling with low fps, especially in races. I was down to 16 fps at the beginning of a race (my FPs were set to 33). I overcame this to alarge extent by optimising certain Bios settings. I wa getting 21-22 fps on the grid.
However I recently uninstalled my cat drivers and replaced them with 26.40 Omegas (hacked version). WoW! :-0. On the grid my FPS (now at 37 fps) stayed right there. At the back of the grid, same thing. I turned on the rain at Silverstone. Back of the grid dropped slighty 35-36 fps but stabilised to 37 again once we got moving.
Replay of the race in the rain? a steady 37 fps. I'll stick with these omegas. Blooming marvellous. Oh and i'm driving at 1280x1024 everything on including haze but mipmapping on static. This game is beautiful. So you Radeon owners go try out these drivers.
