For those with crossfire, the dirt 2 fix is perfect. I didn't go the radeo pro route, I just renamed the exe to dirt2.exe.
I now get 45 to 95 fps. Before I got 35 - 55. (Both cards were @ 100% usage but the scaling wasn't there)
With ubersampling I get almost playable, but not. Like low 30s. It would probably drop lower in some areas, but I just did a quick comparison in the opening jail scene after I renamed the executable. uber on - 30's; uber off; 80+
And as far as the shadows, it's not nvidia thing, it's just the way the game was made. That crosshatch dithering(not that I even know if that's the correct terminology) doesn't look bad to me. It doesn't look good in stills, but during live gameplay it looks fine. image quality is great.
There'll probably be a mod for those of you that are really bothered by the shadows, but if ask me you're just obsessing.
