On XP64 Catalyst 7.11 everything OK
On Vista x64, Catalyst 8.2 great improvement. I had many stutters and land textures corrupts in game. Now it is OK.

I am using Catalyst defaults with AA 2 AF 4 on XP.
On Vista I have the same but also I must enable Vertical synchronization and tripple buffering to eliminate remaining little stutters.

I am using OpenGL and perfect mode.

You might want to try 7.11 in vista as well, I have an X1950Xt and frames are almost cut in half with any of the 8.x drivers.

On XP the situation is different. The last good working ATI driver is 7.11. In all 8.X I have about 1/3 lower FPS. Really I cannot understand this dramatic decreasing.

It is interesting that when I compare performance vista drivers to XP 8.X drivers I am obtaining identical results.
