IL2 and ATI 4870

Hi all.
I upgraded from an Ati 1950pro 512 to an HD 4870 and this card is great. Is a little bit hot but with new AtiTryTool the problem can be solved easaly. The FPS are always very good with the exception of a low fly over Berlin, now i'm testing and seems the new map of 4.09 runs better then older map. The driver are not optimised and probably need to wait next release. To ICDP: where i can disable Texture Compression?

This is my settings
