thanks very much for trying to help but i'm afraid that makes no difference. the only way at the moment that i can get IL2 running silky smooth is by setting terrain detail (or whatever its called) to "very high" instead of "perfect" (that way all the trees and realistic water dissapears ) i definatelly had IL2 running smoothly on my system before with full graphics settings!! maybe i should install a different nvidia driver? i have 9800GT
