Well, I just sent in my 5770 for RMA (cooling issues) and decided to take a GTX460 as a replacement while I wait for the ATi to get sorted. One thing I was quite surprised about was just how horrible my performance was - I had 19FPS in Innsbruck, where with the 5770 I had 25+ easily. Since a lot of other people say they're getting quite good performance with their nVidias, could I be doing something wrong? XPlane was installed while I had an ATi, could there be some setting that was applied that hits nVidia cards hard?
