After messing around with RivaTuner, it appears that anisotropic filtering may be working in FU3 after all. I decided to switch off the aniso in RivaTuner, and then check to see if this had made a difference in FU3. I discovered that aniso does indeed reduce the amount of texture shimmering, although I am still not convinced that it makes distant textures look any sharper. In fact, I know it doesn't.So, it seems that a combination of anisotropic filtering and 4xS anti-aliasing produces the best visuals on my GeForce 3 Ti 200 powered system.Chris Low,ENGLAND.

Yep, I agree that the few blurries around the horizon in FU3 apparently can't be eliminated completely with an Nvidia, even with max AA and max Aniso on a GF4 Ti4600. But then, DX9 is now available in beta, maybe it will help. I'll wait for the official release though. Or a new driver might do it...
