HiI installed a sound card to relieve my mobo of having to process sound.I have got a few extra fps, but the ground textures stutter unbearably.I have disabled mb sound processing in the bios and downloaded the latest drivers for my Gainward Sound Card.When taking of from bumpy airfields, the sim freezes when the tyre screech sound tries to play.Also strangely, when in flight with the stutter occuring, I can hit the alt button to bring up the toolbar, and when I return to flight the stutter has gone until I switch views. So I am now confussed as to whether this is a soundcard issue or not?Any ideas would be appreciated.RegardsGraeme

maybe I'm clearing a scenery cache or something when pressing alt.What about sounds, do they pre-load?
