Thanks for the great list. I have an MSI nVIDIA Ti4200 8X 128MB video card that is extremely jumpy with Tux Racer and 3D screen savers. Will drivers from the nVIDIA site help this or do I need openGL drivers (which I couldn't locate for this card)? I am asking this question instead of experimenting because I am paranoid of losing my display and not having the experience to bring it back. Thanks. Bradley
