HI I'm using X 4.00 and Kde2.0 as the Windowmanager with my Geforce256 grafics card. I used the nv-driver from S.u.S.E 7.0 for X 4.0 at 1280*960 Everything works fine until I try Gl-Applications, like the "Tuxedo" game, which runs at maybe 1-2 fps. Before upgrading to X 4.0, it ran smooth. There are no errors reported by X so far, that could indicate that there's anything wrong. Thank you for your help, Till Sawala
