I backed up to the 4496 drivers and went from 75.000 fps to 645.000 fps. Not sure if that is the best I could expect but at least Tux Racer seems to run normally. It is too bad that NVIDIA seems to have neglected support for the older TNT2 cards. I am sure I am not the only person that still are using this card and have no desire to upgrade. I had always been very happy with the TNT2 card but if NVIDA is going to do quit supporting this card what is saying that they are not going to quit supporting a new NVIDIA card that I might buy to replace in a few years. Defiantly going to make me think twice about buying a NVIDIA card in the future.
