OK, Stephen, I modified one of kano's scripts to use the src files (4363) and url (download.nvidia.com/...) you gave me and still get the same glxgears result.

Could it be that the knoppix install is more efficient than the debian install? No matter which nvidia driver I use, I only get 300 fps now. How is it that I had gotten 600 fps before? How accurate is glxgears?

Is it good enough to have glxinfo read true for DRI and that glxgears returns a higher fps with the drivers than without?

Thanx,
