Hmmmm... Shocking, I know. I have tried everything and the only way I can get the DEMO to run ok is to turn off the CPU-based hardware T&L (otherwise known as Geometry assist) and jack up the z-buffer to 24 bit and all other color settings to 32 bit. With Hardware T&L I can hear it, but I can't see it. It closes the program completely when I try to benchmark. Not good!!!! I won't be getting my new Geforce 2 Pro for a week yet!!! Help me run this!
