Well when i wanted to see if i could use my old diamond 3d II with creative geforce2 i run into some problems. The install went fine, however when i tried to adjust any settings for voodoo2 in display properties, it would freeze completely. Windows itself would work fine. Also powerstrip didn't see voodoo2 at all. In q3 when i selected glide driver, it would still use geforce2 and not voodoo. That's about all i tried to do. After i took my voodoo out and never tried to use it again. Maybe there is a way of using them together, i don't know.
