I have a 3D Blaster 2 from Creative. Their last driver is from early 1999, compared to 3dfx's reference driver from 2000, so there is no DX7 support.
Creative's driver on the other hand allows overclocking from the control panel, which is very nifty.
I can't decide which driver to use, so I need some opinions.

You could try to mix the two drivers.
