YoYo, I had the same problem on my G4/466. Diablo II would slow down to about 2 fps or stop altogether. Giantmike suggested trashing the ATI drivers that install with 9.2.1 and downloading the latest Radeon drivers from ATI's site. They work with the Rage 128 cards too, of course I don't know what VC you have, but give that a try.
