I see a new WickedGL has been released also. Give it a shot.
The Wicked3D WickedGL downloads page has a new version 2.30 of the WickedGL alternative driver for owners of 3dfx Voodoo-based accelerators. The new version adds support for TreadMarks, Hitman, BGII, Parsec, Crime Cities, and Snok, fixes texture compression in SoF, HW lighting in SoF and MDK2, a "white screen border" bug, and a bug with low detail mipmap loading in Serious Sam and Q3A, and adds a compressed textures cache so that Quake III Arena loading times "have been cut more than in half."
