For the V3, in the driver settings set the 3d filter to on, and alpha blending to smoother. It will make the color look better.
But the V3 chip was basically a combination of the Voodoo Banshee and Voodoo2, so 32bit was not an option. 32bit 3d rendering on Voodoo cards is only possible on Voodoo4 and Voodoo5.
