8-tap anisotropic filtering was one of the features on the original list of specifications but was dropped by 3Dfx. Not that anistropic filtering is all that important- it's main use is for depicting strands of hair, for example. It's a method that looks great but in practice hits the performance way too hard (something that 3Dfx is philosophically against, rather adamantly so). Another feature that was taken off the original spec sheet is full scene polygonal anti-aliasing. As great as it looks (in terms of smoothing out those jaggy edges), 3Dfx felt the performance hit was, again, too great. Other than that, the 3D core is very capable, much the same as the Voodoo Banshee in terms of the image you get. Of course with its dual TMU architecture, the Voodoo3s images fly at similar speeds to a Voodoo2 SLI rig.
