Tim, a further clarification... Internal calcs are done at 32 bit and then dithered to an "effective" 22 bit which is essentially a proprietary method for rendering higher quality using only 16 bpp. <<With each pass, precision is lost...>> Yes, but Jeff is right. At higher resolutions those minor errors should be less noticable. Visual gameplay is a mix of color/framerate/texturing/resolution. As the Riva128 showed, there are methods for giving up visual quality for performance. Voodoo3 will have extra power to burn so we may be surprised at what cool things we can do to enhance visual quality. For example, Everquest is limited in resolution but Voodoo3's fullscene AA will improve the visual quality beyond what 32 bit only could do. Other video cards will be unable to have to power to implement such a visual enhancement without slowing this down to a slideshow. Pat P.S. What if those Nintendo emulator ports got licensed and marketed to the PC industry. 3dfx would be the only graphics chip to be Nintendo compatible. Now THERE'S your new market Jeff. Why don't you call Ballard and see if he'll stike a deal between these developers and Nintendo?

Nope... the voodoo does things at 32+ bits internally. it also maintains 32 bit precision when multi-texturing. Artifcats are only introduced if multi-texturing is done manually (ie: DX5), or when more than 2 textures are used per triangle (ie: Unreal). Truth be told, the loss in performance for games that require 32 bit precision (ie: 4+ textures per pixel) would also suffer the most performance loss.
