I'm simply pointing out that today, 3d tends to be specialized in two directions: games and work. games want big, fast texture maps with low to mediocre resolution, but high frame-rate. work (here I mean scientific visualization and probably cad/cam) wants big resolution first and foremost, and quite possibly no texture mapping at all. 3dfx voodoo cards, for instance, do wonderful 3d games. I have a hard time imagining anyone getting actual work done on them, though, since they're quite limited in resolution. my impression (NOT based on experience!) is that Permedia chips are indeed derived from the 'work' world, and don't pander so much to the "framerate in quake" crowd. personally, I'd rather have a dumb framebuffer and decent interconnect, than a "video coprocessor"... regards, mark hahn.
