That's great but doom doesn't use polygons and is a texture mapped raycasting engine. Super FX does help speed up some vector math operations but it's still quite limited. If you played SNES doom you would know it's really pushing the system to the absolute limits. The frame rate is pretty low and cropped play area is small. They had to simplify a bit of level geometry to get the BSPs and other level traversal logic for stuff like enemy AI to fit in memory (which was 128 kilobytes!). They didn't even have enough CPU power to texture the floor and ceiling.
