Hmm, tech from '95... using VESA BIOS extension and high/extended memory modes, you might be able to modify Doom source code for the optimized 3D operations, but you'd still need to create a LODed-megatexture database and an API to serve it, unless you want users to "Insert CD 23 and press Enter".

Haha, just do a planet sized doom level. Easy peasy.

Good luck trying to do any sort of 3D rendering in Doom ;)
