The fact that it runs it is already a feat. But then again, it's hilarious seeing how far OpenGL has evolved, especially with the Glide chipsets.
I love the fact now you can cheat in new games that employ strong lighting technologies, by simply using these kinds of cards to remove all sort of lighting, haha! It must have been quite a "scary" adventure on that card too.
I wonder what Carmack has to say about that though. Seeing his GFX engine looking like that, he would probably faint.
I dunno about the polygon being THAT in reality, I think DOOM III used much more. It's true Carmack didn't use a lot of polygons per model, but over 4000 was the norm IIRC, and it is far from that which the Voodoo 2 showed. It wouldn't surprise me if some shader technologies like vertex manipulation weren't used. The overall look is far from smooth. Lighting could do so little to save these moving shooting boxes!
