Real-time rendering of Doug Jones' head by NVIDIA - rendered on the new GeForce 8800 Ultra graphics card.
You read that right - REAL TIME. There may be just a little bit too much specular on the model, but even so, that's one impressive demo. Another couple of orders of magnitude improvement in GPUs, and we should be able to do a whole virtual world this well.
Another very pretty Crysis video. Holy crap, is the CryEngine 2 ever ungodly. If the game is anywhere near as good as the engine, this should be the best FPS ever made.
