AGEIA PhysX card demo pictured
 

The demo had hundreds of barrels, boxes and other pieces that you could shoot with a great cannon and create some great physics experiences. We saw the demo of the PPU card with two Nvidia's cards in SLI versus the same machine with same SLI cards without Physics card. The guys ran the demo on both machines simultaneously and the machine without Physics Processing Unit was rendering only a few frames per second. The one with Physics card inside was rendering the same scene at more than 30 FPS constantly. It's 6 FPS without versus 30 with, not bad at all. It just looks great and we even have a picture that might show you a little bit what it's like.
