Thats GeForce 3 and NV20. The GeForce 3 introduction for apple, where Doom 3 was shown the first time. We who tested the alpha knows that D3 on GeForce 3 is not a good idea. Best Regards JemyM

Actually its fully possibly. They've stated that the FF Demo runs without one thing. RAY TRACE LIGHTING The ony thing holding them back. They use other methods to simulate Near ray Tracing effects but the demo DOES render FF Movie in real time. Just with slightly worse lighting
