its is just very very bad coded just look at the performance of nV vs ATI LOL even ATI fanboys have to admit that 2x-3x the performance of the-same-level-nV-card is total BS and LOL you need a new driver for this game to display it correct ?!?! where is the ultra hyper cool extreme feature that needs that ?

Why does it not run on GF4 but runs on 8500??? You answered your own question, the 8500 fully supports 1.4 and it's pixel shader unit is significantly faster than the GF4's.
