Poor performance in the demo.

Try turning of Aero in Vista before running the game and see if that helps. During the whole development of the game I have used a GeForce 6800 GT on a 2.0 Ghz Athlon with only 1 GB RAM and have had the level editor, model editor running at the same time as playing the game. So it really should be behaving quite nice on your computer unless there is some specific conflict making it slow down.
