Beautifully fluid for me but two points
1) From the latest download - all those files in the \shader directory must go into a \shader directory beneath the main directory of the demo - putting them in the root directory itself gives you all those errors noted above
2) Changing AGP APerature size up to 256MB or 512MB given you have sufficient memory really makes the demo fluid. On my 9800 Pro I'd say at 1024 * 768 I am getting at least 30 fps
