To be sure what demo, demo four or demo001 or which one did you use?

The person Kas1e, only claims 40 or so fps on demo four? I will just have to make some videos and upload them. Both my MDD G4 and G5 GHz did basically the same on a Radeon 9600. 41 FPS on the 1.5GHz MDD, and 44 on the G5 2 GHz on 1600x1200.
