You could still get very good performance with VPC3 -- I keep it around to play older Windows games. Believe it or not, on my MDD G4 this is enough to run Shogo MAD in Windows 98 with software rendering at a frame rate that isn't atrocious. (I don't need it as much now thanks to my wonderful OrangePC 620 and the 400MHz K6-III I put on it, and I have the Mac native Shogo anyway, but at the time it was great stuff.)

VPC4 ruined that and the rest of the releases sucked for games.
