ah.... the benefits of protected memory. Although I have had Bryce puke out and crash on me once or twice on win 2000 on my laptop. It's pretty interesting: I've got a G4/400 Mac at home, and a P3/500 laptop at work (that I carry with me on a train commute). I can do head-to-head comparisons between the two systems.... and they're pretty well identical for render speed. I rendered the same scene on both machines: the times were 16:54 for the G4/400, and 16:08 for the PIII/500... go figure! One of my co-workers got a new system (at work) with a 1.3 GHz processor... I'm eager to sneak in some time and see how fast Bryce runs on it :-)
