My refurb eMac 800mhz that I purchased a week ago came with Jaguar installed. I was playing around with it (since i've never used Jaguar before), and I was quite surprised with how fast the visualizer ran compared to my old iMac 350mhz - about 40fps with the default size window on HQ. Later that day I formatted the HD and installed Panther off the CD's it came with. When I tried out iTunes, the visualizer was only giving me 20fps with the same size window! Even after I overclocked to 1.4ghz - almost double the speed, the visualizer still only barely hits 30fps. I know i'm being picky over something so frivolous, but i'm wondering why this is, or if anyone else has noticed this.
