Speed up iTunes 4 visuals on older Macs
Authored by: twalther on Oct 16, '03 03:35:47AM

Even more interestingly, this option has different effects depending on use in Fullscreen/Window mode. My machine is a Dual-2.0 G5 with Radeon9800 and a 20 inch Cinema Display, and here is my experience:

--With OpenGL enabled on the visualizer, the visualizer seems to max-out around 65 fps in either fullscreen or windowed mode (performance is nearly constant full-screen, while may vary in window)

--With OpenGL DISABLED, fullscreen visuals SLOW DOWN--to around 35-40 fps. I suspect this is due to the large screen area.

--With OpenGL DISABLED, and using a moderate-sized (likely fullscreen to many) iTunes window, framerate INCREASES in window mode, to 85-90 fps.

Why is this? I am not sure--but I suspect it has something to do with the fact that the CPU doesn't like driving that many pixels on its own in fullscreen mode.
