iTunes visualizer behavior
Very strange stuff.
I d/l iTunes onto my XP box at work (2.6 P4, 512) and turn on the visualizer. It gets in he low 20s for frames normally, but I notice the frame rate jumps 10 or 15 if I click on the iTunes volume and hold it. So after blinking in disbelief and clicking all over the window without similar results I try it a dozen more times on the volume slider just to be sure. Sure enough, frame rate jumps when I click and hold on the volume slider.
Anyway, I get home and try it on my stock 1.8 DP and it goes from mid-30s down to 9 as the whole thing gets choppy. Just the opposite of XP.
Ideas? Is it just Friday and a week's worth of work has toasted my brain?

Fair enough though, since a lot of Macintosh ports of Windows software are typically called "slapped together" by our masses.

This has to do with shoddy coding more than anything. I'm not shocked to hear about this issue; a lot of my friends that run Windows boxes claim iTunes is a pretty slapped together piece of Windows code.

It is slapped together, like they just threw their brushed metal and icons in a vb form and put in a few QT codecs and compiled, thus getting to the root cause of itunes slowness on windows, QT for windows, compared to WMP, BSplayer, real 8, mplayer classic, or any other windows player, QT is slow and bulky, they need a good team of windows engineers to streamline their windows code, there has got to be something screwy in QT on windows, it also takes a long time to respond to clicks
QT is currently built on top of the Mac Toolbox from OS 9 and earlier; QT for Windows essentially ports the toolbox to Windows, with all its lovely assumptions about cooperative multitasking. It's not pretty at all, and especially on Windows it's really inefficient.
One big reason why people are excited about QT 7 is that it's rumored to be a ground-up rewrite. Apple finally has the opportunity to remove the legacy of MacOS from QuickTime and turn it into something that runs efficiently on a modern architecture.
But until that happens, yeah, it's lacking on Windows.
iTunes on both PC and Mac seems to have another Visualizer bug starting back in 4.1. The fps never goes above 30. And YES I made sure the limiting button is unchecked. Tried all combinations. Was hoping an update here or there would fix it, but nope. 30 fps on a PowerBook G4 12" rev A and a fairly new Dell PC with XP. That's an annoying bug. Maybe they'll fix it in iTunes 5, and perhaps just update the visualizer as a whole? G-Force has eclipsed it quite thoroughly.

Don't know if this is the cause, but this can happen if vsync is turned on and there is no triplebuffering. Refresh rate of 60hz * 1/2 = 30fps, * 1/3 = 20fps, etc.

two truer statements were never uttered!
