Full Screen, default settings (could not find high/low quality setting!)
15-28 (avg 22)
Medium window, Explorer open in background
No music while moving window around
Music playing while moving window around
These numbers are exactly why I'm still unimpressed with OS X's speed. iTune's basically a screen saver for crying out loud and it's nowhere near as smooth as, say, Unreal Tournament, which has a lot more going on.
Also, so much for multitasking, notice the fps drops when moving the window and with apps open in the background.
iTunes performance=lame. Even on the DP machines, the fps sucks. Sheesh.
Now watch, I'll get blasted for daring to criticize the mighty OS X. IMHO, none of us should settle for this kind of performance in today's machines. If I had dropped $2500 for a DP machine and its own built-in screen saver/music player couldn't even hold steady at 30 fps no matter what on a multi-tasking, multi-threaded OS, I'd be pissed. I'll forgive my iMac, cuz I never expected great performance from it.
