Under OS X, OpenGL hardware acceleration is fully supported on any machine with a Rage 128 or better (that's Pismo or later for laptops, and Blue&White G3 or later for desktops). If you have an AGP card with 16MB or more VRAM, parts of the GUI will be drawn using OpenGL.
All the iTunes "Use OpenGL" button does is use OpenGL to speed up some of the 2D drawing operations. If you've got 16MB or more VRAM, the difference should be noticeable.

Is OpenGL user configurable? Or is this one of those background things? And is there a certain (gulp) video ram requirement just to make it work? Or is it always "working"? I was enjoying the Visualizer in iTunes today and noticed that under the "options" button, I had clicked "Use OpenGL". . . which spawned this thread. Have a great day everyone!
