I'm quite impressed by the new iTunes visualizers; they are very pretty by comparison to the previous ones (I particularly like the Jelly one). I'm running Leopard on a MacBook 1.83GHz with a gig of RAM. I'd like to up the frame rate a bit on the visualizers; I was wondering if getting more RAM help with that? Also, as I was looking in the activity monitor, I noticed that my VM size is apparently 39.56 GB (!!!!), which is very weird, because I have a 60GB hard drive. Is that something to be alarmed about?
