odd that i'm getting 5-15FPS better with WoW now than i was before.
seems that Leopard is pretty much even overall though. i mean there isn't much difference in any of those FPS at all. and Aperture is obviously running better. could just be a driver issue too.
What mac are you using? Improvments with Leopard for WoW can easily be contibruted to running on G5 or G4 macs due to OpenGL drivers being enabled for multithreading and some other driver improvements. Intel macs should be very similar performance.
