Simple enough, I have an iBook G4 at 1.33ghz, 1.5 gigs of RAM and the default 32 megabyte gfx card. So Quartz Extreme is supported and Core Image is Hardware Accelerated. My question is this: Is there anyway to smooth out the graphical effects? Even the simple ones that have been in EVERY release of OS X (like minimizing and sheet dialogs) are choppy and skip frames. They run perfectly in OS X Tiger and they haven't changed at all so they should work fine right? On Better Performance, while plugged in, on a good day, they run fairly smooth but they don't normally. I've gone through the system processes and nothing's bogging the system. This is also a fairly fresh install of Leopard so it hasn't built up any kind of clutter yet. I also have an idea.. would the older version of Quartz Extreme in OS X Tiger work better in Leopard? Like, downgrade Leopard's version down to Tiger?
