Which OS X version do you have? If you upgrade to 10.2.3 (if you don't have it), it's a LOT faster than previous versions, especially on older Macs. Also, which Sonnet card do you have? I have a G3/400/512 in my 9500, and scrolling and the genie effect are quite fast in X (I have an ATI Rage128 PCI, similar in speed to the Radeon 7000). >The ATI card I have is the PCI 7000 Raedon .. from what I could gather, >only the AGP cards can take advantage of Quartz Extreme's >compositing/decompositing >offloading to the video hardware. With a PCI Radeon or GeForce card, it is "possible" to enable QE with the above noted hack, but it will generally make your computer slower overall. PCI doesn't provide the bandwidth necessary to use QE. Also, when using QE, the bus is pretty much dedicated to video, so if you use it on PCI, you end up slowing down other PCI cards, like USB, IDE, or anything else you have added. This isn't a problem with AGP, because AGP only supports 1 device on its bus. Remember, even if you don't have QE, you still have Quartz, which is a very similar technology, the only difference is where the rendering takes place. BTW, window resizing in X is always slow (even on a brand new G4 PowerMac). That's just the way it is, and until they rewrite that section of the code, it will remain slow no matter what video card/processor combo you have.
