10.3: Exposť and Quartz Extreme on ATI Radeon cards System
For what it is worth, my Exposť performance was terrible at first, which I attributed to running a number (4) of extra displays on two Radeon 7000 PCI cards, in addition to my primary video on the AGP bus. Since Quartz Extreme isn't supported on these screens, Exposť was very slow, nothing like the smooth experience we've seen in demos.

I went ahead and threw caution to the wind and reinstalled PCI Extreme, which successfully enable QE on PCI cards in Jaguar, and was pleasantly surprised to find that it appears to function perfectly under Panther. Exposť performance is vastly improved, as are many other functions. Note that some users find that enabling QE on PCI cards can cause other performance issues, though I've never personally had this problem myself

10.3: Exposť and Quartz Extreme on ATI Radeon cards
Authored by: JimHarper on Oct 30, '03 09:15:19AM

Though I was able to successfully install PCI extreme and get Quartz Extreme acceleration on my Mac (Sawtooth G4 upgraded with a dual 500 Sonnet upgrade card), I did notice an immediate side effect. I have the dock set to auto hide. Without Quartz Extreme running, it appeared smoothly when I rolled over the side of the screen (I have the dock positioned on the left). With Quartz Extreme enabled, the dock emerges in choppy manner.

Since I don't like ANY side effects if I'm going to enable an unsupported feature, I decided immediately to restore Panther to non-acceleration for PCI cards. The way I figure it, if there is one side effect, there may be more, and though the extra GUI boost was nice (especially in Expose), I can't justify using it.

FWIW, Jim, the Dock choppiness is the *only* bad behavior I've ever seen under Panther, and under Jaguar, the only other issue was Quicktime Previews could become garbled when moved to a PCI-based QE screen. Not really a big deal. Others complained of DVD display issues, but I never had any. I really think you're missing out by not using QE on PCI screens (I use 6-8 screens, myself), unless you rarely use QE-based effects.

I just tried it on my Blue and White G3 450 / 512MB with a Raedeon 7500 PCI, man what a difference... It really makes the UI very useable, I was considering getting a G4 off Ebay or something, Panther runs a lot better than previous versions but was bummed to learn natively it didn't turn on Quartz if you have a PCI card. Thanks to this utility, that is not the case anymore!

i have a g3 b&w their u haven't any problems execept of the choppy dock. imo this is bc the g3 b&w have a 66mhz/32bit pci bus for the grpchic card with seperated controler, so u have a bus twice a fast as a normal 33mhz/32bit pci bus, althout a 2xagp slot ist again twice as fast.
