    YES! A little extra glory for my old G4 400 PCI graphics with a Radeon 7000! By default, Quartz Extreme is NOT enabled for any computers with PCI graphics. HOWEVER, check out the following forum for a discussion on how to override this!

    While the results weren't staggering, enabling QE actually did boost performance! Keep in mind that this will only work for PCI RADEONS. It will not work for original Rage cards.

    This is a beautiful thing. :cool:

    Update

    Update: A utility has been released that will automatically change the config file without having to root through the system:

    http://www.versiontracker.com/moreinfo.fcgi?id=16006&db=macosx

    " PCI Extreme! enables machines with PCI graphics and a compatible graphics card [i.e. PCI Radeon/Radeon 7000] to use hardware acceleration in Quartz Extreme, the new composting engine in Mac OS 10.2, Jaguar. Hardware acceleration for Quartz Extreme on PCI machines has proven to boost performance by 5-15% when performing light tasks such as web browsing, e-mail, and word processing. However, it slows down heavy tasks such as encoding or decoding video, especially DVDs by up to 50%. This results in dropped frames, studdering audio, and video falling out of sync with audio.
    Bottom line: When the GUI is piped through the slower PCI bus it tends to choke up other tasks that require heavy processing. "

    So it's not ALL good. Maybe Apple disabled it for a reason after all... :rolleyes: :D

    Strange, I did a search for "PCI Radeon Quartz Extreme" and the engine didn't come up with any matching results related to the subject... sorry Spark. You get full credit. :)

    Hey G5orburst, would you be so kind to tell us how, or post a link I have a rage with 8 Mb myself, and you know that I want to enable it if it speeds up things.

    YIKES! (No pun intended)...

    Well, I'm back from testing my G4 with and without Quartz Extreme. And I must say I'm pretty surprised.

    I used the program SpeedRun to test the results of my computer before and after. Here are the results. Computer was freshly booted and run in identical settings (i.e. programs and windows) in both cases. All numbers are an average of SEVEN test results. LARGER numbers are FASTER/BETTER:

    WITHOUT QUARTZ EXTREME:
    Graphics: 256
    Hard Drive: 322
    Processor: 147
    RAM: 261

    WITH QUARTZ EXTREME:
    Graphics: 108 :eek:
    Hard Drive: 315
    Processor: 147
    RAM: 261

    HOLY SMEG! The graphics performance FELL about 150% with Quartz Extreme enabled! My computer is a G4 400 PCI with 1GB RAM and a Radeon 7000.

    Bottom Line: Almost all G3 users have reported slight to significant improvements with enabling Quartz Extreme on their computers. Me, however, I think I'll go back to the way it was... :p I definitely wouldn't recommend this for Yikes G4 owners with my configuration.

    i have no idea i how he did it. he said it ran pretty poorly, but it still ran. It wasnt something anyone else figured out, he just did it. I'll have to ask him how he did it.
