Since I put the new ati drivers ( for ati radeon 7000 Mac Ed) quartz extreme is not enabled, reffering to "quartz extreme check" I tried many times to put again PCI extreme but when I check I ha ve "this display is not enabled" Any solution? (Mac Os 10.2.3) |

The scores drop because if your processor is idle and you ask it to do graphics work it will kick the crap out of a radeon (my g4 does anyway) anyday. the processor has more power but will get bogged doen faster with out it enabled, when all you GUI and graphics work get taken off of the processor it is freed up for other things and your GUI does not take a hit when you start running processor intencive apps. I have found that games play better on my g4 with out QE but the GUI proformance is much better with QE. This is a problem if you like games... |

My experience with QE on my 8600/sonnet 800/ATI 7000 (in slot 3)/1GB RAM is that my critical work-at-home app (X11 from Apple) is sooooo much faster and more stable! I'm constantly popping from window to window and the QE makes a significant difference. Of course, much of the current slowness is from lag in the VPN line, but that's uncontrollable. I'm curious about saturating the PCI bus and want to try some tests with sampling audio while running QE. I don't do video work, but if the audio work that I do is effected by QE, then I'm going to turn it off. What's a good, repeatable test to saturate the PCI bus? It would be nice to have a guage/meter to see when this bus reaches saturation speed. I would suggest top, as top under my solaris box defines IO wait, but top on my mac doesn't. Stephen |

My experience with Quartz Extreme from 10.2-10.2.2 was that the UI was definitely sped up. I could put transparent terminal windows over the DVD player window and not see any dropped frames unless I was moving windows around. I could also put any window over the Quicktime player window and not see any artifacting. With 10.2.3 that has changed. I do now see performance hits when performing any of the above tests. CPU usage continues to be lower with QE enabled vs QE disabled. One confirmed problem with QE running on a PCI card that I experienced was performance problems when doing video capture. The qaulity of the video stream noticeably decreased and there were sound dropouts during the video playback. If I am doing any video intensive work I have to disable QE. Interestingly, in 10.2.3 I think that game performance is a little better with QE enabled. It makes sense that it would with the Graphics card taking over video processing full-time. But at the same time this observation is a counterintuitive. With all the data going over the PCI bus I would expect a drop in game performance. Nevertheless, Return to Castle Wolfenstein seems to run a little faster with QE enabled. Anyone have thoughts on this? For the most part I leave QE off under 10.2.3 because the latest rev of Mac OSX seems to have introduced a slight degredation in performance that I notice over what it was like in 10.2.2. I need to experiment more with the slot order of my Radeon card to see if that will make a difference. Right now it is in slot 6.

Nice acceleration through PCI Extreme... Quartz Extreme Check shows it works - the display is accelarated. But my SpeedRun graphics score dropped from 140 to 45. In X Bench my Quartz Graphics Score dropped from over 50 to 40 and the User Interface Score from 51 to 37. Running the restore program actually restored my old scores again, and the QE Check confirmed 'not accelerated. Has anyone actually experienced an acceleration through PCI Extreme? My system: 8600/200 with G4/800 and Radeon 7000. |

Thanks at all, especially mjoecups358: after re-install 10.2.3, I had to re-use PCI extreme to re-enable Q.E. I had noticed ,before, that 1024 pixels for "Tile Height and Width " makes screen snapier. It's always true... |

To clarify, The ATI october drivers are older then the 10.2.3 ATI drivers and don't in fact work at all. So you need to reinstall the ATI components which you foolishly (I did it too) over wrote... Reinstalling the 10.2.3 combined update is a simple way to do this. If you have another 10.2.3 install available you can also copy the following files from System/Library/Extensions/ ATIRadeon.kext ATIRadeonDVDDriver.bundle ATIRadeonGA.plugin ATIRadeonGLDriver.bundle Good Luck, Marty PS you would obviously have to do that as root... If you don't understand this then the combo update is the fix... |

there is an app that will extract just the part you need. I forget the name, and it may be easier to just reinstall |

You need to re-install the 10.2.3 combo update after the ATI update. After that you should have no problem. |

Try using PCI Exteme! to enable it. It is 1000 times easier than rumaging through the files to get it. |
