Re-enable Quartz Extreme on PCI-based 10.3.7 Macs
Authored by: larkost on Dec 22, '04 10:11:02AM

There is a reason that QuartzExtreme is AGP only... PCI is not fast enough to really do this, and it completely lacks the shared memory features that QuartzExtreme requires when dealing with large amounts of textures. Playing with it in this manner is asking for asking for problems and crashes.

Re-enable Quartz Extreme on PCI-based 10.3.7 Macs

For some reason, any forum talking about this particular hack becomes full of people saying why and how it can't work properly. Well, maybe it doesn't work for some people, but it happens to work perfectly for me and for many of my clients. I've been installing Radeon PCI cards for ages in Blue & Whites and using PCI Extreme on them with zero complaints. I personally use it to add Quartz Extreme on two secondary monitors in my Dual Processor G4. These monitors each run on their own Radeon 7000 PCI card. I also have ZERO problems. Without QE on PCI enabled, Expose is literally useless for me. With QE on PCI Expose is fantastic. I run an additional 2 monitors on my Radeon 9800 AGP (dual head), and for a while ran yet another two monitors on the PCI cards (which are also dual head) for a total of 6 monitors, and it handled it perfectly.

I don't have any of the quicktime performance issues some people seem to have on their PCI cards when running this hack. Might those issues might be limited to the old beige models with slower bus speeds?

Glad it works for you. Unfortunately using 10.3.6's CoreGraphics.framework on a 10.3.7 system is more likely going to cause bigger issues than whether QE is suitable for PCI devices or not.

There really is no performance benefit for enabling Quartz Extreme on PCI devices, so why would you want to enable this and risk not getting any future updates from CoreGraphics. This also means you do not get any bug fixes in CoreGraphics from 10.3.7.

There are performance reasons to use Quartz Extreme though.

it does reduce CPU load, and can make the GUI feel faster.
now on some machines I have seen the bugs that can happen, and didn't have time to diagnose why they occured on those specific machines, but on others it has worked fine, and is a nice boost in speed.
