10.4: Enable Quartz 2D Extreme on unsupported Macs
Authored by: petersconsult on May 15, '05 05:42:48AM

My 2 cents:

The FW800 Al PowerBook is actually Quartz2D Extreme capable, but that option is disabled by default.
Also unrelated, the 9600Mobility chipset on that PowerBook is seriously underclocked.

I have just set Quartz2D Extreme to be on (in the /Library/Preferences/ file only), and overclocked both the processor and memory using the ATIccelerator SystemPreference, and I must say that it really rocks!

As noted in xlr8yourmac, overclocking the 9600Mobility does not improve bechmarks in XBench, *except* with Q2d Extreme enabled: the 'text' portion of the 'Quartz Graphics Test' jumped from the usual ~220 to a whopping ~416!!

I have been using my PowerBook's 9600Mobility overclocked for a week now, and it is perfectly stable, even when playing X-Plane for hours on end.

I hope this helps...
