Quartz in older G4?
I was under the impression that I would not be able to take advantage of Quartz rendering on my G4/400 (AGP) with OEM Rage Pro card. Yet when I install Silk and enable it I seem to be getting all the benefits of text anti-aliasing in cocoa apps such as IE. etc. Whats the status of Quartz rendering on this older G4?

You are confusing, I think, Quartz, and Quartz Extreme.
Quartz is the term for the entirety of the dipslay layer in OS X. It is what handles ALL of the graphics that you see. However, Quartz Extreme is an advertised feature of X.2, announced but not released. It purports to hand of much of the display processing to the graphics card, rather than as it is now, handled by the processor. As such, it requires a very fast connection to the graphics card, and a very fast card. As announced, it required a card with 32M VRAM. However, that's been now modified to "recommended for optimal performance". So--you do, in fact, benefit from Quartz. How much you benefit from the added performace of Quartz Extreme remains to be seen, but I think you'll find it pretty good on the system you describe.

If you have a G4/400 AGP you DO NOT have a Rage Pro. I have a G4/400 PCI and I have a RAGE 128 in it. So, you probably have an ATI Rage 128 AGP card in yours if not something newer. The Rage Pro shipped with the B&W G3 machines and earlier iMacs.

I've got a Rage 128 in my B&W G3 400. Rage Pros are in iMacs, probably early revs of the B&W G3, and PowerBooks. I could be wrong. |
