Quartz 2D Acceleration in the future?

I just stumbled upon the following in the updated Mac OS X SystemOverview.pdf document:

[quote]

2D graphics

acceleration

Supports two-dimensional graphics acceleration, improving

what is currently available in QuickDraw. (Acceleration is

currently limited to system software and Classic applications;

other applications must draw into backing store in DRAM.)

[/quartz]



If this ever happens then Apple would finally have closed the last performance gap that still separates OS X from OS 9: 2D graphics acceleration.

Before you ask, Quartz Extreme does not do that: it only accelerates compositing once each window has been drawn by its respective owning application.

    It's called Quartz Extreme.



    Yeah, it's only for the compositing, but the text you quoted was rather vague on that part. I think it's still referring to QE.

    <a href="http://www.macsonly.com"; target="_blank">Macsonly</a> has today an analysis on their experience with 2d acceleration and QE in MacOS X. Very interesting!
