PDF Slide Show Explains Jaguar’s Quartz Extreme

Good information at MacNN: “A PDF slideshow used at Siggraph 2002, written by Peter Graffagnino of Apple, provides information on Quartz Extreme. It will be available with Jaguar (10.2) on August 24th, and is the first OpenGL-based windowing system. It will feature true system integration (Quartz2D on a texture, Video on a texture), improved texture upload performance, programmable shaders, many new extensions, and new tools.“. Read more to check out if your Mac can support Quartz Extreme.The Quartz Extreme functionality is only supported by the following video GPUs: nVidia GeForce 2MX/3/4MX/4Ti or any ATi Radeon and ATi Radeon Mobility GPU.


A minimum of 16MB VRAM is required for lower resolutions (up to 1024×768), more VRAM you will need for higher resolutions. The more graphics memory the better, especially if you have many windows open at the same time, even if they are minimized.


Due to the needs of this kind of technology, the board needs to be at least an AGP 2x (AGP 4x recommended). PCI can not be supported because of its bandwidth constrains: PCI only does 133MB/s while the minimum needed by the technology, AGP 2x, does 533MB/s and AGP 4x does 1066MB/s.


The ATi RagePRO/128/Ultra as found in the older G4s/Cubes/Classic-iMacs, any iBooks purchased before 2 months ago or any other Mac that do not match exactly the above configurations, will not be supported by Quartz Extreme.


Especially if you own a G4, MacOSX 10.2 Jaguar has optimizations that will make your desktop almost twice as responsive when compared to OSX 10.1.5, even if you do not have a Quartz Extreme capable graphics board. With QE enabled, performance goes up to three times faster than the current 2D-only desktops (provided that the resolution is not ultra high and not a zillion of windows are open or even minimized).
