	Quartz Compositor - Wikipedia, the free encyclopedia
		Quartz Compositor is the windowing system that is responsible for the user interface in Mac OS X.
		To use Quartz Extreme, the Macintosh must have an AGP graphics card with support for arbitrary texture dimensions and a minimum of 16 MB of VRAM.
		With Mac OS X v10.4 Apple introduced Quartz Extreme 2D, and with it speeded up the actual drawing operations as well, so that as much of the compositing and drawing was taken over by the graphics card as possible.

		Quartz supersedes Quickdraw which was used in earlier versions of the Mac OS, known as "Classic".
		Quartz is based on version 1.4 of the Adobe PortableDocument Format (PDF — a universal file format that preserves all of the fonts, formatting, colors and graphics of anysource document, regardless of the platform used to create it.

		Quartz 2D running in software using the CPU has to write to the backing store in RAM, then that backing store has to be moved to the video card where the Quartz Compositor can put it into the final scene.
		Quartz 2D Extreme running on the GPU writes those 640,000 pixels into the backing store in VRAM, which is exactly where the Quartz Compositor needs to read it from.
		Quartz 2D was notoriously slow at drawing lines in Panther and earlier versions of Mac OS X, so much so that developers often chose to use (or in most cases, "stick with") QuickDraw for such tasks.

	IGM: OS X Journal: Closer look at Jaguar's Quartz Extreme
		Quartz Extreme will allow Mac OS X to offload most of these Quartz graphics to the graphics card, freeing up a significant portion of the CPU to work on other tasks.
		Quartz Extreme is progress and to require the use of current hardware to take advantage of it isn't unreasonable at all.
		Quartz Extreme hardware-accelleration via OpenGL is a positive and applaudable step to take - it removes a large workload from the CPU and congestion of the RAM bus, and it allows Apple to improve hardware through other means than MHz increases.

		Using three utilities he was able to turn Quartz Extreme off and on, and display how that affected processor usage and the compositing frame rate of the Quartz layer.
		Quartz Extreme has been turned on once again, off-loading graphics rendering to the graphics card (probably the NVIDIA GeForce4 Ti, in the demonstration machine), Becuase the graphics card is more efficient at processing graphics data the number of frames per second goes up and bandwidth usage of the processors drops dramatically.

	MacGamer - Get In The Game
		The key feature of PDF that sets Quartz apart from everything else is that it has support for vector graphics, which use mathmatical forumulae to represent lines and curves.
		With Quartz Extreme, Apple has kicked it up yet another notch: now not only is the GUI completely PDF and vector based, but now it uses OpenGL acceleration to composite all the graphics together.
		What this means is that instead of Quartz forcing the CPU to take the brunt of the work, pasting all the separate windows, images and graphics together into one unified screen image, the GPU can do all the work for it, leaving the CPU free to perform other tasks.

	Architosh: News > Apple's Quartz Extreme presentation at SIGGRAPH - PDF
		A diagram of the old Quartz Compositor (current in Mac OS X 10.1) demonstrates how various apps (2D, 3D and video) send their imaging into a buffer space, then to the Quartz Compositor and finally, after being composed (as in multiple apps and Finder all showing together), presented on your Mac's display.
		Quartz 2D and QuickDraw apps (2D), OpenGL apps (3D), and QuickTime apps (video), are all hardware accelerated from the initial windowing buffer space (surfaces) to the Quartz Extreme technology driven by the GPU which results in an accelerated Frame Buffering and presentation on the screen.
		All of this looks extremely exciting, as if Jaquar doesn't have enough features already, Quartz Extreme and Jaguar OpenGL are such huge improvements to the Mac OS that we are not at all surprised that Jobs completely skipped over this topic during Macworld's indepth presentation of Jaquar.

	Best explanation of Quartz 2D Extreme for a n00b? - Topic Ars OpenForum (Site not responding. Last check: 2007-10-22)
		Quartz 2D Extreme now does rastering on the GPU, where as beforehand, Quartz 2D did restering on the CPU.
		This was slow because the CPU still had a ton of work to do, and inefficient because the GPU had a ton of power that was not being used.
		The offscreen contexts are all converted to textures (this is done on the GPU, and much faster than uploading back buffers from main memory as Quartz Extreme did).

	LEM/Mac Musings \| Quartz Extreme Empowers the G3
		With Jaguar, Apple introduced Quartz Extreme, which moves the display processing from the Mac's CPU to the ATI or nVidia graphics processor itself.
		Although some users with older Macs, especially the beige G3, have attempted to use Quartz Extreme (QE) with an otherwise qualified Radeon PCI video card, the PCI bus just doesn't have the bandwidth QE demands.
		Entry-level Macs don't use multiple processors, and Quartz Extreme minimizes the benefit of AltiVec as far as the display system is concerned.

	Quartz Extreme - Applepedia
		Basically the idea behind Quartz is that OS X is using your graphics card to render the user interface, which leaves your processor free to do more useful things.
		Every time you move or resize a window on your Mac, Quartz uses the integrated OpenGL technology to convert each window into a texture, then sends it to the graphics card to render on screen.
		The graphics processor focuses on what it does best — graphics — freeing the PowerPC chip to perform more operations in the same amount of time.

		This hint is for you if you have a graphics card that is having problems with Quartz Extreme, and are having trouble disabling it.
		This means OS X won't use Quartz Extreme unless the card has a minimum of the value you specified.
		After the value is changed and saved, all you need to do is reboot and Quartz Extreme will no longer be enabled.
