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.

    16MB to draw a window?

    So it takes a video card with 16MB of VRAM to draw a pretty window and buttons?

    RE: 16MB...

    It doesn't take 16MB to draw ONE window, it takes that amount to draw many of them. A window is a bitmap, the size of that bitmap takes up the same amount of space on a video card whether it has pretty graphics inside or looks like a Windows 3.1-era window. It doesn't matter, all the compositing engine sees is a bitmap.

    The amount of VRAM required is because Quartz Extreme is a very innovative (but bleeding-edge, hence the high video card requirement) method of doing window drawing. Nobody's done this before, Microsoft's talking about it with "Longhorn", but they're a few years away from getting something real. The benefits will only get better - trust me, Apple is looking foward here, not backwards. I'd rather they do that than stick with some outdated 80's-era window-drawing methods in order to make sure people with Powerbook 100s can still use it...

    Or 3 month old iBooks...

    Does this mean my almost new iBook 600 with 8 MB Rage 128 Mobility will not work with QE? If they knew QE was coming, why did it take so long for Apple to put 16 MB Radeon video cards in the iBook? It's not like they were unavailable even then. I sure can't upgrade the video card (at all) or my iBook after only a few months?!? Don't get me wrong, I want Apple to push the envelope, but I also expect new (a few months is pretty new to me) hardware to be able to take advantage of a key feature of the new OS X Apple wants me to buy. I guess 10.2.x can wait until I buy a new iBook next year.

    RE: Or 3 month old iBooks

    The lack of video ram doesn't mean that you won't be able to use 10.2, just that Quartz won't be accelerated using your video card. Your iBook only has 8 megs of VRAM because it's a consumer device. If you wanted bleeding-edge technology to work with your computer, you should have bought bleeding-edge and gotten a powerbook. Apple kept the video system toned-down to keep the price down. You should know that.

    hmmmm okay

    i could care less bout graphic acceleration etc im just..... okay. is this longhorn beffore longhorn? when i heard about longhorn i almost spit myself. 3d desktop, animated folders spinning openening and closed warcraft 3 characters running across a 3d based desktop system, mad interactive 3d desktops with live 3d links drawn on parts of art, endless texture size and support. granted microsoft will pull this off half assed but the windows artists will pick it up and turn out eye stunning art. from speeding through the pdf it totally looks like you can have a complete 3d open gl os in quartz? was this newly developed? will apple move to a 3d very cool animated os aka browsing system? imagine particle and light effects zipping around, pixie dust chasing your mouse etc. i guess what im getting at is thats nice apple beat M$ at longhorn and this is a 1st BUT if THEY do not MAKE a 3D desktop 1ST M$ WILL get the credit for really IMPLEMENTING it. will apple change aquas graphics to 3d based textures? i would just really like to see them do this and run with it otherwise M$ will just suck the cream out of there filling as usual and this will be just another apple 1st ""hush hush"" microsoft DID ""hurrah! hurrah!""

    re: iBook 8MB VRAM

    "The lack of video ram doesn't mean that you won't be able to use 10.2, just that Quartz won't be accelerated using your video card.

    Bullcrap they did: they kept the video system "toned down" because they were deliberately trying to make the powerbook seem like a better system. Exactly how much do you think the difference in price from 8MB to 16MB of VRAM would add to the system component cost? Don't be crazy - Apple is playing the same games with these systems as ALWAYS. They can't really justify the prices of the high end systems, so they stack the desk by building 2/3 of the consumer system that they could have built for the SAME PRICE.

    quartz

    They probably had to make today's modern- aka Geoforce 4 or better video cards do some of the work, since the processor speed only goes up in speed bumps once or twice a year, unlike the pc side that goes up in gigahurtz speed in a years time. It will offload more work this way so that the slower cpu's can do more work doing other things and hence make the system faster because there ain't going to be any big leaps of cpu power anytime soon, by that i mean at least 500mhz (1.5Ghz) or better. they should have been at least 500 mhz faster according to the laws of Moore!
