It is possible to easily enable Quartz Extreme (QE) on G3s or G4s that do not have a QE compatible AGP 2x graphics card. The hack is described here. From some tests that users did, it seems that only the G3/G4 machines with 66 MHz PCI bus saw some acceleration. Machines with 33 Mhz PCI bus, did not. The hack would work only if you have a Radeon or a GeForce2MX+ card, because they share the same driver with their AGP versions (QE only works on Radeons and GeForce2+ — ATi Rage cards do not work at all with QE, with or without hacks). Also, please note that users who enabled QE on their unsupported PCI machines, had major artifacts on some applications, most notably iTunes’ visual playback (quite possibly because the PCI bus is not fast enough for what is required).
don’t you ?

I would think so. But how much memory is ‘enough?’ Does anyone know?
16 meg min
Why the hassle putting Jaguar on an old machine (besides for the fun of the hack)?
I consider it more fun to do current tasks with older systems, like video editing with an Amiga. Or desktop publishing with MacOS 6 or NEXTSTEP 3.3. I’m currently setting up an Windows 3.11 system to see if it is still capable for Internet browsing, multimedia (like MP3) etc.
BTW Jaguar runs very nicely on my iBook 700…
I’m a bit confused. I thought the GeForce2MX already supports QE ?
The hack would work only if you have a Radeon or a GeForce2MX+ card
Why would you need the hack if it is already supported?
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
Am I to interpret the ‘+’ sign in “GeForce2MX+” to mean any card greater than this card or is this yet another derivation in the “GeForce2” series…?

The hack enables QuartzGL on PCI cards – 10.2’s standard config allows QuartzGL only on AGP 2x cards.
Thanks Stew. I hadn’t gathered that from the article.
no problem- that’s what web forums are for 😉
> I hadn’t gathered that from the article.
The article clearly states “on G3s or G4s that do not have a QE compatible **AGP 2x** graphics card” and the title is all about **PCI**.
And if you had click the first link, it would take you to a page that explains more about what is required.
So, how long until Apple takes legal action to suppress this patch, on account of it keeps people from having to buy a new Mac? :^P
Well, many sources confirm that Jaguar is generally faster than 10.1.x even WITHOUT Quartz Extreme. Quartz Extreme (or QuartzGL as some in this thread are calling it because it uses OpenGL) is just a really, REALLY nice bonus.
As with 10.1, 10.2 is breaking compatibility left and right (think back) but most stuff is working. I also think that most of the software makers will catch up faster if necessary.
