I just found this neat little app at Marc Liyanage's site that shows you if your video card is using Quartz Extreme. Thanks to Marc for providing such an useful tool (along with his MySQL, PHP, and other packages, as well!).

Other ways
I think these are other ways to tell if QE is active:
Other ways
The cursor shadow thing is not a reliable indicator. Many users reported having the shadow even when Quartz Extreme is not active.
Other ways
And some users (like me) have a Quartz Extreme accelerated display (or several accelerated displays) and no mouse shadow.

This util becomes even more useful with <a href="http://arstechnica.infopop.net/OpenTopic/page?a=tpc&s=50009562&f=8300945231&m=7390915135">this tip</a> from the Ars Technica Mac forum, which allows those of us with PCI cards (still need to meet the VRAM requirements) to enable QE. There are a few anomolies, but many tasks are indeed faster.
ok so now what>
Yeah so I tested to see if QE was enabled and apparantly it is not.
Even more useful...
I can confirm on that the cursor does NOT have a shadow on a Grape iMac 333 with clean install of 10.2, not running QE. Conversely, the cursor does have a shadow on a 15" LCD iMac with a clean install of 10.2 which IS running QE.

In the Configuration.plist file (/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreGraphics.framework/Versions/A/Resources/), where you edit the file to enable QE on a PCI graphics card, you could probably also modify the minimum amount of vram required to run QE. The lines in question look like this:
Not fully hogwash
"BTW, the cursor has a shadow thing is just hogwash. I don't know where this started, but I had a shadow (+white border) before enabling QE. Stop the madness! :"

It's no surprise that QE is enabled on my TiBook. But when I attach an external monitor and run the checker app again, neither monitor has it enabled. Could that be right?
results on PowerBook G4
A possible reason is that a monitor needs so much video ram to produce the colors needed for the display. That is why the cards with more memory have better color. With quartz extreme, the minimum amount of ram needed is 16 to run. While having two monitors, it is splitting the video memory.

I get the same behavior on my Rev B.

I quote from <http://www.rutemoeller.com/mp/ibook/ibook_e.html>:
So Now What?
Ok so I run this app and find out that my QE is not enabled...what do I do from there to get it on? Is there a setting that I need to turn on or do I just need to buy a card that supports QE?
Cursor Shadow Distinct From QE
A shadowed cursor is completely distinct from whether your machine is running QE. You get a shadowed cursor if your video card driver responds YES to a system call asking whether the card supports a hardware cursor. This has nothing to do with whether you're running quartz extreme, except in that most of the cards that support hardware cursors also support QE. |
