After 24 hours, no visible glitches.

However: As expected, with more processing, the GPU in my 12" Rev. c is running hotter than usual. Since the GPU it by far the hottest part of the insides already, it's flipping the fan on more often than is... ideal, shall we say.

Going to leave it on for another day or so to see how things go. After that, I may do a couple of battery life tests, enabled/disabled. I have a feeling it's draining a bit more than it should be...

EDIT: Executing the command did not have the effect of listing QE2D on my system profile. Do you have to reboot?
A logout is required, not a reset.

Thanks for that post, I was considering turning it on, but my fans already go nuts and I don't know if I can deal with them being louder. I can wait until apple turns it on, I don't want to mess up anything in Tiger since it is working just fine now.
 
I've enabled it also, but honestly I can't see the difference with it on/off. I'm running it on a 15" PB 1ghz, and 1 gig RAM. Is there an application I can use to see some stuff?
 
I enabled it on my B&W, and actually see a marked improvement in video playback as well as a slight improvement in the GUI. I'll enable it on my iBook later today and post the results.
 
I want to make sure my card is compatible with Quartz 2D Extreme before I enable it. I'm using the GeForce FX5200 that came with by 1.8Ghz G5. I know the card is compatible with CoreImage, so does that mean it's also compatible with Quartz 2D Extreme?

If it's compatible with CI, it will work with 2D Extreme.
 
If it ain't broke, don't fix it.

Since battery life seems to be good and the fan doesn't kick in often, I'd say things are going well. Video playback has never been a problem either. Well, I personally never saw anything wrong with it, and I don't want to enable this just to find out. :eek:

It's not a case of being broke... I really can see the difference in regular usage; silly things like when the CPU is busy with other tasks, the Dock magnification is still smooth. Perhaps it's not required for those with G5s, but for Powerbooks it's a trade-off. Either you use both processors together, or you use the G4 alone for graphics rendering. It isn't ideal, but better for performance.

I'd like to see this perhaps tied to the Energy Saver settings... in the meantime, an Applescript will have to do ;)
 
Does this setting stick after reboots? I notice that Quartz Debug seems to detect the state as disabled when it starts.
 
The help for Quartz Debug indicates that it is persistent across reboots, but I've read from others that it's not.

Anyone help?
 
I enabled Quartz Extreme 2D on my new Power Mac (dual 2.0 G5) with Radeon 9650 tonight. To be honest, I did not notice any real difference.
 
I'm afraid to use this on my 12" 1GHz Powerbook with an Nvidia 5200 and 32MB of RAM. Why? Well, because now with Tiger, it already has to deal with CoreImage taxing it, and now it has to deal with Quartz 2D Extreme as well? My 32MB video card doesn't have the juice necessary to run CoreImage well. It runs, but its at the bottom limit of what is acceptable. Anyone with a 5200 and 64MB of vRAM don't need to worry.
 
Wow. I feel like this makes quite a difference on my machine. This baby keeps amazing me. I haven't had any glitches so far or video artifacts anywhere...
 
In a little test of my own (only using Tiger since this past week) I found a marginal difference with Quartz 2D Extreme enabled. Here's what I did:

I have a dual 1.25GHz PowerMac G4 (Firewire 800 version with 256KB L2 and 1MB L3 cache per CPU). I also have a retail Radeon 9800 Pro running in the AGP 4X slot and 1.5GB of RAM.

I used the Apple developer tools to turn off my 2nd CPU and watched a DVD movie in DVD Player 4.5. I ran the tool BigTop to monitor my CPU usage. With Quartz 2D Extreme enabled, my CPU stayed between 30% and 34%. With Q2DX disabled, CPU use was between 37% and 40%. With my 2nd CPU turned on, the difference was about the same only with slightly lower numbers in both cases.

So there is a difference but for me there was no noticeable change in the display -- it just took some of the load off my CPU. I did the single CPU test just to see what Mac mini owners or G4 iMac owners might see.
