Just to add a "me to" to this report. Late 2008 MacBook Pro, and I have exactly the same choppy spaces transistions others seem to have.
Is there a way to report this to Apple ?Mac Book Pro (late 2008), Mac OS X (10.6)
Currently Being ModeratedAug 29, 2009 9:31 AM (in response to ChrisJones051073)Strange. I have the late 2008, 15" MBP, 2.4 GHz, 4 GB RAM. The animations are, if anything, better than ever. I am running in the low performance graphics setting. I wonder what the difference is in our machines?

For me it is just switching between difference spaces has a slight jerkiness to it. Nothing terrible, just under 10.5.8 it was VERY smooth, so it is noticeable on 10.6 ...
I don't seem to notice problems with animations anywhere else, just in spaces...

Currently Being ModeratedAug 29, 2009 10:53 AM (in response to ChrisJones051073)For me the animations appeared very smooth on my MacBook Pro when running 10.6, but they were very obviously much choppier than before on my iMac. Animations on my MBP ran smoothly with either GPU, so I don't really know what the deal is with the iMac (other than perhaps the higher resolution), although animations were smooth with 10.5.8.March 2009 24" iMac 2.66GHz, mid-2009 15" MacBook Pro 2.66GHz, Mac OS X (10.6)
to add to my earlier posts i'm getting trackpad problems. sometimes it doesn't work. not sure why its been working fine now. before my isight wasn't working either but it worked after rebooting. this os has got some problems they need to fix.Macbook Pro Unibody "15 (Late '08), Mac OS X (10.6), 2.4 Intel Core 2 Duo, 4gb DDR3 RAM, Dual Graphics (9400+9600m GT)
Currently Being ModeratedAug 29, 2009 1:23 PM (in response to Hasan_Rizvi)My animations were fine in 10.5.8, and some a quite choppy now. Spaces is a bit, but it's most noticeable entering time machine, which looks very choppy now and was totally smooth before.
I am running a 2009 2.66 Quad Core Mac Pro, and my 640GB system drive has 432GB free, so it is definately not a hardware issue.Mac Pro 2009 2.66 Quad
Yep, you can add me to the list. Just check out the preferences for Finder - swap between the various options and you can see the choppiness / sluggish animations. In 10.5.x these were silky smooth. Also, Spaces and Expose are all choppy too. I'm running a early 2008 MBP 2.4ghz, 4gb RAM, 250gb HD, GeForce 8600M GT 256mb so not exactly low-end.
I read about the quartz extreme enable / beam sync disable trick elsewhere on these forums; neither of which work.Macbook Pro, Mac OS X (10.6), 15in | 2.4ghz | 4gb RAM | GeForce 8600M GT 256mb | 250gb HD
All animations and scrolling took a big hit for me going from 10.5.8 to 10.6 on a Macbook Air (Geforce 9400M). Using Quartz Debug to disable beam sync brings things back to how they were under 10.5.8. Without disabling Beam Sync, the performance is not just "worse", but embarrassingly bad.
What happened!?Mac OS X (10.6)
Currently Being ModeratedAug 30, 2009 10:02 AM (in response to Phill Horrocks1)Did you try disabling Beam Sync via the command line (plist) or the Quartz Debug application? I had success with the latter (but only while it's still running) but not the former.Mac OS X (10.6)
Currently Being ModeratedAug 30, 2009 11:13 AM (in response to Charles Conway)Hi,
No, I had not tried disabling beam sync. Doing so does seem to improve things a bit, although there is I think still a hint of jerkiness.. Thanks for the tip.
b.t.w. what is beam sync ? Couldn't find much info on it ...Mac Book Pro (late 2008), Mac OS X (10.6)
Currently Being ModeratedAug 30, 2009 11:18 AM (in response to Charles Conway)Hi,
Found a performance comparison of 10.6 to 10.5 on phoronix...
which is interesting as they also find major graphics regressions, although in other areas things are improved. They also hint that Apple are aware and working on it. Do hope so as so far these really spoils the "OS X" experience...Mac Book Pro (late 2008), Mac OS X (10.6)
Currently Being ModeratedAug 30, 2009 7:05 PM (in response to ChrisJones051073)Good find on the Phoronix article! They did indeed find significant graphics performance regressions that Apple is evidently aware of. Here's hoping that this gets addressed in the next point release (or sooner)!Mac OS X (10.5.7)
Currently Being ModeratedAug 31, 2009 10:20 AM (in response to ChrisJones051073)Probably the simplest explanation of beam sync is that it's supposed to reduce "tearing", where something is moving and e.g. the bottom half of the screen updates first so it appears that the object is "torn". Sometimes also referred to in games as "vertical sync". It basically delays updating the screen until the entire new image has been calculated, so you don't have part old image and part new.Mac OS X (10.6)
i have it too on a unibody mbp 17" 2.9ghz 4gigs ram 320gb 7200rpm drive, i doubt its hardware because spaces on 10.5.8 was smooth as silk. I noticed it degrade on 5.7 and got better than ever once i updated to 10.5.8 (which was lovely) now its messy again. anyway turning of the vsync in quartz debugger is ok and it does makes it less laggy but also makes it tear. Then instead of it being an isolated spaces problem it becomes a tearing issue for all quarts enabled effects like expose desktop showing app minimising etc ...to me thats not nicer thats just making something worse haha.
regardless i think having it set to default is the smartest option because then at least you will know when it has been fixed
