A little tip :
The line used on a terminal
This changes the duration of the animation.
If you set 2, it's really long and it you set 0.01, it's only 2 FPS.
defaults write com.apple.dock expose-animation-duration -float 0.15
And after this commande, type this to restart the Dock :
It's not a solution, it's just a little tip who can make the LAG more... acceptable...

I've bought yesterday rMBP and intalled ML.
Same problem with UI experience... very slow in Mission Control... inaccettable for € 2.299...
I've an MPB 2011 (with ssd Vertex 2 and 8GB ram)... no issue with ML or Lion.
Apple.... what are you doing ?
Currently Being ModeratedAug 5, 2012 3:01 PM (in response to dsciel)
I have the same problems.
I am coding in XCode and Sublime Text 2 (Text Editor). Scrolling in any of them, especially Sublime Text 2, is a pain in the ***. The lagging when scrolling when the windows is maximzed is unbearable. Its probably down to like 10-15 FPS or something.
This is the first time I am dissapointed after buying a Apple product.
If there is a fix for this I wouldnt care so much, but it feels like its way to many pixels for the GPU /CPU to handle.

No fix right now. Most probably problem is HD4000 driver or (I don't hope) architecture...
I've forced to use nVidia GPU and problem gone almost completely.
I don't want to use nVidia ever for battery duration. Next wednesday I'll go to Genius Bar to represent the problem but I'm sure they already know it.
Another time I'm doing beta tester for free...

Problem is a lot of people aren't experiecing any lag at all, a friend of mine has a retina MBP too, the chepaest one, and we never saw a single lag on his computer. And he did not tweak the graphic card nor something else. Just working fine out of the box.
Maybe i should do a clean install, apparently some people could fix this with a clean install (i read that on a french board...). Anyone tried it?

I tried 2 clean installs. There was no any lag but when Safari was opened or another software, Mission Control lagged... So, it didn't work for me...
Currently Being ModeratedAug 6, 2012 3:02 AM (in response to yannick-sker)
Yes I did.
Scroll problem, lag problem using Mission Control persists.
Clean installation of Mountain Lion didn't resolve my problems.
I've installed 2 times Mountain Lion, 1 from a bootalbe USB key created by myself from installer downloaded from my old MBP;
2nd times I've installed ML from Apple server directly but in both times I've the same problems...

my macbook pro 13 mid 2012 without retina display is laggy, too. animations are not smooth and very choppy. also safari crashes randomly! hope for a fix soon

As yannick-sker says not all of people has lag scroll/ML/other problem and this is strange.
Hardware is equal and software too... why I see lag and other not ?
In your case you have a different Mac and I can't say nothing about...
Until now I've read a lot of forum pages about this argument but without solution.
Here there are some different dicussion on retina MacBook Pro but I've never read solutions/fix.

i have absolutley no lag at all on my MBPr.
i have heard a few folk reporting this but it looks like it must be a bad batch.
if so apple should exchange it for a new one in the apple stores.

What specs do you have?
Wondering if its only lag on the 2.3ghz versions. I have a 2.3 and it's laging like there is no tomorrow. Try opening a long (300 lines) text file in Sublime Text 2 and maximize the window. The kind of scroll lag I get when I do that is unbearable.

Nvidia GT 650 1024mb
Currently Being ModeratedAug 6, 2012 7:49 AM (in response to stevo_c)
Most probably problem affects only 2.3/8/256 (baseline) model
Currently Being ModeratedAug 6, 2012 7:51 AM (in response to Montegentile)
Thats a pain... then Apple wont do anything to try and fix it. I Guess.
If I new that this was a problem I would have bought the 2.6 ... Hmm...
Currently Being ModeratedAug 6, 2012 7:58 AM (in response to bobmoff)
Do not hold any regrets: i've got the 2,66 and it's laggy, much more than some 2.3. The answer is not here eiher.
