Q: Mountain Lion UI Lag on rMBP !!! (Let's Make this thread serious and hope for a fix)

My mid-2012 rMBP 15" is not happy either. I've been in contact with Apple, but they blame the author of the software (www.renoise.com) I experience.

I made this for Apple to show the drop in fps when the sw is fullscreen: http://www.youtube.com/watch?v=qvG6vWVcbnA

Then they asked if I could shot a video with my phone, because he didn't see the problem with the first one. I did and also rigged my (early) 2012 13" MBP with the same sw and same demo song to compare: https://www.dropbox.com/s/9af1f59rq1i0euy/2012-12-07%2013.54.55.mov

No fixes like, deleting files, resetting SMC and SwitchResX have worked so far. The developers from Renoise claims it support Retina display, so I'm kinda stuck (http://forum.renoise.com/index.php?/topic/36681-retina-lag-high-cpu-activity/pag e__st__25)

Could you tell me the software name which can measure you fps ??

Thanks.

• Download and install XCode (free on the Mac App Store)
• Launch the “Quartz Debug” app, located in /Developer/Applications/Performance Tools/

interesting, I have XCode but i don't see "Quartz Debug" could it be that in Mountain lion it's not present ??

Open Xcode.

Choose Xcode > Open Developer Tool > More Developer Tools...

Choosing this item will take you to developer.apple.com.

Sign in to developer.apple.com.

You should then see the Downloads for Apple Developers webpage.

Download the Graphics Tools for Xcode package, which contains Quartz Debug.

I did all of that but when I open quartz debug I don't know what to do :S

The update that came out yestersay for the WiFI issue for late 2012 macs also had an update in it for HDMI issue's, seems to have helped my situation with respect to the lagging and jerkyness

----- Search for Quartz ----

---- download the graphics tools bundle --

----- un check enable HIDPI

Enjoy

You might want to re-read what you have just written, 'un check enable HIDPI'

You havent fixed anything, only disabled the retina display (HiDPI)

Geez , I got rid of the lag  which was the problem  sooooo ... I fixed it

now unless you have a better solution ,go somewhere else with comments that don't add anything positive to this post

Ok kid, enjoy your MacBook Pro

You can also achieve the same effect by using the Retina Display Menu tool (http://www.reddit.com/r/apple/comments/vi9yf/set_your_retina_macbook_pros_resolu tion_to/) and choosing any of the resolutions without HiDPI written after them, as has been mentioned earlier in this thread.

Themusicprodigy... He is right, you no longer have a retina mbp... Now is a regular mbp with no cd. The idea is to maintain the high pixel density without the lags. I'm still waiting for 10.8.3, I hope that solve the problem

It's just a fps meter which I used to show the drops. Not a suggested solution.

I don't know if anyone here has ever tried this, but it seems that there is a solution :

FWIW, I did the delete windowserver prefs thing and PRAM reset, and it helped at first.  I even thought it was gone for a second.  Then I opened my usual amount of apps and windows (Safari, Chrome, Firefox, Skype, Mail, etc) and now the mission control animation is nonexistant. It's as choppy as before.  Also, even RIGHT after the fix with nothing open, iCal and Contacts exhibited the same lag as before when switching months and switching to fullscreen mode respectively.  Sorry, but I don't think this is quite the solution yet...
