Dec 10, 2012 6:17 AMby cbs20,That' what I was thinking. But, I read that Apple had pulled that update from its servers. I had updated when it was first released in November and then did research after experiencing problems and found out others were having problems after updating. Then people were saying the update wasn't available anymore meaning Apple had pulled it from the servers. When I read this I searched Apple's support downloads page and the update wasn't there. After reading about an update on here (today) I checked the support downloads page and the update is back on, but still contains the same description and the same initial release date.

Dec 10, 2012 11:23 AMby TheMusicProdigy,You know what guys, I think you guys are right, because I jus reinstalled ML 10.8.2 and it probably didn't contain that update and now for some reason maybe it popped up , anyways the description said that it addressed gpu performance I think it said something about update 2.0 or something like that

Dec 11, 2012 11:12 AMby Wayne Chin,Seriously Mauro, what's the point in venting? And you really think Tim is in charge of creating this laptop? This is a respectable thread with serious inquiries about the retina MacBook Pro. I've gone through 3 motherboard changes myself, but you don't see me venting. You either go and get a refund, wait patiently for a fix, or do as I did, got Apple to replace my unit. Simple.

Dec 11, 2012 1:49 PMby jcbigears,That solved my problem too! I've testing my 15 inch retina MBP with multiple applications and so far it seems to be fixed. Everything is smooth again when on the NVIDIA card.
Here's the instructions, with a little more info:
The fix involves deleting 2 preference files.
1) Macintosh HD - Library - Preferences
(note that this ISN'T the finder-go-option-library, but the root directory library folder)
Delete:
com.apple.windowsserver.plist
2) Finder - Go - Option - Library - Preferences - By Host
Delete:
com.apple.windowsserverxxxx.plist
3) Then, perform a PRAM reset.
- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys
Can you all try this fix and please post if it works? It would be fantastic to get some feedback to see if it solves the problem.

Dec 11, 2012 3:13 PMby biyom,I just experienced something interesting. I downloaded SetResX and adjusted my interface resolution to 2880x1800. Everything is too small but the lag is completely gone. Previously I had some of my applications set to "open in low res". I changed these settings back to original to make sure.
Can you try SetResX and let us know if you still have the lag or not? I guess It'll be very helpful (If you confirm that you have no lag after switching to 2880x1800) to the people who is trying to find the reason of the issue.

Dec 11, 2012 10:03 PMby poidet,what exectly resolution did you use ??? with or without HiDPI ?
in 2880x1800 (not HiDPI) safari works well and of course webkit works faster even in that resolution, but we should not measure like this, i could show the video about lags and strange behaviour with and without HiDPi

Dec 12, 2012 10:07 AMby TheMusicProdigy,How do I disable HIDPI ? anyways I don't think I have it enabled, If I set res to the 2880x1800 the lag is less noticeable but it's not gone, for instance try to extend a window from the corner ( resize it ) to me that is sluggish so I really think an update is required
anyone else that can share their experience?
