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

So what if everyone of us experiencing the UI lag with rMBP is uploading a video which shows the lag, may be this could lead to more attention of this serious problem.

What's the point of uploading video? Apple is very much aware of the problem. This is not an isolated incident. Either they're going to fix it or not. And so far, it seems they have decided to not fix it. I'm returning my MBP retina tomorrow (within the return period) and will purchase a new one. I can pretty much guarantee it will exhibit the same lag. But I'll report back here nonetheless.

@poidet your post of HiDPI makes more sense.. I can see a big difference with and without HiDpi.

and why this issues only happen with retina, It is because Retina has HiDPI turn on by default.

and when you play games e.g. : Diablo 3. HiDPI is not being used so the lag isnt there. HiDPI only kicks in on normal ML navigation hmm.. thanks for sharing that.

Hope that we will have a new Intel driver to will optimise this HiDPI tech. 🙂

The point that, for example, I can't return it back because it's already too far from returning period, and what should I do ? and I'm not alone.. who spent big amount of money and get some real crap! Yeah i want that many people will know about such problem, why not ? I'm not a dump sheep, even if Apple thinking so! I want get feedback from Apple about that problem, and their plans. Will they fix it or it is impossible, if so then get back my money for that nice looking piece of crap.

About Safari problem or not.. I'm not thinking that this is Safari JavaScript engine problem, I believe that this all related to graphic card render process.

Apple really has problem with driver or with hardware, if so then they have to fix it!

But Apple official service far from me (300 km), and I don't want to going there for nothing... Here someone bring back their laptops to service, and in result they don't see any changes problem still there. If we will make more activity maybe they will see us ?

You are saying they know about problem, then why we don't know that they know ?

I know that they are thinking we need facebook support in ML :-) this is clear :-)

Well, I totally agree that this should be made a serious issue ...

I'm also using a rMBP (the fourth one now) and ALL of them had these UI lag issues! 😟

But: My MacBook (Late 2008, Mountain Lion) and my iMac (Early 2008, Mountain Lion) also show these "lag problems", although they are not that obvious there.

So it must be a software issue which is maybe increased by the rMBP hardware ... But at least, I think, they can make these scroll lags better (especially in programmes like Mail, etc.).

my macbook pro early 2011 is experiencing this lag too, and i was starting to wonder if there was any other person to confirm that this is only a matter of the software, which is serious, since that there has not been an update that actually tries to solve this and even though the softaware itself is wonderful (features hey added) the lag problem makes me really regret the purchase of it.

I assume this is not just a software issue. I had installed Lion on my rMBP and had the same lags while opening just few fullscreen windows and e.g. run mission control. So I think that this is not only a Mountain Lion issue.

Either on my MBP early 2011 or MBA 2011 I had never experienced such lags with Lion or Mountain Lion. Sure it is posssible that I was one of the lucy ones.

But as far as I could hear from rMBP users almost every rMBP is suffering from this lag. As mentioned before may be the hardware don't fulfill the retina requirements yet.

Well the point of uploading videos is not just to get only the attention from apple. As mentioned they are surely aware of this issue. Uploading a video is firstly a proof for the existence of a lag and secondly it is also getting the attention of the public. Then apple has to act on this issue when almost every rMBP user is suffering from this lag. It' also about image. Think about that.

Poidet, if you review the link I sent you, you'll see it's not just the rMBP. You'll also see that it doesn't happen in Chrome. That's what we call "isolating the problem." Yes, the lag is annoying, though greatly improved with the most recent update. But your Safari video is unrelated.

I beileve they are aware of the problem, they recently pulled a post I made to this forum because it violated thier agreement (I wonder if this one will get sensored too?), so either someone is watching or a bot found keywords they don't like. I'm guessing it was reviewed though, making someone over there aware of it.

The question is: Is it a hardware issue or a driver issue? If it's a hardware issue your screwed, and if it's a driver issue, are they working on a fix? IMHO they ARE working on a fix now. I seriously doubt Apple (Knowing about this issue) is not going to put pressure on Intel to fix the problem with the possibility of this becoming a PR issue that could blow up in their face. Apple VERY RARELY comes out and says "Hey, we screwed up, we are going to fix it" the only instance of this I can think of is the iPhone 4 antenna debaucle. They like to fix things discretely and quietly release a fix. They are not going to tell you thay are working on it. But still, it is good to voice your comlpaints and upload videos to show the issue exists so they are aware and can fix it. Just don't forget to upload a "Hey it's fixed!" video when they do.

It's not unlike computer companies to release things that are not 100% due to tight deadlines and then continue to work hard on issues that pop up (Basically using the general population as thier own QA team) Let just hope that this is one of those times and that the lenth of time it is taking to fix it does not denote a bigger problem.

I think I'm encountering the same problem as you, but on a late 2011 MBP (now with 10.8.2 and before with 10.7.4) : most of the UI effect are lagging and pdf viewing within Safari is just terrible.

As reported one temporary fix was for me to download gfxcardstatus and to only use intel HD 3000 GPU. (But this don't work for external display)

Another thing is that the GPU memory of the second GPU (amd 6750M) is full contrary to the memory of the intergrated one (when I switched back).

There's probably something wrong with that, and no way to fix it with only nvram/pram reset.

May be we have to look at the GPU memory usage (in developer tools?), but until then I didn't find anything to manage the vram usage...

I have also the same issue on my base MacBook Pro Retina. It is not that much on 3 fullscreen Apps, but if I open a 4th fullscreen App it became laggy on Mision Control and the Intel HD 4000. But I have no lag if turn off auto switch, on NVDIA GT 650M.

Maybe Apple can fix it bit, but I think the Intel graphic is not powerfull in enough for the Retina Display.

Sorry for my English

Best Regards

here my 2 cents . i don't own myself a rMBP , but i was also supprised about that borring lag , in PDF mainly.

i just tryed it in different store in France, and all the same running 10.7.5.

I own an 11 MBair 2012 with a thunderbolt display, with about the same amonth of pixels than rMBP and it work smoothly.

So i'm pretty sure there is a software issue , nothing to do with the Hardware. Something sure when Apple use Nvidia chip instead of AMD Radeon they always are facing issue at start. Guess it will improve in the coming days or months.

This is a very serious issue. Smooth animation is the main reason I use a Mac.

All animation on Retina MBP is broken.

Full of glitches and extreme lag. Expose, Mission Control and Spaces is simply broken.

If this issue is not resolved, I will be forced to ask for a refund, and buy an older Macbook Pro.

I feel your pain, OmSolari. Unfortunately I don't think you'll have your fix within your return deadline. I was in your same position a month or two ago hoping for the same thing. What's more, once you get used to computing at retina resolutions, anything else looks like GARBAGE, including all other Macbook Pro models. I wish I would have waited a year to buy this so that I wouldn't have become acclimated to the retina display, because honestly, the fluidity of OSX is completely wrecked right now. Apple's quality control right now is worse than any company I've ever seen. The expensive Apple Care customer service is awful, Safari is broken on half of the websites I visit, and navigating OSX is clunky. It's like they've never used their own products. It's also like they never look on their own forums, with the exception of monitoring profanity, which they quickly remove.

Aren't you being just a little hyperbolic? Aside from the lag when going into MC for the first time in a few minutes, this rMBP and Mountain Lion are far and away my best computing experiences in a very long time. I haven't used the rMBP with Lion so I don't know if the lag was there then (mine came with ML preinstalled) but if there was no lag then, I'm confident Apple will get it fixed in a x.x.x release.
