    I have seen a few coments in other threads about 10.8.2 improving UI and Safari lag on rMBP. Given the number of people complaining about these issues I thought I would start a dedicated thread discussing whether there was any hope for a fix in 10.8.2. Has anyone noticed any improvements?

    I think there will be a lag until technology catches up with the display.

    Macro aslo mentions it in his review, http://www.marco.org/2012/08/26/retina-mbp-review , but does say it did not stop him from calling it the best computer he has ever used.
    I don't think the current GPU's can push that many pixels. Perhaps in a year or two.

    Thanks for the post. It's a good review and he does seem to agree with AnandTech. I should have mentioned that I actually purchased and returned a rMBP because of the UI and Safari lag. I found it to be annoying and atypical of an Apple product. I have been following the threads about the recently released 10.8.1 update and the soon to be released 10.8.2 update hoping that there might be a fix. I really did love everything else about the computer and if I heard tomorrow that the UI lag was improved by the update I would re-order the computer immediately. I was just wondering if people were noticing any improvements with 10.8.2?

    I don't think this issue will be fixed with a software update. In my opinion it will be fixed when a newer GPU is put in place. I could be wrong. I am not on a rMBP, and have only seen samples in the stores. It would not stop me from buying one, but at the same time, it makes me think what will be around in a year or so when I am ready to upgrade.

    I would be very interested to see a video of this "lag". It is like 24fps "lag" or plain good old stuttering while scrollings?

    I tried a store unit as well. Running on the discrete gpu did not fix the lag for mission control on the unit. If this is the case, it is certainly a software issue.
    Can anyone confirm?
    In two weeks or so i now it for sure :D

    There are certainly limits to what the hardware is capable of, but that doesn't mean that there's no room for improvement left on the software side.

    Also, there seem to be some weird bugs related to performance. For example: I got pretty mediocre performance with a windowed OpenGL application when running in virtual 1680x1050 mode. When I set the screen size to 1920x1200, performance was perfectly fine all of a sudden, even with the application window maximized. In theory, this cannot be.

    Video

    ----------

    I actually stuck things out hoping and hoping that performance would get better. Finally sold mine today and bought the non-retina version... it's soooooooo much faster it gets me excited to write code on a laptop again. The retina screen is amazing, but after 3 solid months of (attempted) use I have to say it's pretty much unusable unless you just have really low expectations for your computer's responsiveness. Drove me crazy.

    ----------

    Agree with this. It's not the hardware per se but the way OS X virtualizes the lower resolutions combined with the hardware. If you hack OS X to 2880x1800 it's very fast, as fast as the non retina macs almost. But then of course it's unusable because of eyesight.

    It's fixed!

    10.8.2 *does* fix the UI lag issue on retina macbook pros. It fixes it decisively. :D It's now as fast as my high-end 2011 Macbook Pro .

    I'm voting for this to be a software problem as well. The retina MacBook is packed with a very powerful GPU - I think it should handle this amount of pixels.

    But most importantly - it seems like there is too much variation from app to app - suggesting the coding has a great impact on the fluidness and lagging. Take iPhoto for instance, which is a somehow heavy app, but still runs smooth as butter. iTunes and Safari on the other hand, runs sub-par FPS on many occasions. When iPhoto can scrobble thorugh my entire photo library at 30 fps, I see no reason why Safari shouldn't scroll www.aftenposten.no at a decent fps.

    To quote what another forum member said about the case earlier:
    Also, I'm seeing great improvements on the facebook news feed after resetting the entire Safari app, deleting cookies, autofills etc etc etc. This also indicates bad coding.

    I'm not a pro though, so feel free to tell me where I'm wrong.

    i'm hoping this means the same for non retina macbook Pros from 2011 onwards.

    on Lion, my macbook pro 2011 (bottom end 15 inch) would never lag on launchpad or swiping desktops, or mission control. it was always silky smooth.

    im convinced this new Dock and the larger icons in launchpad are the reason why its laggy. and not silky smooth.

    so if apple have done something in 10.8.2 to bring down the strain on the gpu, then it proves its a software thing as much as hardware.

    again, i hope it fixes it on the non retina macbooks too, cause i love mountain lion outside of its issues.

    Are you sure? You're the first one from which I hear a so clear statement...
    I'm asking because I returned mine rMBP but I really loved that machine except for the lag issue. So the idea is to buy it back if they fix that issue.

    Could you try to check the frame rate while scrolling in safari using the Quartz debug utility included in the xcode software package?

    My rMBP used to score a very poor 20 fps on heavy sites.........A really smooth experience is around 50-60 fps.....

    Thank you very much

    I'm finding good results turning the stacks to show as folders and using Safari for web browsing. Not perfect, but much better than before. I've looked through several 'rMBP lag' threads, it really looks like a software issue. But try changing stacks to look like folders, made a big difference on mine.

    Definitely a software issue. My rMBP was a speed demon on Lion, with animations smooth like butter. ML induced the stuttering and lagging, so we'll see what 10.8.2 can do.

    I don't know what to say...on my rMBP the lag was present ALSO with Lion.....on safari I used to se 10-15 fps....actually on ML many things were improved.....not enough for me, but improved. Your experience is very different from mine...

    I loaded theverge.com on my brand new 2012 Air and scrolling up and down is significantly choppy here as well. Same with re-sizing the App Store window. When clicking the green button, it is noticeably choppy when resizing.

    I tried these actions on my girlfriend's MacBook Air with the same results. This is with 10.8.1, so it is likely a software problem.

    It seems that whomever made this video has never actually tried these actions on a non-retina computer, as you will see the exact same effect on non-retina Macs. This video is inaccurate FUD, plain and simple.

    *Edit* I also tried the site www.aftenposten.no, mentioned earlier in this thread, and yes it is choppy just like the others. This is a Mountain Lion issue, not hardware. It is likely exacerbated by the higher resolution of retina displays, but not caused by it.

    I made the video. And you don't know what you're talking about. Sitting here on a 2012 non retina MacBook Pro and it's literally 20-50 FPS smoother. It was smoother on my early 2012 Air too. The mac approach to graphics always hits intermittent lag and choppiness, but not like on the retina. On the retina it's just insanely choppy.

    I never said it wasn't smoother. I said it was present on even the most modern of non-retina Macs. It was not there with Lion. It is there with Mountain Lion. The logical conclusion is that it is a problem with Mountain Lion, and not the hardware.

    I can't agree more with you.

    And for those still spending time on the present-with-ML/not-present-with-L lag argument I would like to clarify it: The lag on the rMBP was present ALSO under Lion. I measured it with quartz debug. My 2009 13" MBP provided a smoother experience than both the lion-rMBP and the ML-rMBP.

    I don't know IF ML introduced the lag issue also on non-retina macs, but on the rMBP that issue was present from day one.

    ----------

    Thanks. It's (almost) a good news. Hope they'll manage to fix ALL the drivers related issues.

    Official 10.8.2

    It's out, can people with retinas report back? Is the graphics performance any better? Is it worth my returning my new non retina to get a retina? Inquiring minds! Thanks!!!

    ----------

    You actually have it backwards. The lag was even worse in Lion, slightly improved with Mountain Lion. But still unusable. Hoping 10.8.2 will fix it once and for all. The irony is I just sold mine last week and bought a non-retina 2012. That sucks.
