    I know that some of you are still on the fence, wondering about the lag issue that's been so widely reported on this forum and whether or not it will be fixed by Mountain Lion.

    Well, I'll be uploading some videos to alleviate some of the worries. Links will be added below as I upload new videos:

    If there's anything specific you'd like me to demonstrate, I can try to take a video of whatever it is you want.

    I'm running Mountain Lion DP4 with all the updates applied on a 2.6GHz/16GB RAM Retina MacBook Pro and web page demonstrations will be done in Safari. I will not be installing Chrome due to the reports of it causing crashes.

    Thanks for testing this. Do you know if the 2.3 ghz version will perform just as smoothly?

    Glad to be able to help!

    I don't think the CPU will be the bottleneck for general tasks like web browsing, so I would say that it should perform just as well.

    The difference between the 2.3 and 2.6 (they're both plenty powerful) is barely noticeable even in benchmarks, so it's not likely to make a noticeable difference in real-life usage.

    I have the 2.3/8/256 and I have no lag at all everything is smooth.

    Could you please do it in 1920x1200 for facebook and theverge and general mission control stuff in ML dp4 ? The best could be to use quartz debug and frame meter to measure the fps like in Anandtech to see if there is a difference between best retina and 1200p.

    You're going to have to tell me exactly what to do- where do I get QuartzDebug?

    EDIT: OK, looks like I'd need to install the developer tools. Sorry, but I don't have the time to do that right now. Nonetheless I've made a video with your requests incorporated and the link will show up in the original post once it's uploaded :) Hope this helps you!

    It still seems hard to tell via the video, maybe based on the uneven framerate/handheld nature of it. It's just really odd that we get this lag on very powerful computers but I can load any page on my iPad 3 and have not a single issue even when scrolling as fast as possible down a large page.

    I hope ML takes care of most of the lag. I am nervously anxious for mine to get in.

    Thanks for everyone's thanks! :)

    Unfortunately, I left my video camera somewhere else and the only video camera I have on-hand is my iPhone 4S, so I can't get better video at this time.

    Still, having video is better than just text. People's opinions are just subjective and even with my slightly low res videos it's still clear enough for someone to make their own decision as to whether or not it's laggy.

    Nobody. If it can keep up at that kind of speed, then it can certainly keep up at a slower pace.

    I note down which GPU was used in the video's description. For most of the videos, I was solely using the HD4000. The 1920x1200 scaling video I just uploading has a mix of the 650M and HD4000- I clearly show when I change GPUs in gfxCardStatus.

    Thanks, I'm on a phone so I didn't really think to check the description. Also didn't see the latest vid.

    Two new videos have just been uploaded demonstrating the 1920x1200 'More Space' scale- please check the original post for the links.

    No worries :) I literally just got the 1920x1200 videos up so they probably weren't there when you checked.

    Thanks for the videos! Just out of curiosity, was the performance significantly bad under Lion?

    Thanks for the support everyone, and I'm really glad I've been able to help :)

    I can't say, as my rMBP was delivered without an OS installed for some reason. I was thus forced to go straight to ML DP4 (which I was planning to do anyways).

    Read about my ordeal here.

    Hm, that's pretty strange- I haven't been seeing that sort of lag on mine. Are you running ML, and can you provide me with the link to the website you're demonstrating with so I can try it out?

    I read that article too. As you can see in the videos posted in OP, it's not as bad as the numbers sound- when scrolling along Facebook at a normal pace the lag isn't noticeable at all.

    Sorry but concluding that the rMBP is a decent performer is plain wrong. We're developers and have been using the rMBP for a week and it's brutal. Every UI event is slow. It's choppy and unacceptable. We're running the latest DP of Mountain Lion.

    Window redraws, swiping into Dashboard, bringing up the Dock, maximizing windows, etc. All slow and choppy.

    This is a real issue. Buyer and Developer beware.

    I have the 2.3 and I have to say in Lion it's certainly not that smooth. It does however look much smoother using Mountain Lion. Looking forward to the update ;)
