Lag vs No Lag Videos
Everyone,
I found a video on YouTube showing the lag I think people are discussing. This is on a 2.3 GHz version of the rMBP w/ 8 GB RAM:
http://youtu.be/uixeNzzJBXQ
I believe this person was using a screen recording program, so I'm not sure how much overhead that adds and whether that could skew the results of what you are seeing on screen.
I took an actual video recording of my screen using a DSLR, to eliminate any processing overhead that a screen recording application may add. I scrolled through George Takei's Facebook timeline, which has a lot of images and comments, as well as theVerge.com which showed the choppiest scrolling in the above video.
I quickly shot off this video using the automatic settings, I wasn't going for a technically perfect video, so please forgive those shortcomings. However, I think you will see when comparing both of these, I am experiencing nothing even remotely similar to what is shown in the first video.

The only discernible differences between my RMBP and the one in the first lag video is that mine is the faster 2.6 model with double the RAM (16 GB vs 8 GB). Both machines are on 10.8 Mountain Lion using Safari 6. The other thing I did differently was that I pre-loaded the web pages to eliminate any lag associated with page or image load time. This is not something that was done in the first video, and the lag seen in that video may have something to do with the fact that the pages and images were also loading while the pages were scrolled. Pure conjecture on my part.
So as you can see, I'm not making this stuff up. I just don't see the lag that others are seeing and experiencing.

Try change the scale of a window, when the window is large, you will notice the lag. Try to hide or unhide the left pane of mail app.
Are you new to the Mac? Resizing a busy Safari window always shows lag and has for years. I can see lag resizing a Safari window on my Mac Pro at work - this is not a good test.
If you want to see a good test of what the RMBP can do, check out my video:

Scrolling Facebook and theVerge, both previously identified as "laggy" while simultaneously playing three videos - two on the main desktop and one full-screen 1080p in a separate Space. Transitioning between spaces, launching mission control, scrolling in both of those web sites - no stutter, no lag, nada, nothing.
Another video from someone else showing similar:

To those who are experiencing choppiness or lag in the UI, I suggest you spend more time troubleshooting and less time starting threads about hardware problems that don't exist.
I have been using Mac for couple of years. Try resize a non-busy window, just open the Safari and open a blank page then resize it.
Absolutely no lag whatsoever resizing a Finder window. I just tried.

Thank you!
I'm sure this lag thing is a myth, my rMBP is smooth as butter.
I have had several MBPR, both the base CPU with 16GB RAM, 256GB SSD. All of mine have lagged on Facebook especially....did fresh Mountain Lion installs on them both. Lots of lag on this thing....then I use my iMac and everything is smooth as butter....
As far as troubleshooting where do I begin when this happens on fresh install?
I still love the Retina Macbook Pro...I've gotten used to the lag but it's very annoying at times.
