If the dynamic refresh rate does down to i.e 10Hz to save power, it would look like you're playing a game with 10FPS. Jerky and jumpy.

I am the guy who posted the first youtube video with UI lag. I have exchanged the machine twice, set up as new, downloaded all my apps from new. Still seeing lag. I guess it's a matter of how many apps you have installed in your system. If you install a lot of apps like I did, you WILL experience lag, no matter what. My video proves that.
I may still keep the laptop, because I really want a light machine. But the UI does lag. The more people know about this the better. If this gets known enough, maybe Apple will fix it. Apple will NOT fix it, if you guys keep sweeping this under the rug.
Here is proof from another macrumors user:

Oh another thing I discovered is that scrolling stutters in "Photos" like there's no tomorrow.

Fair enough. Frankly, I find this absolutely hilarious. Pay an ENORMOUS amount of money for something with the graphic power of a netbook (a cheap netbook, sorry). Of course, it's fixable (somehow). I own a 15" (haven't gotten it yet)
Haven't we been here before, BTW? Like a bunch of times, as I recall. Some ol.
Is there an explanation for why the 15" model has the inferior intel graphics card?
I don't understand why the 13" would have the Iris 550 while the 15" has the HD 530.

They decided to save some money to keep their profit margins even higher than they are.
It doesn't of course. It has really powerful separate graphics card. The problem is the switching between as 'so so' internal graphics card ( a little underpowered), with the external one. It never works all that well.
LOTS of people hate this arrangement, and just want an quality internal GPU, rather than an external/internal arrangement. Other will explain this in great length.....trust me
Also, this dual GPU setup is much more likely to have glitches and even failures. This dual graphics thing has been going on for years. Hopefully, this time things won't get really bad [doublepost=1480291606][/doublepost]
Wrong.

There's nothing wrong with including dGPU. You really need a minimal iGPU for UI animations. But in this case, Apple decided to choose iGPU which provides way below minimum performance for UI animations.It doesn't of course. It has really powerful separate graphics card. The problem (not the first time) is the switching between as 'so so' internal graphics card ( a little underpowered), with the external one. It never works all that well.

Margins. This is a quad core cpu within the same price range as Apple's previous choices of 15" model cpus (perhaps slightly cheaper), and it comes in at the same tdp. They simply cheaped out on it.
I think the stutter is something fixable by software. For me the stutter is reproducible in a few specifics spots and additionally happens now and then in Mission Control and when switching workspaces. In those cases it only happens on the first time though, so if I use Mission Control / switch workspaces again, the stutter is gone. Furthermore there are many fluid animations that seem a lot more stressing as opposed to just scrolling icons in finder, so I believe that this is not an iGPU limitation but just bad optimisation.
First time stuttering means exactly that iGPU is underpowered. The fact that it's smooth the second time is that data is already loaded in GPU RAM so it doesn't have to re-render some of the frames.
Haha didn't we establish that OP's video is not a good representation of the average user? Not sure why it's back up again. Some misconceptions:
1. Many users have reported no serious visible lag, with video proof.
2. If the lag was this serious, it'll be much more prevalent.
3. There are no Iris Pro Skylake chips that are actually out in the market. Probably no sufficient yield on those parts for Apple to use them.
4. Internal UI animations do not take that much graphics processing power.

There's only been one video proof where the user tried to disprove me but he did in fact also experience lag, when recording at the same time.
I faced the same lag on a 2013 15" rMBP on Iris Pro. The lag is attributed to the simultaneous recording using QuickTime. He did, in fact, face no lag when using his iPhone to record the video.

Ok, so far I have 3 users who have proof that the UI lags. You have 1 user with proof saying it doesn't lag.
3>1. Just so you know.
It's unclear if Intel can even produce the quad-core Skylakes with Iris Pro in sufficient quantities for the MBP.
Can you link any laptops that use that specific processor in your link? Or the 6770HQ?
Did you notice the last user is me? HAHA. I'm saying it's due to the QuickTime video recording.
Uhm okay, if trying it out myself doesn't prove so. It's okay! Thanks for the opinion.
The lag certainly is real. I am seeing it too and this isn't with so many apps open. Just basic Safari, Mail will probably do it.
On my old MBP 2011 (non-retina), it's buttery smooth even on the iGPU. Of course *that* iGPU cannot do Retina. But if Apple is pushing for a Retina display and using an iGPU that's a bit underpowered, that's an important enough thing to be looked at. I sure hope it's an OS driver or something that's the issue here.
I know under Parallels the lag's a LOT worse compared to my old MBP. IE or Chrome under Parallels the scrolling is really problematic.
Has anyone tried to boot through Windows Bootcamp to see if the same issue persists in Windows?

This gives me real hope. HD 4000 as per the Wikipedia link has about 163 GFLOPS and the 530 has 441. If indeed the HD 4000 has no stutter whatsoever, then it's just an optimization issue.

That's what I'm thinking. I mean, scrolling a heavy site like The Verge in fullscreen works without a single dropped frame. That website cannot possibly be less demanding than rows of icons in Finder, right?
They did before. They're apparently in use in a NUC now, but they are comparable to what Apple used with Haswell. Intel can be a bit slow early on, but this started shipping in the first quarter. These cpus came out a while ago, so I don't see the problem with producing quantities sufficient for a laptop that starts at $2400 (constrained by price). There's no reason to believe intel is that strapped at this point. We're talking about the 15" model, and there's no way Apple's quarterly "Macs" numbers break down in favor of 15" shipping quantities.
So you can't find anything besides the NUC? Ok.
By "making them before" I assume you mean non-Skylake chips? What's that have to do with the topic at hand, unless you're saying you'd rather Apple still use processors even older than Skylake?
That's a really disingenuous comment.
Apple used this type of chip in their last model. It ran for more than 2 years. Other brands barely touched them. This time Apple didn't use them, yet they've been out for a long time. If Apple wanted to use them, they would have placed an order. For the most part other brands stick solely to discrete graphics on their quad core laptops. There's no graphics switching, but their battery life is not comparable to Apple's claims.
