2015 Macbook Pro's Intel Iris 6100 is so choppy in Yosemite

I have istat menu running with no perceivable gui lag on my 2015 rMBP. With that said istat menu isn't fully functional in the new MacBook but that's a different issue the dev is addressing.
Best is an incredibly subjective term, if you are referring to fluidity you clearly don't know what you are talking about.

According to MacTracker, the 2011 MBA has: Graphics Card Intel HD Graphics 3000. Was that 2011 a typo?

Well, just tried the laptop out on a 1080p external display and it is unusable. So laggy I can't do basic work. Taking the laptop back for an exchange.
I can't believe it but this totally eliminated the jittery GUI! Just shows how badly Yosemite is optimized.
Yeah, it fixed it. I'm really hoping they optimize the software. I am chromecasting a video in my Chrome browser and when I try to render pages, you can kind of see a gray/white checkerbox that lasts maybe 1 second. It's weird cause you would think the 6100 would be powerful enough. I didn't have this problem on my cMBP. I was thinking of dishing out and getting a 15'' but that would require a significant more amount of money as it would require a dGPU. Not sure if there is an answer to this other than Apple optimizing Yosemite.
They are going to have to do something about it now that the paper thin macbook slouch is about to be released.
So, I am trying to do this (I have done it many times before).
App store won't let me redownload Yosemite saying that it's already installed on my computer. I have no problem redownloading it on the cMBP.
I get a crossed out circle when I try to boot from the USB when I reboot my computer. The cMBP has no problem booting from the USB.
Is my only option to go to the Apple store and ask them to clean install? I'm getting pretty annoyed with this machine...
It appears it may be due to FileVault being on. I wonder if this is causing performance issues. I only enabled it cause the laptop was new. Will turn this off. Will see if this improves performance.
And I can't install from this USB drive despite turning off FileVault and being able to install from it on my other mac. Any solutions?

In my previous mid 2014 rMBP (my first Mac) I enabled FileVault during initial setup and it remained stuck on "encryption in progress" and I couldn't turn it off or disable it and I think I couldn't enable the built in firewall with it stuck. In either case it annoyed me to no end so I wound up trying many different "remedies" I read online only for none of it to work. Eventually I just wiped the hard drive and reinstalled the OS. I did the reinstall per the instructions below and it was a cinch.

With my new 2015 rMBP I didn't bother enabling FileVault.
You might be wasting your time, I had done a clean install of Yosemite when it was released, it didn't remedy the jitteriness. FV is an interesting lead, I unfortunately don't have the luxury of time to do trial and error. The only thing that really worked for me so far is the contrast feature in accessibility.
I might do this. Or least wait until the new 15 comes out and squeeze the trigger. But that would be a long wait 🙁
Nope, Mavericks is pretty much buttery smooth. Tiny, tiny spikes of lag sometimes with many windows open, but far from Yosemite.

With all due respect, you cannot be serious. Yosemite is the worst OS I've used since Vista (or only considering OS X versions, Lion). Even prominent developers and press have complained about Apple's declining quality control.
Here's a very detailed roundup you can consult when time is appropriate.

Can you install Mavericks on those? I know that you can on the 13" because I have one myself. If you do get around to installing Mavericks, you'll notice the huge performance gain, along with (nearly) no lag.

i do not use file vault encryption. however to clean install i booted up holding the funny apple key + r. erased my hard disk using the utility then connected to wifi and boom clean install.
not sure if that helps you.

Man, I don't understand the problems everyone is having. My 2012 Retina 15" running on integrated doesn't have lagging problems, nor did my 2013" 13" retina with 5100 graphics....are you guys that anal or am I lucky. Maybe it just doesnt bother me, I suppose it looks slightly smoother with dedicated turned on, but nothing to write home about.
Sorry, this is not at all being @nal and it is certainly not a question of slightly smoother experience. We're talking MAJOR jitteryness, as in day and night GUI experience between Yos and Mav.
User experience seems to vary substantially but that is probably because of the differing ways that we use our machines. CLEARLY this is shoddy implementation of YOS and I blame Jonny boy 100% for his obsession with eye candy, even if it means sacrificing the overall feel. Shame because i was really impressed with Mav and this doesn't even come close.

yea....sorry I just don't see it, but to each his own... Mine runs smooth as butter.
Hey, I'm also having this problem with my new 2015 rMBP 13". Here's a link to a video I captured showcasing the lag: https://www.dropbox.com/s/w1k8lyhx1obex58/lagUI.mov?dl=0
I didn't do a backup restore, instead I cleanly installed all my software. So far only turning on high-contrast mode helps, but I'm not happy with such a gimmick since this is a new laptop and should be able to handle the UI and Yosemite just fine. I'm not a 100% sure if the UI lag was present from the start, I didn't pay attention to it then. So I can't rule out whether something I've installed has caused it or if it was present from the start.
I tried PRAM resetting a few times and many other solutions, but it didn't fix my problem.
Any idea when those are coming out? It would suck to use a hampered mac until then.
What's your source? What do you mean, it's been with us since Mavericks? Does anybody whether it's a hardware or a software problem? If it's software, why isn't it clearly fixable? And why is it only present in some Macs? (I presume most rMBPs are handling the UI and the OS just fine and without lag).
Seems to indicate it's a software problem. However, PRAM reset didn't work out for me, so I wonder if I'm just left with trying to reinstall the OS cleanly. That would take me plenty of more hours, of which I'm not happy about. I've already put many hours into trying to figure out what's wrong. Does Apple give out gift cards or something for problems like this?
That's what I'd expect, having updated from a 2011 MBA because of choppiness... What's a lemon? A badly preinstalled mac or what? An OSX reinstall would fix that?
I haven't made comparisons with other rMBPs, but I have got the impression that most people have it buttery smooth. What I'm experiencing just can't be normal.
I guess I should try this, but I really wouldn't like to go through all the hassle if not necessary...
My point exactly.
Ideas?

Honestly I think you got a defective model. I bought a base model 2015 13" and have no lag at all.
Remember that the Broadwell processors got delayed because they were having issues with getting production up due to it being much more difficult to fabricate. I believe they were having issues with producing processors that were fabricated correctly. You may have gotten a faulty processor most likely.
