    :(

    Scrolling is still stuttery and overall the system just isn't as responsive as it should be considering the specs.

    Is it the one with the M370X?

    13" rMBP with Iris 5100. People were saying 10.10.4 apparently fixed it, but nope.

    Hmm. I don't really find my Iris 5100 on my late-2013 13" i7/16/512 to display much UI lag (except when running VMs in the internal display).

    Really? It lagged for me the first day I got it. I actually noticed it. I should have returned it when I had the chance.

    If the UI is laggy for you, I would suggest going to System Preferences>Accessibility>Display and enabling "Reduce Transparency". Let me know how that works out for you. :)

    It kinda helped, I just wish Apple would update their graphics drivers....

    Doesn't really lag for me, unless I have a VM running (in the internal display) or when I've a ton of windows open and try to open Mission Control.

    On a side note, my 13" rMBP is in clamshell mode most of the time, with a Dell S2240L 1920x1080 display connected via HDMI, and it never lags there.

    Yeah I always use the internal display.

    So how many Tabs and Windows does it take before it starts lagging ?

    Tabs - doesn't matter. It's considered as one window.

    Windows - normally about 5+ windows.

    Did you try resetting PRAM/SMC? There has been some evidence that the power management sometimes starts doing weird stuff and that results in lower GPU performance.

    Likewise here, I've never seen the lag. A few days ago I ran 20 windows on a base retina iMac running 10.10.3 and there was no Mission Control lag.

    On my 2015 top-spec retina MBP (also on 10.10.3), I just ran 15 apps and saw no UI lag whatsoever when using Mission Control.

    I have an early 2013 rMBP, 15"/2.8/16/750SSD and I have not experienced and UI Lag, and find Yosemite works really nice.

    I have a late-2013 13" i5, and haven't had any problems with Yosemite other than the wifi quirk. It runs tons of tabs and a handful of windows in Chrome like a champ. No noticeable lag here.

    Do the people reporting lag use scaling or have transparency on/off?

    It's laggy without scaling and at times even with reduced transparency and increased contrast. It's a night and day difference if you compare it to the performance of an Air. No stutter, lag, dropped frames or whatsoever on a two-year old Air.

    I own both 2013 i7 Macbook Air and 2015 top-spec MacBook Pro. Both are running 10.10.3, and I don't see any abnormal lag in Mission Control or any other app -- on either laptop. I have scaling and transparency at the default settings on both.

    Well, the Air is driving way fewer pixels... I have never experienced lag on Yosemite on my non-retina laptops either. But all my retina laptops lag on Yosemite unless, if capable, they are forced to use the discrete GPU.

    It's truly terrifying to run a 2015 13" scaled at 1680*1050 without disabling all of Yosemite's visual effects. The laptop is utterly impossible to work effectively on—even typing lags. The GPU just can't handle the rendering and re-rending of that many pixels, it seems. Then again, the 2015 also lags at default resolution too unless you disable transparency...

    It's not a GPU issue. It's an optimization issue.

    I can run my 2012 rMBP at 1920x1200 HiDPI without any problems, on a GPU thats around 2x slower than yours.

    Don't worry, I created the thread that ended up on the front page of MacRumors calling out Yosemite's poor optimization for integrated GPUs. :)
