Yosemite performance still bad on the Haswell MacBook Pro

:(

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

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 ?

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.

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. :)
