Some 2015 13" MacBook Pro Users Complain About UI Lag

Serban said:
in the first version of the 15" retina MBP the problem is HD4000, so there the problem will not be solved
Only starting with HD5100 and Iris pro was enough power for gpu to sustain fluid UI

Mine also has a NVIDIA GeForce GT 650M and has had some issues with lag since day one. I always just considered that the price to pay for retina. But now there are newer 13" models without discrete graphics and they seem to perform better. This all just makes me want to wait a really long time before upgrading my Mac. Surely after everything has been on retina for several years (well it has almost been three already!) we will stop seeing issues. Until then I have to keep rebooting my machine to switch desktop spaces or use exposé without the whole system lagging apart at the seams. Can't wait for retina to be considered baseline because I'll never need anything higher resolution than this. My eyes can't discern anything better!
 
My one-year-old 13-inch Retina MacBook Pro runs like a stuttery piece of garbage after Yosemite.

Still deciding if I should just downgrade to Mavericks.
 
i have that lag on my 2013 15" rmbp, but its not that bad. its just when i click to open a new tab it lags and then switch windows
 
Hence why I would never buy a MPB with only integrated graphics. This is why I bought the 15" with the Nvidia GPU which is the only one I use. I have disabled the integrated one.
 
I get some lag when switching spaces occasionally on my 2014 15" while it's using the integrated graphics. When it's using the dedicated card it's fine (using 1920x1200 scaling).

I guess it's just too many pixels to render smoothly.
 
I have a 2015 I just bought a 13" rMBP. I have no such issues and I've been running the Yosemite Beta from day 1.

Best MBP I've ever owned.
 
Just bought the new MBP 13" with the low end processor but 16 GB RAM. I get the slight "choppiness" of the UI. I turned off the transparency, works fine. But, hopefully it's just a driver issue.

do you think i should reset my pram or SMC?

Doesn't help, unfortunately.
It is solely a driver + scaling issue (I have the late 2013 with the same Nvidia card).

I really dislike, how Apple handles high resolutions: pixel doubling and scaling back does always mean extra load to the graphics system.

Apples implementation of scaling is more concise, but Windows is using some sort of vector engine for their UI and it handles even 4K resolutions on integrated graphics easily.

Interesting, I have the same setup as you but I disabled the Nvidia GPU and run solely on Iris Pro (for battery savings). Then again, I'm on Mavericks so everything is buttery smooth on either GPU. Oddly, HDMI mirroring requires I let it switch to the Nvidia even though it works just fine on models that only have Iris Pro...

Funny. My 3 years old original 15 Retina Macbook Pro is still waiting for a miracle update that will finally make it work like it's supposed to. It's still laggy, safari falls apart all the time, using scaled resolution makes it really unresponsive and many apps are just way too slow. Lightroom on Yosemite vs Lightroom on Windows 8.1 (same computer via bootcamp) is light and day. I really can't imagine what using the new macbook is going to be like...

Paul, just the opposite here. My mid-2012 rMBP 15" runs like a dream. I don't know if that's because Apple has replaced over $4k worth of stuff, from logic board to displays, etc. but it runs just as fast as it ever did.

I do a clean install of the OS annually, or sooner if a new OS comes out. I do the USB key installer and go clean. I'm so good at that, and with the MAS I can have all my apps up and running in no time.
 
I think some people really cannot notice the lag because they are used to it.

But if you use a machine that doesn't use the scaling the rMBP's have it's a huge difference. Everything happens much faster the transitions animate quicker and smoother.

I think it's really down to a lack of GPU grunt. The 13" has no Dedicated GPU and the Iris Pro on the 15" is not good enough for these super high resolutions neither is the 750m which is a 2013 graphics card folks. It has already been replaced by the 850m and 950m by NVIDIA but Apple has not updated to either of these.
 
Can't wait to see the performance of new 2015 Macbook... Its going to be terrible if the 13 Inch MBP can't properly run a retina display.

Apple's cost cutting will come back to haunt them with the 15 inch models.
Surely they could have gotten a discrete graphics card into the 13 inch some how. Whenever I use my brother's 2014 Macbook Pro 13 inch Retina I do notice more UI lag than on my 13 inch 2012 cMBP.
 
I have a 2015 rMBP and i luckily have zero stutter at 1680x1050. Hopefully it is a simple fix with the updates down the road for others.
 
You'd expect this on the new retina MacBook with its 2011 processor. Not the 2015 MacBook Pro. Broadwell was supposed to make your battery last longer, not make your computer slower. Very surprising and unexpected.
 
You think you've got lag?

You think you've got lag? You should try my 2007 20" iMac! I'd update to something more modern if I could afford to.

I feel sorry for those who've paid good money for a 2015 MacBook Pro. On the other hand, I have to say that my iMac works much better under Yosemite than Mavericks.

"We gave them a state of the art display, without the proper video card and software to make it work properly." :)
 
Graphics performance much better if you completely disable scaling with Display Menu. Is it just me? Seems smoother, and AssaultCube (a first person shooter game) runs at a MUCH higher FPS, not that it doesn't run super fast anyway. But of course, everything is tiny as a result.

MacPro1,1? I see you've been living on the edge with your hacking ;)
Mavericks has been a disaster on any machine I've tried it on. What a worthless "update". Literally ML but much slower.

My late 2013 13" is staying on Mavericks precisely because of posts like this. Yosemite seems like Apple's buggiest release in a long time.

I just upgraded a MacBook Pro and iMac (elderly hardware) of my family over the week-end - from Snow Leopard... to Mavericks!

I'm just fed up will all those .1, .2, .3, .4 version problems. 10.9.5 comes reasonably close in stability to Snow Leopard. In a loong time (and yes, myself I went through 10.7 and 10.8, too).

And guess what: I still manage to trash my Wi-Fi connection! I can "reliably" bring it to a grinding halt when doing an iPad restore via iTunes: all the iPad backup data is located on a NAS and accessible via Wi-Fi only. During the restore (and also large iPhone backup tasks) the Wi-Fi signal strength is still top, but connection completely dies. I have to stop and re-start Wi-Fi in order to get things going.

Running a Time Machine backup (again via Wi-Fi, backup destination is the NAS) also can be quite shaky, especially when huge data (in the order of several GB) is being generated by e.g. Final Cut Pro X.
