Keep or return? So much UI lag..

13" 2015 rMBP here, Core i7, 16GB ram, 512GB SSD. Cost me about $3k CAD.

Ive notice scrolling pictures is choppy, resizing windows is embarrassingly slow, and scrolling web pages is laggy. Was like this right after initial setup. Oh..and finder flickers..

My 13" Air isnt like this at all except the pictures thing...so is this something that will get fixed or is it just that the retina resolution will lag it too hard even on the iris 6100? This is kinda bad for the price..
 
I purchased a computer with the same specs and haven't noticed any issues other than resizing windows(to be honest, it doesn't matter because I don't use my rMBP to resize windows all day long).

Which browser are you using?

Chrome.

I haven't noticed an issue with safari. Try that and see if you notice lag?

I use chrome cause it Sync's with all my stuff. Even before I had chrome installed i noticed menus in sys pref etc were choppy. Even with chrome closed im seeing lag everywhere in the UI. Battery is awful to. Think ima take it back since my google searches show that Yosemite just broke the hell out of retina macs. $3k shouldnt buy me UI lag.

Like I said, I've got the same model as you and I'm not seeing an issue with the UI(aside from window resizing), and I get between 10-13 hours of battery life.
 
If your not happy I'd say take it back. Personally if I spend that much on a computer I don't want to have to compromise on anything maybe hoping for a fix.

Chrome uses much more battery than Safari.
 
Even without chrome running its painful. Settings menus are choppy when moving around, My Air is much faster than this thing for sure in terms of UI smoothness. It's barely set up too, so when all my apps are installed I imagine this thing will be completely unusable.

Well, I'm not sure what's going on then. Mine doesn't seem to have the issues you're having. It sounds like your only option may be to take it back and get a refund.
 
If it's brand new, spotlight may be indexing still. Also if you turned on FileVault - that will slow things down.

Otherwise - go into activity monitor and see what apps are hogging the CPU.

Chrome on a Mac absolutely sucks. If you didn't foreclose it, it may still be open and draining the battery. It's a known issue and is something Google needs to fix.

Did you do a clean install or backup from another computer?
 
On the technical side, the Iris graphics isn't really up to par running at 2560 smoothly. If you are using the 1440/1680 scaling, then you are obviously pushing the actual resolution to 2880/3360.

Plug the MBP to an external 1080p monitor and close the lid. Plug in a external mouse/keyboard and try all those activities again and see if animation still run as sluggish as before.
 
Same here coming from an 2013 13' Air:

On the new 13' rMBP 2015 Yosemite performance is just worse. And I doubt this will improve over time.
 
Not true

The graphics are easily powerful enough, hell crappy little arm processors run such pixel numbers on smartphones with no issue at all. It is the badly coded and optimised software in OSX causing the issues.

You are right about the software optimization. OSX relies heavily on animations for all it's nifty features. I have been switching from my 2012 15" RMBP to my 2014 RMBP using the Intel graphics, HD5000/Iris Pro. I've notice horrible and inconsistent animation from just mission control and opening my application folder in the dock with the 2012. What's worse is scaling it to 1680 or 1920, the overall system just feels sluggish from the choppy animations. The issue, however, is easily remedied by switching over to the dedicated 650M. Everything is buttery smooth, but at the cost of battery life and heat.

The Iris Pro in the 2014 is actually really smooth. It's tough to distinguish it from the dedicated 750m.

TIP: for slight improvement to your animations. In the ACCESSIBILITY Menu, in the control panel, check the "reduce transparency". I've found it did help a bit in overall smoothness.

I use Chrome on my PC, but it doesn't really play too well on OS X. That's the major reason why you're seeing the performance issues. Try Safari, though I understand you use it because it syncs but still, before you throw out the baby with the bathwater (so to speak), try other applications to see if you incur similar lagging.

Those crappy little arm processors don't render such pixel numbers because the Retina Macbooks render the image at a far higher resolution and scale it back down. And they are obviously ill equipped to do so, badly impacting overall user experience.
 
They do

The samsung galaxy S6 is running a 1440 x 2560 screen with a crappy little arm processor no issues at all. And i'm pretty sure there is some scaling going on there too.

This. Chrome is woefully inefficient. I'm rather certain that its issues that reduce battery life by 30% vs. Safari are also contributing to the UI lag you (and others) are complaining about.

If you chose this machine for its stupendous battery life, you're missing the target by using Chrome.

Amen. I am sympathetic to those who want to keep the sync features of Chrome, but Google could make Chrome work better on OS X and it is choosing against doing so, which is unfortunate.

Safari's animations are also much better for zooming and swiping back IMO.

I returned it. Chrome is flawless on my Air right now, always has been, not even a jitter...
 
My 2012 rMBP is running Yosemite just fine and I don't need to install Chrome and never liked Chrome. I like Safari better. :apple:

What about Firefox browser?

Airs don't have retina, and are generally much smoother than any retinas. Both my wife's and my own 11" air are smoother and more fluid than the retinas I've owned.

You're probably taking more of a battery hit on the air with chrome. So don't expect jitteriness - expect less battery life.
