2018 15" MBP UI Lag

[kramjam]

Apologies if this has been discussed anywhere, I wasn't able to find any insights on UI performance on the new MacBook Pro. I'm trying out a 15" MBP myself, and found that even while plugged into power, animations such as opening a new tab in Safari or using mission control hiccups still occur.

Is this more of a general issue with High Sierra/macOS in general? I'm coming from a 2015 13" and figured the general UI hiccups were due to the age of the machine, but still finding the same overall drop of frames when doing simple things such as multitasking or opening tabs/windows. It's not unbearable, just hard to fathom with a $2799 high end machine.

It's normal. I've had it on every retina Macbook Pro I've owned. If you attach it to an external display without any scaling, you'll see that it runs at 60fps pretty much always. I've never been able to resize a Safari window with 60 fps for example.

2018 15" MBP here.

I didn't notice any stutter on neither mbp 13 2015 nor 2017 tb. But that's without any external displays. Do you have the stutter without external displays?

I know 15s are probably switching to internal GPU to save power, which is weaker than on 13', but if UI stutters, it should not be normal.

got mine hooked up to an external Dell 4k monitor and it's buttery smooth. Weird.

No external display use here, just using the laptop as is.

Not seeing any such lag on any Mac from the last few years. On dual screens there can be but that effects all operating systems if they don’t have some beast graphic card.

Without a video it’s impossible for us to know what you mean by lag. Every year computer users post online about lag for the last 20+ years.

Some people also have unreasonable expectations. They load up heavy websites or ten tabs and expect everything to be smooth like an empty window.
