Pretty much all of the above, the zoom like animation when launching / opening an app especially !
Cool, thanks. I have resisted upgrading because of the repeated UI lag introduced by iOS 11. But... I want the security fix for KRACK. so it's great to hear the issues I had heard about are improved in 11.1.

I ... am so happy that I have smooth scrolling again on my iPhone 8+. The phone feels like it isn’t struggling anymore. Battery life was fine before, but I wonder if this means there will be an improvement or not, either way, I’m just happy as ever that the scrolling is now smooth.

Yes. 11.0 made my 12.9 inch iPad Pro with ProMotion feel like ProMotion was disabled. Very sluggish. Now with 11.1 I see 120 FPS now again.

iPad Pro 9.7 updated from 10.3.3 to 11.1 tonight. Performance has suffered, including a small delay when scrolling up and down web pages in Safari. Seriously Apple? I hope it gets better, since it might still be indexing. But so far I regret updating.

You missed 11.0, 11.0.1-11.0.3? That was slow. 11.1 feels closer to 10.3.3 to me, though yeah, 10.3.3 was probably the fastest best iOS I've experienced.

I really want to know how you measure fps with your eyes? Can you tell the difference between 118, 119 or 120 fps? lol

I skipped them because of reviews about performance on iPP 9.7 like mine. I did a factory restore set-up-as-new and it felt about the same. So I did another restore from a backup and am going to live with it. It's not terrible, but there seems to be a slightly lag/delay when scrolling up and down a web page which is noticeable and frustrating.

I didn't go to 11.1 GM as was running the betas and then 11.2b1 dropped. When I installed 11.2b1 on my 10.5 I instantly noticed that ProMotion looked noticeably improved and all scrolling seemed to be much smoother.

Thank god 11.2 continues the improvement ideally 11.3.x will perform smoothen then 10.3.3 on the new iPad Pro’s we want some some optimization love Apple. The A10X shouldn’t stutter tbh

Installed 11.2 public beta 1 today on iPad Pro 10.5. App Switcher is still stuttering like in 11.1.
I imagine by the full release it’ll either be solved or severely mitigated at least. Damn this stutter is so annoying like for real the iPad Air 2 doesn’t stutter like this, it’s had what 3 years of optimization’s though, hmmm hopefully the Pro’s will age like a fine wine. At least opening apps doesn’t stutter anymore that was god awful.

On my iPhone 6, going from 11 to 11.1 has slowed things down, further slowing since 10.3.3.

Scrolling is generally not so bad in Safari, but pretty bad in other apps. Opening apps is slow. Animations stutter too.

Keyboard seems to work fine for the most part.

Ah, the joys of an “old” device.

Try a soft reset then let your device sit for 15 minutes to index
