They should let us disable metal

[msae]

We're all interested in finding a solution, however, it isn't as simple as "A-ha! I've got it! Disable this, enable this, go very much faster!" We know reduce transparency helps, but disabling features to attain equivalent performance isn't the answer. It seems a few developers noted sub-optimal performance of the Metal API, at least in terms of the frame rate of the content.

Many people are upset that they've paid a premium price, for a premium product, and they feel let down. Honestly, as I (and many others) have said in several posts, the best option is to file bug reports and feedback with Apple. Go to bugreport.apple.com and www.apple.com/feedback/. It's worth a shot, at least.

Yes, seriously.

Please go.

There is no real difference between iOS 8 and iOS 9. Probably 99% of all iOS 9 users would agree. I don't know how you are using your iPhone but I can say you are using it wrong.

If you want to pin anything on metal, first show even a tiny amount of understanding about what metal is.

That's funny because a poll was held on 9to5mac and approximately 70% said that iOS 9 was slower than 8 and only a measly 20% said their device was the same as it was on 8

Metal is not all bad. El capitan is very smooth with my rMBP but for some reasons ios9 lag like hell with my iphone 6

i have a 6 on 9.0.2. just reset settings, and it does seem smoother. down side is i had to set up touch id from scratch again. plus i have to re-allow any location based services.

i'm attempting to be mindful of what i re-enable, however i wonder if once i get whatever i need turned back on, it'll be back to the way it was.

Did you update your phone from 8.4.1 or somewhere OTA from 9.0? Currently on 9.1 beta 4 and it's going great so far but still seeing stutter

It's a placebo effect. Resetting settings has nothing to do with fixing choppy animations

Of course that doesn't control for what device they installed it on. For me, iOS9 seems quicker on my iPhone 6. But it is slower on my iPad 3rd gen. A simplistic poll like that tells you nothing useful.

A poll in which a tiny sub-percentage of iOS users participated in most of whom are people that like to post on tech forums and thus like to nitpick things to their fullest ability. Sure, that's a good unbiased representative sample.

And yet for some it actually fixes various issues.

I definitely saw an improvement right after I did it. Unfortunately this morning it's back to being as stuttery as ever. And all it did was sit on a charger overnight.

It's amazing to me that people have such a hard time believing that others aren't having the same problems they are, or that certain fixes work for others even if it doesn't for them. No one is saying these folks aren't having issues. I firmly believe them when they say they are experiencing choppy animations or slowness. But that doesn't mean it's true across the board.

People on the extremes--some just can't accept that everyone isn't having the same exact issues and therefore must be lying or just blind, and some others on the other side can't accept that there are some people with actual issues. The rest are in the middle where reality actually exists and their experiences differ at least to some degree. But the middle and reality just not "juicy" for arguments and rhetoric, so some people like to be on the extremes for that.

Some people are less senstitive to framedrops or low framerates than others. However, I'm 100% sure that people who claim their devices are running smooth on iOS 9 aren't if I use them. There is no logical explanation that explains huge performance differences between identical phones. Every 5s and 6 I've used on iOS 9 is stuttering and choppy. Every single one.

I believe the people who claim they aren't experiencing any issues on iOS 9 regarding smoothness 100%. I'm also 100% sure that I would experience issues on the same device.

OR...

They are running smooth, just as they say they are. Stop being so arrogant to think you have some sharp eye for things that others don't. I pay attention to things like this too. I always notice it whenever I play around with an Android phone. I have devices in my house right now running iOS 9.1 beta, 9.0.2, and 8.4.1. Some are iPad 3rd gen, some are iPhone 5 and some are iPhone 6. The only device showing lag or frame dropping is my iPad 3rd gen running the iOS 9.1 beta. I can compare among devices and iOS versions and there is no difference. I did notice problems on the 2nd beta in particular, but that stuff cleared up.

All I'm saying is, quit acting like you're some savant that understands or sees things so much better than others. Accept that some devices might be having issues while others aren't. It's quite common when these updates come out for some users to experience problems while others don't.

That is the case unfortunately, some people have no ability to see the difference in frame drops. It goes back to the 30 FPS vs 60 FPS argument.

Could be that they're running smooth. I don't think so however. I've used a dozen or so different iOS 9 devices (5s/6/6+) and they all show the same choppiness. I'm entitled to my opinion and it is by no means arrogant.

And I believe you. Try and do the same courtesy for others.

 

[Merkie]

I believe other people as well, already explained that. Until I see a iOS 9 device that is perfectly smooth with my own eyes I will not change my opinion.

 

[Merkie]

In any case, this whole discussion is irrelevant. A lot of iOS devices are definitely having issues and Apple should fix that.

 

[QuarterSwede]

An easy way to see the fps difference is to enable reduce transparency in Settings > General > Accessibility > Increase Contrast. Invoke the app switcher. Then turn the switch on. Invoke the app switcher again. See the difference? One is butter smooth, the other is not.

 

[C DM]

While at the same time some people actually have bigger more widespread and noticeable issues while others only have a few framedrops occasionally in a few places.

My phone isn't showing any difference. I go back and forth, invoking the switcher, even scrolling through the cards. There's no frame dropping on my phone.

And please do not tell me I'm unable to perceive the frame drops but they are really there.

Where exactly do you see this choppiness? Except app switcher and spotlight search. Those two are the only cases where I'm experiencing slight framerate drops. Everything else is 100% smooth.

 

[Jayson A]

This is too funny. iOS 9 runs really good on my iPhone 6.

Seems like people forget quickly. This isn't even remotely close to the stuttery laggy mess we got with iOS 7.0 and 8.0.

Compare an iPhone 6 with 8.4.1 with an iPhone 6 with 9.0.2 on it and the difference in performance and responsiveness is incredible.
