The difference between LAG & STUTTER and why it matters!

[RebornProphet]

Or people who actually use their phones.

Exactly!

You and I had some exchanges in the early days of iOS 9 regarding lag/stutter but I am delighted with 9.2 so far even though it's only in beta.

On my Air 2 and iPhone 6 it's great. I cannot imagine using my iPad without Split View now, there's no way I'd go back to iOS 8.

Metal was never meant to bring better performance. Metal was meant to lock developers into iOS ecosystem to the point where it would be difficult for developers to port their apps into other platforms such as Android.
Don't believe what Apple's marketing says.

We're not talking about Metal in third party apps. This is about how Apple promised better performance in the OS because of Metal while in reality it's either worse to people who see these frame drops or it's only "fine" or "as good as iOS 8 was" to the apologists.

This is right on the iOS 9 web page:

It may say "the apps", but it also mentions that it is responsible for "the multitasking features on the iPad" so it is baked in to the SpringBoard animations, which is where the frame drops are happening.

The whole performance promise is a blatant lie. Even if you're one who tries to downplay the performance issues and say "OH, IT'S FINE FOR ME!!!!1!", you still won't find anything in iOS 9 that shows an IMPROVEMENT from iOS 8 like Apple is saying. If anyone thinks I'm wrong about that, give me a concrete example of where iOS 9 is 1.6x improved in animations.

I really don't even know why there's such disagreement over this. Do people think there are iOS 9 users making up these complaints just for fun?

On the other hand, do people who like IOS 9 better than IOS 8 for various reasons make these things up, just for fun? The biggest thing is Safari improvements in IOS 9, even if the other aspects are downplayed.

I don't think you're making it up. There are some areas, fluidity wise, that need to be addressed.

Having said that, if someone is pleased with iOS 9 and says they see no fluidity issues, that is their own unique experience. Everyone's experience is and will be very different from yours. It's obvious you're not a big picture person. You are into the finer details of iOS 9. Nothing wrong with that and that's your unique experience.

Where it gets frustrating for you and folks who want the ultimate smoothness is, you can't seem to accept the folks who say their experience is just fine with iOS 9. Impossible they can't see it! In a sense, you are frustrating yourself by not accepting that others do see things differently.

I sympathize and understand you're frustrated, but sometimes that frustration is brought upon by one's own actions. It wouldn't be worth the aggravation to me, but as I said everyone is different.

There is nothing wrong with liking iOS 9. But how is this relevant for the lag/stutter topic? Don't get me wrong, I also like certain iOS 9 aspects, like the said safari stability (and the adblockers). But everytime i use my mini2 i'm getting highly annoyed by the animation/scrolling/app start performance regression. It doesn't look like an isolated issue, which happens only on my specific device and configuration. Other seem to be also affected and the regression can be measured via Xcode. So Apple should be held responsible, especially when they advertised improvements and still deprive us of an option to downgrade.

PS: Therefore i can even tolerate some of the hyperbole around here, as long as those stubborn people continue to file bug reports and complain at Apple Support, which hopefully leads to an improved iOS for everybody.

You say that as if its hard to spot.Theres been many instances when even when scrolling the apps on homescreen after quitting certain apps there is a stutter while I scroll.If iOS 9 performs similarly or worse than iOS 8 (which it does) Apple failed at this update because performance is one of the highlights of this update.If you subtract performance you end up with the notes app,an improved Siri and stability,Some of which functions ,third party apps already gave me.iOS 8.4.1 was the pinnacle of fludiity.You keep saying Stability but it was NOT as bad as you make it sound.So should I say you were into the finer details of iOS 8.4.1 with all your stability issues with it?

This topic is being rehashed in multiple threads. My devices don't have lag or stutter on iOS 9 because:
A. I don't see it,
B. It's not there
C. Per chance it's configired in a way where there is none
D. Some, none or all of the above.

If you turn off animations and reduce transparency there is no lag
If you dont use Facebook,Tapatalk,WhatsApp,Google Apps there is no scroll stutter
You and many others refuse to accept the fact that XCode Instruments shows that iOS 9 has lower fps and high CPU utilisation in almost every scenario by saying "Good enough" when what was promised was "BETTER than iOS 8"

^^All of the above apply to you.You basically turn off Metal when you enable these options so ofc no lag

Good for you. Honestly this makes me a bit jealous. But how does this help other people with stutter/lag problem? I can only extract the information from your posts that the issue might not be widespread, but nothing else. If i apply your questionnaire in the same way, i end up with the same useless answers. My device has lag and stutter on iOS 9 because:

A. I see it,
B. It is probably there (measured via Xcode)
C. I ruled out a configuration problem with clean install and a hardware exchange
D. Some, none or all of the above.

So after filing a bug report, there isn't much left i can do. I can't downgrade. So i either sell the device with a loss or i hope for enough other complainers, so Apple eventually changes their mind and fixes it (like they did with e.g. discoveryid).

I advice that you stop hoping, there's no fix coming. If there was, it would have come in 9.2, but it didn't.

Another reason why there will be no fix is that apple has no incentive to make older devices faster, they don't make money that way.

I found an easy solution. I just bought Nexus 6P and that was the end of all my problems with lag and constant checking for new iOS updates.

Same kind of talk when it came to all kinds of issues in early iOS 7 and iOS 8 days...and now the latest versions of each one of those are seen as great examples of things working well and used as comparisons of how good things were in previous versions.

What good would a fix do, if most of the device's lifespan is spent in laggy iOS version? Yes they may release a fix sometime in May of nex year, but I won't be waiting that long. I will just sell my device and buy a nexus 6P, which I already did

Sounds like there's a solution then.

It looks like a planned obsolescence argument. I don't know about that. El Capitans animations are way faster on my 2009 cMBP and 2013 rMBP than their predecessors. Maybe their iOS team has too much on their plate this year, they launched a lot of new more or less iOS based products 6S, iPP, watch, atv4. Not really a good excuse for the company, because even some of those new products leave a lot to be desired.

The way the 6s sold, the market disagrees with you. Also since AW is outselling the competition the market disagrees there was well. To early to tell for the IPP and ATV4.

This argument is old. I don't care how many phones Apple sells. I give two hoots if it sells 5 billion devices in 1 hour. I don't follow the herd, all I care about is MY experience with device.

Majority of the market is made up of 5S which are hella laggy.People use them because they are locked into the ecosystem and they have to upgrade their iPhone for better performance.Its planned obsolescence

Certainly a nice crafted argument to back into a flawed premise.

Right. So is it your experience with the 6S AND AW AND IPP AND ATV4? Or is it a bit of an exaggeration (read: hyperbole) of a general nature with one device assuming everyone with those devices shares your point of view?

 

[scjr]

You say that as if its hard to spot

You didn't read my reply, but let me expand.

I did not say it was hard to spot. I specifically said, that areas need to be addressed. The crux of my reply addresses your specific reply. You will not change the experiences of other users, as much as you want the validation of others to validate the issues you're having. It's a circle jerk of madness you will never win.

Let it go, report your bugs and hope they are addressed. Anything else is a serious waste of time.

How is it planned obsolescence when even the iPad Pro suffers from this lag?

 

[laudern]

I honestly don't know what you guys are doing to your devices. My iPad air 2 is as smooth as butter. No lag or stutter. Everything works as it should.

#smoothasbutter

 

[Act3]

Turn on reduced transparency, use iPad Air 2 for a few hours with it on, turn it back off. You then may notice the stutter, especially when using the split keyboard.

Did you use the tablet extensively when it was on 8.4.1?

 

[bandit1976]

8.4.1 was not smoothier than 9.2 beta4!
