The difference between LAG & STUTTER and why it matters!

[vertsix]

I downgraded from 9.0 two months ago to 8.4.1 because it ran atrociously bad and I was running 8.4.1 up until yesterday.

I updated my 5s (main device) to 9.1 today, and I'm surprised. The performance issues exist, but I've gotten to the point of not caring anymore. They're not as bad as they were on 9.0. I can still do everything I need to relatively fast.

However, it would be a plus if Apple fixes them, of course.

What's the point of metal if they need to release more powerful hardware to run the same effects that the old hardware could handle? Oh, that's right, they need to give you a reason to upgrade.

I wonder if it is a driver problem. OpenGL (ES) drivers are pretty mature, even if there are lots of drawcall overhead. Maybe Apple has to step up their game with the drivers for the older devices, but doesn't see the ROI in doing so.

For the same reason him (and many others) have been telling you performances are ok for like 1000 times and you still don't accept it

People complain because they have a reason. Denying their observations makers zero sense. If you don't notice lag, just leave these threads instead of just denying it.

If it was just legacy devices. While maybe not as affected, 6S/6S+/iPad Pro are also affected. Agree they won't rewrite unless no other option - not in Apple mindset. Still, with the power that is in these devices it totally befuddles me why they are having so much issue with these basic functions.

Someone here posted once that the issues are a direct result of Metal being designed to use the resources in such a way so as to minimize the hit on the battery as much as possible. Dunno how much credence this contains but it does make some good sense!

Could be. Still, if this was the case you would expect that the issue would be far more prevalent on the 6S instead of the 6S+ (as many reviews and posters report). Either way it is a befuddling aspect of iOS9.

Makes one wonder when someone tells you that what you believe is wrong because they believe different. Empirical evidence I'll take . A number of poster's here seem to lack that aspect in their "claims".

Sounds like a possibility. Though I read that Metal makes a lot of things manual (that were automatic). Not sure how that helps battery life.

What are the chances of Apple going over to Vulkan when it's done?

Based on past history I would be surprised if Apple did. Sad as it looks like a much better alternative to Metal and a better solution for the CPU/GPU design direction. Still I suspect it is a better Android / Windows / Linux / OSX fit than iOS.

Metal is worthless.It cant even match OpenGL speed yet alone exceed it.Even on my MBA the animations have become stuttery ever since they incorporated Metal there too.Funnily enough Windows 10 on my MBA has smoother animations than on OSX

 

[Radon87000]

I think his annoyance is that the Nexus 7 isn't the iPad Air 2 in terms of hardware specs, yet the OS experience (from his perspective) is better on the N7 than on the Air 2.

I wouldnt say that.Nexus 7 2013 does have animation stutters ever since I bought it but unlike on iOS they are not confined to the same spots.For instance,there is widgets animation stutter on my Nexus 7 but if I use it a couple of seconds later its no longer there.However 3 updates later,I will say the Nexus 7 2013 performance remained consistent over time.It didnt slow down nor did it get appreciably faster. But in iOS that same lag recurs on the same spots over and over and each upcoming upgrade slows the device down.iOS no longer holds the supremacy of smoothness over Android at this point

Yup, basically similar to how it was for many in the early days of iOS 7 and 8 as well.

Completely agree on this point! iOS feels like old Android now. While Android 6.0 feels like old iOS in smoothness.
I never thought that someday it would happen, but it did and Android is the more fluid and smooth OS now.

Apple needs something like Project Butter for iOS where Google focused SOLELY on improving performance in 4.1 and removing the lag and they succeeded to be on par with/exceed iOS at this point

I feel like Apple's software quality nosedived really hard. Judging by iOS 9 stutters, multiple bugs and most of other Apple's software.

1. Stuttering still hasn't been fixed in 9.2.
2. Also Apple Music is a buggy mess, many of my songs got deleted after I enabled Apple Music in iTunes.
3. iCloud Photo Library is a slow buggy mess.
4. iCloud Mail is a mess, it delays most of my messages by 5-10 minutes.
5. It took Apple 2 months to fix bugs that made Office 2016 crash constantly.
6. Disk Utility in El Capitan is a total mess.
7. Mail app in OS X is a mess, I still don't reliable get many of my messages.
8. Apple Maps is still a joke, last night it told me that I have arrived at my destination in the middle of the interstate highway

Have Apple released any piece of software that's not a buggy mess recently?

Apparently by Apple's claims, Metal was the "Project Butter" for iOS, but it accomplished exactly the opposite.

Slight animation stutters aside, iOS 9 has been a much more stable and less buggy release compared to iOS 8 or 7 releases.

Point of comparison, Optimus technology by nvidia where GPU performance is reduced when running on battery resulting in low fps in games.
In the case of iOS 9, the coding seems somewhat botchy resulting in poor system animations where it's overly efficient.
In nutshell, clearly battery life has been given the upper hand over smooth animations. Apple really needs to get into the high gear as its attention to detail is clearly wavering.

Slight?Try sharing photos via WhatsApp or iMessage and while its uploading rotate your iPhone into landscape.The lag is so bad it will ruin your day

I've found that it isn't any less buggy than those releases:

And you say iOS 7 and 8 have been buggy as if that justifies anything. iOS 7 sucked hard and it was defended with the excuse of "Oh, it's full of big UI changes so you need to give them time to fix it up!"

I gave them time to fix it up. It's been 2 whole years and the UI is barely less buggy than 7.0.

My iPad Air 2 doesn't lag, but i see stutter all the time with system animations.

Which were exactly 0(ZERO) on 8.4.1

I never used it on iOS 8.4.1 so I can't comment.

Regardless, the enhancements made with multitasking were worth it to me. Now, on my iPhone I've gained no real benefit and slowed down the fluidity of the device, so I regret leaving iOS 8 there

I had a feeling someone was going to take it somewhere else--please see the context of my reply. It had nothing to do with justifying anything nor did it say anything about justifying or apologizing or anything else people seem to constantly try to say about what I say when I say nothing of the sort.

And it's sure is less buggy. There are practically always obscure glitches and bugs here and there, but when things just crash left and right or the phone just restarts randomly more than just even sometimes or something is just not working correctly during normal typical use of most users, that's certainly more buggy than various unusual bugs here and there that don't come up in normal use most of the time.

Yes for the most part they are slight. In places where they are more obvious it's usually something that most people won't be doing in their normal use. It doesn't change that they might be there, but does affect how much of an issue those things are. And animation stutter when o twirl my phone while some app is updating is certainly not going to cause me (and most others) to have a bad day or anything even close to it at all.

I want to agree .. well half of me does. Some aspects are more stable while others are .. iCrap
