iOS 8.1 b2 iPhone 6+ no more lag!

and that the solution would be to disable some of the core features of the OS.

Haha so blur is a core feature now? Ok.

btw, the lag is not caused by the blur algorithm (that algorithm is just a trick that blurs the entire image, and not a true live blur of the view), but the scaling that is done specifically on the 6+

You're wrong. Every Apple is blurring things into oblivion, it is a live blur. If you don't believe me, go into a messages thread and scroll up or down. In the field where you see the persons name, you can see green or blue messages getting blurred in real time.

Why doesn't this cause lag? Because it isn't having to blur very much. On the "rotate spotlight search" trick, its rearranging apps, their text/name, blur it all, resize the keyboard, and blur everything behind the keyboard. A lot more resource intensive.

You must not know much about scaling done on a GPU. It is extremely light on the system. If the screen was a native 2208 X 1242, all the lag present now would be there too.

If you think scaling is the problem, you are severely misunderstanding.

----------

One should not have to fiddle with settings to see what works and what does'nt

That is opposite of Apple's mantra "It just works"

So you've never gone into the settings to make an adjustment to better suit your preferences? Ok cool.

The fact remains, going into settings allows you to adjust the system to better fit what you want. You want useless blur? You can have it. You don't want useless blur and would rather have better performance? You can have it.

I'm not trying to make excuses for Apple. I hate lag when I see it. I just recognize that there are ways to minimize lag.

lag is still there, the test of bringing spotlight while in portrait, then rotating to landscape still shows a significant lag

Correct. There's zero difference in performance on the 6 Plus between iOS 8.0, 8.0.2 and 8.1 b1 or b2. All the lag present at launch is still there.

Yes it is a core feature of iOS 7. iOS7 largest change was the UI design, and within UI design the largest change was the use of blur to bring context to various screens.

You're wrong.

Nope I am not. I am a full time iOS developer, and I can tell you that besides some UI elements such as navigation bars and toolbars (like the one you mention for Messages, and that only applies on a small portion of the screen), the other blur effects are combination of screenshot taking and blurring the screenshot. That technique is used precisely not to use an expensive live blur algorithm on large portions of the screen.

You must not know much about scaling done on a GPU. It is extremely light on the system.

It's only reasonably light if well implemented... I agree that if everything works as it should, it should certainly not slow down a simple animation such as Spotlight rotation; but that's precisely what we're saying here, the scaling thing is not as optimized as it could right now

So you've never gone into the settings to make an adjustment to better suit your preferences? Ok cool.

of course I do, what we're saying is that we don't wish to disable a feature that is:
- core to the OS
- was (and still is on older iPhones) working just fine. This phone is an upgrade, I didn't spend all that money, now to have to disable everything for the phone to work ok. This phone is marketed as twice as fast as the previous generation, so that's the expectation...

I'm not trying to make excuses for Apple. I hate lag when I see it. I just recognize that there are ways to minimize lag.

Well what you're saying is that since you don't care about this specific issue, anybody that does is unreasonable. Now if you care about the music player (I don't), and the iPhone would not play music correctly anymore, you might complain about it, and I would tell you to just not use the useless music portion of the phone...
Selfishness has its limit, if people tell you it's a problem for them, then it is... if you don't care, move on to another post, no need to be dismissive about our issues..

I don't know whats worse. The fact that Apple thinks blur is a core feature, or the fact that you do.

Nope I am not.

Yes you are. Blur is still happening behind the scenes in real time when invoking spotlight. Same thing in Safari and every app that invokes its blur.

It's only reasonably light if well implemented... I agree that if everything works as it should, it should certainly not slow down a simple animation such as Spotlight rotation; but that's precisely what we're saying here, the scaling thing is not as optimized as it could right now

Again, it is not the scaling causing the issue. Its the blur.

----------

If you are basing your entire argument off of "it is scaling causing the issue and scaling only. Blur has no affect", let me prove you wrong right now.

Essentially we have 3 main problem areas: blur, scaling, and resolution the GPU is rendering at.

Without changing anything, pull up spotlight. Rotate screen. Notice lag.
2208 X 1242 SCALING to 1920 X 1080 + Blur ON = obvious lag

Now turn on reduce transparency, pull up spotlight, rotate screen. No lag.
2208 X 1242 SCALING to 1920 X 1080 + Blur OFF = no lag

Now, how can we test it with blur on and scaling off, just to be sure? Essentially we can't. Now, is there a way to test it with a lower resolution and have it scale UP instead of down. If the problem is gone, it tells us the resolution is a big factor and scaling isn't. If the problem persists, we will know it is scaling causing the problem and not the resolution the GPU is rendering at. To do this, we change the iPhone 6+ display view from "Standard" to "Zoom". What this does is render everything at 1334 X 750 (iPhone 6 resolution) and scale up to 1920 X 1080. So if scaling isn't an issue, we will get the performance of the iPhone 6, if scaling is the issue, we will still see lag even with blur on.

So, change display view to "Zoom", pull up spotlight, rotate screen. No lag.
1334 X 750 SCALING to 1920 X 1080 + Blur ON = no lag

So in addition to the standard scenario, we have 2 test scenarios which both show obvious improvement. One turns off blur and keeps scaling, the other reduces resolution and keeps scaling.

Its obvious to me that scaling has little to no affect. Blur has a noticeable affect. Resolution the GPU is rendering at has a noticeable affect.

Can we run iOS at 1920 X 1080 native to know for sure? No. But with the display in "Zoom", we get the same performance as the iPhone 6. Meaning scaling likely isn't the issue. Blur and resolution are.

Oh! Sure! Typical Apple fanboi. Here's proof of Smoothgate right in front of your eyes and all you do is deny deny deny. Typical!

So if a phone works fine for someone with no problems and reports it they are fan boys hahaha

 

[cornerexit]

Let's hope this new release fixes the BT issues. I'm tired of it in the car, ****ing sick of it actually. I've deleted the phone from the nav, deleted it from the phone (Fresh pairing) to no avail. My 5 never did this and I'm convinced it's an 8.+ deal. My ATV's are doing the same when using the radio app. 10 minutes into playing "an error occurred" etc. Crappy software thus far.

 

[KingRVAlien]

However there are voice quality issues on calls, other end users are stating they hear static and fading while km speaking with them

Pssssst.

Humor.

My iPhone hasn't worked correctly with my Pioneer head unit via BT in my car since the 4S. Don't count on a fix.

Smoothgate!!!

Hope it's true!

So is there still lag in 6 plus with 8.1 beta 2?

 

[EJ8]

lol. I rotate on purpose pretty much never with the exception of viewing video or a photo. I also never use spotlight. I don't care if useless animations stutter for half a second either. I just want the basics to work reliably. I feel like iOS 8 on my 6 plus does that just fine. This forum is full of hyper sensitive people that complain about every little thing. They need to get over it.

This. ^

Bunch of never satisfied whining babies around here.

Apparently other than the OP saying it is gone, everyone else here is saying that it is still there.

What do you think online forums are for? Definitely not to be nice, chat, or ask constructive questions!

 

[questionmark32]

Youtube App still not fully compatible with 6+
