iOS11 - performance drop

September 19, 2017 - 11:16am #1

Hey guys,

I have a Unity app for iOS. It has simple GUI and scans object button. When a user presses this button camera enables & Vuforia starts scanning for a marker.

On iOS10 switch from GUI to Scanning happened within 1 second. (Tested on iPhone 5, iPhone SE, iPhone 7). On iOS 11 the switching between from GUI to Scanning takes 10 seconds (tested it on iPhone SE). 

 

Any ideas why so sudden drop in performance?

It does not occur on Unity 5.6.5p4.

So I think it was fixed.

I'm same issue.

my situation is as follows.

<Unity>

  5.6.2p4

  5.6.3f1

  5.6.3p4

  5.6.5f1

<Vuforia>

  6.2.10

<Graphics API>

  Metal

<Mobile>

  iPhone6 iOS 10.3.3

  iPhone7 iOS 11.2.5 Beta6

  iPhoneX iOS 11.2.1

[Result]

  iPhone6 : OK

  iPhone7 : NG

  iPhoneX : NG

 

I need to satisfy the following conditions, I hope to solve this issue.

  • I use must ARKit, that is to say, I use must Unity 5.6.2 or more
  • I have pro lisence of Unity 5 so, I want use Unity 5.6.2〜5.6.5

Is there a solution for this issue?

Or Is there plan to investigate and respond?

best regards.

Which problem?  The iOS 11 performance issues or the bug where the AR Camera is active in scenes it doesn't exist in?

I downloaded the Unity Beta with Vuforia built in.   I put two scenes in there.  One that is just a simple menu and one is the arcamera scene with my models and targets.  I can confirm that it does load faster with iOS 11 but for some reason Vuforia is active on both menus despite not having an arcamera on the menu screen.  Is there some kind of setting that only enables it on the actual scene that its supposed to be on?

For me this is happening in the apps we already have live in the Apple Appstore.  Significant difference in load times between the devices I have still on the previous OS and those with iOS 11.  I wasn't aware that the new Unity with Vuforia incorporated was already available.  I can definitely download this and give it a test.

Do you see this in the sample apps or in your own app? Also, would you be able to try this in Vuforia 6.5 which is included with Unity 2017.2.0b11?

Thanks,

I am also seeing performance issues with iOS 11.  Takes a lot longer to load the scene with the AR Camera and when returning from suspend it crashes or gets stuck on my loading screen.

 

I'm using an iPhone 6s Plus.  Vuforia 6-2-10.  Unity 5.6.1f1
