ARKitRemote - normally this slow (iPhone 8)

Hi all,

Compiling on Xcode10.1, to an iPhone 8 (iOS 12). Unity 2018.3.2f1.

ARKitRemote project is Marked as Development Build, and I can connect from an example scene project to the built 'remote' player on the phone.

I've selected the USB option (I've also turned off wifi, just to ensure there's no way it could be talking over that) and I still get REALLY slow (well, I suppose what I consider really slow) performance on the remote. 3fps, maybe?

Is this normal?

Here's a recording from the phone: https://www.dropbox.com/s/m31adnn1nzh8ze1/ScreenRecording_02-02-2019 13-21-31.MP4?dl=0

I profiled the remote, and it's spending 99% of its time doing il2cpp_z_deflate/deflate_slow.
As soon as it stops trying to send video, it's really fast. i.e: if you swipe down to get to screen recording on the phone, that action stops video, and the tracking and camera information as seen in unity is then liquid smooth. So... slow video frame sending it seems?

Any help appreciated. I hope I've provided enough info.

 

same behaviour here: very low fps when using AR Kit Remote - on Unity 2018 3.4f1, and Iphone 8 plus with iOS 12.1...

any help would be appreciated!!

 

Unfortunately this is "normal" behavior.

 

Yea, it's just terrible performance
