Bug 15 FPS just showing menus in Android - Gfx.PresentFrame takes 60ms [2021.3.14f1] [Samsung S9]

Hey there,

now that our iOS application is live, we were looking into an Android release.
I first thought our app is slow on Android during the AR scene, but it seems it's already slow in the main menu.

I have even tried setting

Code (CSharp):

1. Application.targetFrameRate = 45;

but that also didn't make a difference.

Main thread seems to wait for render thread in `Gfx.WaitForPresentOnGfxThread` but the render thread `Gfx.PresentFrame` always runs for 58-66ms, which feels rerally weird given that I am just showing some text and images in the main menu.

Is there a know issue about Android rendering being categorically slow?

I also ran some ARFoundation samples from https://github.com/Unity-Technologies/arfoundation-samples and that seems to run fine, so I'm a little befuddled what could be wrong in my project.

 

For comparison, this is how I expect the profile to look (running an ARFoundation sample app on the same android):

The actual work should be done in 6ms, and then it should start `WaitForTargetFPS` (in this case 30fps)

 

Turns out the problem can be replicated with the default 2021.3.14f1 URP(3D) project
(1) download URP (3D) template project
(2) create new Unity project based on (1)
(3) remove OpenGLES2 from Graphics APIS
(4) make development build for android with profiler attached
