Quest 2 performance question

Questions
1

Hi,
I have created a playground to stress test my Quest 2 here: https://playground.babylonjs.com/#9K3MRA#809

It creates a number of dense spheres with pbr materials, and as expected the performance in the Quest 2 is very low.

While I can see from the google dev tools that the gap between actually rendering frames is large, I cannot see the exact reason:

From the data it looks like both the GPU and CPU usage is very low and there isn’t much indication of why the frame time is low.
If I had to guess, I would suggest the GPU it taking much longer than is shown in the data.

Is there any way I can confirm this? Am I using the Chrome performance debugger wrong in this context?

Here is the actual performance data from chrome’s remote debugger if anyone can help:

Sorry! missed that and just came back from some time off.

The best way to check this issue is using the OVR metrics tool - OVR Metrics Tool Stats Definition Guide: Unity | Oculus Developers which will show you in real time what takes so long

It does seem like a GPU issue. Tested the scene in my quest (1), the CPU usage was roughly 14%, but GPU was at 90+% (and FPS was ca. 15)
