Question [Oculus] FPS drops as soos as the headset is worn

Hi guys,
I'm reposting an old issue I am still having problem with and NO idea how to slove this :/

[QUEST2]
[UNITY 2020]
[URP]

I have a scene in which nothing is happening, the FPS is something like 160 FPS. As soons as I wear the Oculus headset the FPS drop to 45 FPS. Nothing has changed in the scene, no events have been triggered, no animations have been played, nothing. Just wearing the Oculus headset make the FPS drop.

have no idea why it is happening. Do you ?

*The screenshot is from the scene with few betches and verts,
**The profiler is running on the Quest build and not on the playmode on the pc

Thanks
