    Hi! I have updated my project from 2020.3 to 2022.2.0b11. I work on a Quest 2. Before I had a solid 90 FPS and after updating I have a framerate of around 65-70FPS. I have compared profilers results from both versions, and for whatever reason the "EarlyUpdate.XRUpdate" call has increased its cost of 3ms to around 6-8ms consistently. Does anybody by chance know why this is the case? (I have deep profile turned on but it doesn't tell me what this call does). I compile the project always with IL2CPP on Master mode. And I use DOTS, which I updated from 0.51 to 1.0. I use Vulkan and use nearly all Vulkan optimizations provided in the project settings.

    Before updating:

    A couple of questions:
    1. Are you using URP?
    2. Just clarifying, you're using the Oculus provider, and not OpenXR? And if so, what versions are you using?
