    OpenXR suddenly drops to 37fps cap after no changes (builds Quest2 store upload). It holds steady 37fps (50% performance dip) after a re-build. We are kinda stuck on this now (for almost 2 days).
    Have anyone expierienced this? Anyone knows a fix for it?

    Check the profiler and ovr metrics.
    Then see where the issue lies (ignore the 40% wait, since this probably is vsync)

    Yea we checked it, GPU Time boosts up to 30000 when building with our "build PC" and normal with random dev pc (identical projects).

    Tried with a empty scene with just only a cube + baked light + vr rig. 37fps cap and GPU time around 25k

    Is this only Quest? Which render pipeline? Can you post screenshots of your XR, RP and (relevant) Player settings? Are you doing anything in code to modify fixedDeltaTime, MSAA level, graphic settings, etc?

    Sorry for late respons.. we found out 3D Artist clicked in Decal support for some tests. It totally breaks perfomance. So Decal support off in quality scriptable.
