    Hi community, I'm trying to get my Unity Quest 2 application (standalone) updating the headset refresh rate to the maximum available

    Problem: Updating to any refresh rate higher than the default 72 causes the physics to start stuttering. When I grab an object with a rigidbody and start moving my hand I see it jittering/choppy movement

    What I've tried: OBS shows the in game FPS is meeting the cap 72/90/120, and everything else except physics based movement is buttery smooth. My understanding is that physics has it's own timestep value `Time.fixedDeltaTime`. I tried updating that in my refresh rate code below:



    Additional info:

    My time settings



    Unity Version 2021.3.12f1
    URP

    Any help is much appreciated, thanks

    Why did you multiply by 10? Just needs to be 1 / hmd refresh.
