    Please fix this, we see 10ms for XR update in a blank scene

    This is a show stopping bug for us. We cannot get over the 90fps requirement on Oculus with this bug in place. Is there a way we prioritize this higher?

    Two thirds of the budget goes away because of this issue.

    This is the most upvoted active bug in the XR issue tracker. Any updates or discretion from those who can prioritize correcting bugs to address this immediately would be highly appreciated.

    Let me not mince words here: Please note that this single bug's severity is platform breaking -- not game breaking -- every game breaking. This bug's effects for Oculus are akin to covid-19's effects on the world economy. It has basically made it impossible to 1) publish any title for Oculus using Unity 2019.4+ (per their fps requirements), and 2) made every ever game which does support Oculus literally physically sickening for it's entire player and developers base.

    This is a big issues but seem to get ignored. We can not release any game in Oculus store because of this.(They have fps requirement)
