Hi, I’m developing an app on Oculus Quest2, and have a performance issue.
before loading up my own app, the “Display Refresh Rate” and “Frame Rate” of the device showing in ODH are both 90 frame rate.

however, when launching my own app, both drops down to 72.

and the actual Frame Rate drops more during the game with more stuff on screen

my question is,
1
how to increase the “Display Refresh Rate” to 90?
2
is 72 for “Display Refresh Rate” a random number? or it was set from Unreal Engine?
any clue is very much appreciated!
thanks!

Refresh rates in VR are usually controlled by the runtime instead of directly by the game itself.

I don’t have any experience with the Quest 2, but looks like this details how to request different refresh rates:
