I just read https://developer.oculus.com/distribute/latest/concepts/vrc-pc-performance-3/, it says that it's acceptable if I have a loading screen. Now I use OVROverlay to make loading screen, but will the VRC validator know that there is an overlay when it's loading? The VRC validator still reports the fps test failed even I use the overlay, so I wonder who can decide if the loading overlay is acceptable when the fps is low?
