Unity seems to have no official information on how to debug high frame rate Android devices. I tried various methods and couldn’t make the frame rate of my game or even an blank project higher than 60hz on Android devices, even though it is very simple for the PC platform. This subverted my understanding of game FPS.
My device is OPPO Reno Ace which has 90hz refresh rate screen. The Unity version is 2019.4.10 LTS. When I use Screen.currentResolution.refreshRate to detect the refresh rate supported by the screen, the system returns only 60hz. But there are some games that support 90hz on my device. They can all run perfectly on my device at frame rate higher than 60hz (some of them are Unity projects).
I don’t know what is going on, please help.
