Extension introduction Display Refresh Rate is used for dynamically adjusting the display refresh rate in order to improve the overall user experience.

Introduction In XR, the render pipeline will sample the content (what the player sees in the app) twice. By doing so, the graphics looks worse and makes it harder for the player to see some important information, such as texts. By using Composition Layer, we can bypass one of the sampling processes, which will result in a much better and clearer image.
