I created an app for Hololens 2 using Unreal and following all steps of the chess tutorial instructions (https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unreal/tutorials/unreal-uxt-ch1). It sounds like 60 FPS should be possible and is ideal for apps on Hololens 2 (https://learn.microsoft.com/en-us/windows/mixed-reality/develop/platform-capabilities-and-apis/hologram-stability). However, the app is consistently running at 15 FPS, according to both Unreal's stat fps command and the Hololens framerate counter display. The same is true in all apps I have created in Unreal. The framerate is 60 FPS for the main menu and when running non-Unreal apps such as Tips.

How do you get the tutorial Unreal app to run at 60 FPS on Hololens 2?

    Hello, Welcome to Microsoft Q&A,

    Have you built the application with the non-debug mode? Using debug mode to build the application will increase the burden of the program and slow down the efficiency of the operation. For your case, you can consider building the project as the shipping version to achieve the best performance. Besides, to optimize the performance of programs, we would also suggest you use the real device to test the program instead with using the editor remote streaming.
