V-Sync Always Turned On

edited January 2018 in Questions And Answers

I'm trying to measure the frame rate of my HoloLens applications built in Unity, and for some reason, I can't turn v-sync off whenever I deploy to either the device or the emulator. I have tried changing it under project settings as well as adding QualitySettings.vSyncCount = 0; to the start function of various scripts. When I just run my scenes in Unity, I get frame rates around 160 -170 fps but running a release version is always 60 fps and frame time of 16.7 ms no matter what I do. Has anyone else had this problem?


  • Bump! Has anyone encountered the V-Sync issue as well?

  • Hi, I also have a problem like you
    I create UI and test them with HoloLens 1 but the frame rate drops until 15-20 FPS, So I check with profiler in Unity to see a graph. They are 2 things interesting that are Vsync and Rendering. Next, I try to turn off Vsync in Unity to see a result again in profiler but they still have Vsync happening while I am testing my app. I don't know what is wrong? even my UI is simple and cannot make FPS drop.
