Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

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.
