    Hi,

    we are working on a game for the HTC Vive and using OpenVR in our project. The VRStats.gpuTimeLastFrame float is always zero. We are using the Vive at the PC and can play with it which means that OpenVR is working fine.

    Does anybody else have this problem or is it our fault?

    I will try this with older beta versions of the Unity beta today.

    Edit: It doesn't work with beta 23 either.

    Edit2: Creating a new project didn't help. The value is always 0.

    Greetings

    Tim

    No, only the OpenVR SDK should set this value at the moment. The Lab Renderer from Valve in the asset store is using this value. I think they asked unity to implement this in the engine.

    Edit: Just to be clear. It worked a few beta versions ago and is not working at least since beta 23 for us.

    I can confirm that only OpenVR SDK sets this value right now. It will come to Oculus SDK in the future.

    It worked here with OpenVR SDK on latest 5.4 build. I tried with both the released version of SteamVR and the SteamVR beta version, both are functional.

    FYI, we get this value from here: https://github.com/ValveSoftware/openvr/blob/master/headers/openvr.h#L1936

    I tested it in a build. The value is set in the build, but not in the editor. Is this by design or a bug? Because a few beta versions ago the value was also set in the editor and not just in the build only.

    I actually only tried in Editor yesterday, so I can confirm it was working in Editor on 5.4.0f2 on my machine. I'll have QA take a look.

    We were able to reproduce and we have a thread open with Valve about this issue. Will post here when we have a resolution.
