Why is Scene3D so slow?

  • Hi,

    I am trying to integrate Scene3D in a QML app but especially when compiled for Android it is incredibly slow. On a modern device I get like 3 fps even for a simple triangle. This is also happening in the Qt Scene3D example. If the same scene in rendered in a pure Qt3D app, it is running smoothly. What is the reason for this difference? Is there a way to get Scene3D content to run with regular performance?
    I have tested this with Qt 5.9.2 and 5.10 beta with the same result.

  • Apparently the following property should be set in Scene3D:

    multisample: false

    It does not even exist in the documentation, so I can only guess what it does, but it solves the FPS issue for me.
