      Hi,

      I have a scene composed of a few entities with complex geometry. This scene is never changing, only the camera is moving, but multiple CPU cores are constantly running at 100%. This happens more or less on all Qt3D examples with increasing scene complexity. I would assume that in a static scene almost all of the work should be done by the GPU and not the CPU. What is happening there? Is there any way to reduce the CPU load?

      I'm using Qt 5.9.3 mostly on Windows, getting the same results on different graphics cards.

      Thanks for any suggestions.
