Scene3D Cpu load

    XMLWordPrintable

Details

    Description

      Hello,

      I use Scene3D in a simple Qml application under Windows 7 / 10

      ApplicationWindow {
          ...
          Scene3D {  anchors.fill: parent    }
      }
      

      Even with the above example, which doesn't do anything, the Cpu load is ~20% and the Gpu load ~50% even if i set the enable and visible flag to false ,or add a FrameGraph with QNoDraw.

      This happens on all computers i have testet.

      This slows down the entire program with slow tablets.

      I think thisis a Bug, or did i miss something?

      Thank you
