What is accelerated compositing?

  • Mapping certain elements on the page into bitmaps
  • Maintaining painting order
  • Moving/transforming those bitmaps
  • Mapping to hardware

How is this different from hardware-accelerated drawing?

  • It's based on bitmaps, not acceleration of all drawing commands (c.f. IE9's drawing)

How is it implemented?

  • Via GraphicsLayer
  • Relies in platform 3D/GPU framework
