The decrease in speed is from the shadow updates, just like you say. SimpleShadow used without constantly calling apply() and positionPlane() to redraw the shadow should perform just the same as the BitmapMeterial method. Its once you try to leverage the shadow redrawing functionality that things slow down. But in still scenes, or scenes where the shadow does not need to be redrawn, you are absolutely right Fabrice.
