Looks like a plane with a bitmap already takes a lot of juice from the GPU.
Then when we had updateTexture() performance just drop drasticly.
Anyone have advice or best practice?

private var _rect : Rectangle = _rect = new Rectangle(0, 0, 9, 9);
private function onMouseMove(event : MouseEvent3D) : void
{
_rect.x = event.uv.x * bitmapWidth - 4;
_rect.y = event.uv.y * bitmapWidth - 4;
_mat.bitmapData.fillRect(_rect, 0x00fff0);
_mat.updateTexture();
}
private function handleEnterFrame(ev : Event) : void
{
_view.render();
}
