Say I have a shape like this: ![](http://forum.kirupa.com/uploads/kirupa/5630/13769036a6892968.jpg) I have thought about some solutions: 1 - One mixed shape ![](http://forum.kirupa.com/uploads/kirupa/5631/a3844c2e012b1f7c.jpg) 2 - Two different shapes ![](http://forum.kirupa.com/uploads/kirupa/5632/9c4cc56cfdb4dcbc.jpg) 3 - Two different symbol with many layers and many instances: ![](http://forum.kirupa.com/uploads/kirupa/5633/bf6fab62687c4ab5.jpg) When I have thousands of such shapes on stage, and cannot be bitmap-cached, which one is the best for coolest CPU load? Any one tested it before?
