How does flash player handle objects when they are no longer on the visible stage? Is the graphical data still in memory? Does hittestobject/point consider them? Are enterframe and interval events still running?

In AS2 I would hold metaobjects (minimal x,y,width,height data) that would delete/create movieclips as the screen scrolled. Is this still a correct approach in AS3? If not, is there anything I **can** do to offstage display objects that improves efficiency, assuming around 400 are created initially?

Thanks! 😃
