To make 2d games with stage3d hardware acceleration ,it's best to use starling framework ,and starling tutorials do not use flash pro cs6 ,and designing levels is done in code ,so does that mean because flash pro cs6 use old Flash API ,and it does not have hardware acceleration , I mean if you convert an art on stage to a movie clip with flash pro cs6 ,does Flash editor Do it like Flash.display.MoviClip Or Starling.display.MoviClip ?
and if Flash pro cs6 use "flash.display.MovieClip", does that kill performance, or your game does not have to be all starling to get stgae3d hardware acceleration ?
