Flash CC - Rotation on movieclip containing bitmap causes dramatical framerate drop

I have a 850x850 bitmap inside a movieclip which must constantly rotate like a big wheel. When compiling for iOS the framerate drops from 24 to 8.
Is there a way to increase performance without using cacheAsBitmapMatrix and without rotating the bitmap inside the movieclip but the whole movieclip itself?

The Best Answer


You will get better performance if you make a texture atlas that contains the bitmap prerendered with every possible angle and use Starling.

But it comes with the cost of enlarging the filesize. Could be a soultion if your app targets a Kiosk or strictly local machine. Not so much if you publish for Itunes, I´m afraid.
