i've created a full spectrum color wheel Sprite object that is composed of 1440 vector triangles, or slices if you will.
since i want to animate the color wheel, i've activated the display object's cacheAsBitmap property. however, caching the vector as a bitmap does not increase performance during animation – it remains slow, jumpy.
importing a PNG screenshot of the color wheel into the library with lossless compression, converting it to a Sprite, and rotating this new image asset performs great during animation.
why does an uncompressed PNG image asset import out perform the same vector image with cacheAsBitmap property set to true?
