Flash performance for game dev: native render VS BitmapData framebuffer

Question

I develop a 2D shooter game with lots of objects and aggressive scrolling.

QUESTION: which way is better?

CHOICE 1 - use nativ

Answer 1

If you are doing hundreds or thousands of objects on a screen (such as with intense particle effects), then you will have better performance with CopyPixels.

A lot of this just depends on what you're trying to do, right?
