I have a very simple 790x300, 70 frame animation at 30fps. No bitmap images, just vector and text - I have animated some of the text without converting to a symbol. The final swf is 33kb, but the thing plays back slow. Plays fine on the timeline, but as soon as I export the swf it doesn't play as smoothly. I've always noticed this about Flash, but always thought it might be because I was using over-sized bitmaps or overly complex animations. So, I'm confused as to why this might be happening.
