It's all the above.  Also, the more text you tween, the more important that

you choose a font whose shapes are simple (e.g., arial will tween more

smoothly than Times because it lacks the serifs).  Alpha and gradient fills

take a big processor hit. I'm not sure of this, but I would guess

complexity of the background would factor in -- even though it's not

tweening, it still must be redrawn after each frame (can anyone else verify

this?).  Remember that what is needed is the illusion of movement --

sometimes the tweens can be simpler than the start and finish images and

the effect will be the same only smoother.


Remember to set quality=high in your HTML codes (object and embed) if you

don't want "the jagglies."
