15 fps is _always_ going to look a little jumpy.

Also, you may have so much going on that the processor is getting chewed up and displaying even less than 15fps. Using gradients or alpha channels is a great way to chew up the processor. I'd bet a beer that you are using one or the other or both in your presentation.

Also for further reference: 12 fps is the _minimum_ to fake motion and feel smooth. Most professional TV animations come through between 12 and 15 fps (they "shoot on twos"... 24fps film and 30fps video).

_Critical_ tool for testing CPU performance is Colin Moock's speedometer. Go to www.moock.org and dig around for it. It rocks. It will let you know what you're realllllly getting and you can use that info to see if your changes are helping. Sorry I don't have the deep URL.

That's the best I can offer without seeing the piece (and probably the best even after seeing it, except I'd say: use less gradients and alpha channel stuff).

Good luck, g
