I just read an description of an book, AS3 executes code 10 times faster that old versions, is that true? And There must be more reasons to use AS3, I believe.

To set things straight, if I would do something with 3DFA in AS3 I would have to use the latest version of 3DFA (3.9.8.7) and I would have to choose to export an Flashanimation in Flash 9, right?

I've tested to do something and it just got screwed up when I selected Flash 9 there but it was some simple test of old code perhaps and I don't remember more than that it did not work...
