Dear all
Thanks for all your help , I try my best to improve my knowledge about vector graphics basics and flash.
I will reduce the FPS at the same time.

> Sure. That is the hardest part (in terms of CPU usage) when rendering vector graphics. You have to understand that Flash is a *vector* animation format and is completely different from MPEG and similar video formats. A Flash player has to *render* the scene in real time which much depends on *what* you see in the movie.

Try also to reduce FPS. Sometime FPS is high for no apparent reason.
