One feature that I've noticed is that the flash player will respect any commands from the browser to throttle the marshal like when its notified that its in a different tab or below the fold on a scrolling page.

Now, I am wondering why on Mac Safari Flash Fullscreen Mode, I do get a constant FPS (this only happens when in Fullscreen with Safari), which equals the one defined at compile time (side note: everything is smooth). As soon as I exit Fullscreen Mode, I do get different FPS given the complexity of is displayed (the elasticity principle happens here).

If you set your SWF to 0 fps and do redraws "manually", you'll gain a lot performance-wise but no timers will run... I discovered this while making a drawing program in Flash. J Great post!

Would you dare to draw any conclusions from this information? Specifically, do you think there could exist for AS3 the infamous "Magic Frame Rates"? Are there situations where Timers are more efficient than ENTER_FRAME and vice-versa? Any chance we'll ever know exactly how things might perform on different systems? Hey Sean,

Nice work. This is really insightful.

Gives great insight on the internal processes of AVM2. Sean, do you have a contact form somewhere? Is there any way to contact you? I'm conducting research at Georgia Tech with the college of computing and would really like to get in touch with you. Excellent article! Gives great insight on the internal processes of AVM2.

Do you know anything about how webcam video interacts with all this? I'm drawing a Video() w/ camera attached behind my other Sprites. Under some system load, the video framerate will be crippled (~4fps) while my ENTER_FRAME events continue firing merrily at ~35fps. It seems like flash is throttling its video feed, but I don't really know. For my application, it's fine if it uses lots of cpu, but I haven't figured out how to tell it that. Any ideas?
