It works by eliminating the dependency on different browser timer implementations to deliver consistent cross-platform behavior, significantly lower CPU utilization with nonvisible SWF content, and extend battery life. Nonvisible SWFs and SWFs on hidden tabs are throttled down to 2 frames per second. Frame rates of visible SWFs, timers, and local connections are limited and aligned to the player's periodic timer. Video can play back at any frame rate, increasing video playback fidelity.

This is to say, as long as the frame rate of nonvisible SWFs(the covered SWFs by other windows) lows down to 2frm/s, the frame rate of visible SWFs will be moderated as well in order to keep a higher video playback fidelity.

The fact that most SWF converters on the market now are only with cripple support to Flash Player 10 or even earlier versions, may be a big frustration for whom want to enjoy the dynamic flash on other media devices. During the capturing and converting process, if the current window is accidently covered by others or minimized, the frame rate will drop to 2-8frm/s dramatically due to one of the new features of Flash Player 10.1 - periodic timer, which is mentioned previously and aims to maintain a relatively higher fidelity.
