What Does Your Framerate Really Mean?

Flash FramerateWell...Tinic Uro tells us that it may not mean quite what you think. In fact, depending on your browser and your platform, things can sway -10 to +5 frames/sec from your selected framerate. That means from the Flash 8 default of 15 fps, your movie could be running anywhere from 5 to 20 fps. Tinic gives the technical reasons for this fluctuation. Most of it seems to be throttles built in by browser makers to keep CPU cycles manageable. It makes sense, especially when considering, as Tinic points out, online advertising. But its still frustrating nonetheless when synchronization is important. Like most else with the web, user experience is not always as predictable as we'd like, but at least knowing the problems will help with finding the answers.
