If you’re still churning out Flash banners, please use this!
I created this simple utility, called SWFIdle, to enable the Flash Player to lower its CPU usage while the user is not interacting with it. Since it’s possible to have multiple Flash instances embedded in one page (for example, a game and a couple of banners), I recommend using this in your projects, so that Flash instances needn’t fight for CPU and give Flash a worse name than it has already 😉
I know there’s the hasPriority embed attribute now. But:
- That assumes you have access to the HTML that embeds your SWF
- If no other players are present, it has no effect
- There’s still usually little reason to be running your SWF at a high framerate if the user isn’t interacting with it
- Flash banners with wastefully unoptimised drawing routines are probably one of the key reasons that Flash got poo-pooed off of mobile platforms and disabled on everyone’s laptops – CPU usage = battery usage!
