hmm, the last time i had CPU-problems with [fiddle~] was on my P-100.
which hardware are you using?

you can create the [gemwin] with an argument which denotes the 
framerate; you can send a [frame $1( message to the [gemwin] to change 
the frame rate at runtime; you can turn on/off entire gem-chains by 
sending 1/0 to the initiating [gemhead]; you can use [spigot] to disable 
parts of the gemchain.

and you could use smaller frame sizes and greyscale images to reduce the 
amount of data from the webcams.
