For some reason I experience a FPS drop of about 10 frames when I turn on the audio input?!

Any help avoiding this would be greatly appreciated.

you're probably going to have to systematically disable small units of processing in your patch until you can track down what is causing the FPS drop.

I haven't opened the patch, but are you possibly using a Mac Pro with a Nehalem processor? A friend recently sent me this link...

... which reveals that these machines take a 20% performance hit when accessing their audio systems. (A driver fix is reportedly in the works)
