On the topic of arduino controllers--I recently listened to a presentation at the Kansas City Open Hardware Group meeting about Motate. It's an arduino library (and someday a board). https://github.com/giseburt/Motate
The author was motivated to write the library for motor control, but it's still applicable to bit-banging in general. He said that his code could reduce the number of clock cycles it takes to toggle an I/O (paraphrased). I haven't dived in too deep, or figured out a test for it--but I thought I'd bring it up, regarding the difficulty with higher fps rates.
