Isn't it possible to just measure the framerate and it if consistently (over a minute or so) drops below a certain value (say 20) it turns the feature off automatically? If the framerate goes backup for a sufficient time, turn the feature back on.
IMHO this is a much neater way of dealing with the problem.
