(I'm writing this w/o checking the code) IIRC multiloop tells you how often the FDM is called between drawing the results via OpenGL. This is a int and in terms of fps. What we should do, is to tell the fdm the elapsed time since the last call (the dt) in seconds (or milliseconds or days or years or whatever; seconds would be best as it's SI). This has to be a float value. This dt could get calculated by the elapsed time bewteen the last redraws divided by the multiloop. Then the FDM get's calld multiloop times.
