If the dWorldStep time is 7 milliseconds, isnt ~143fps the number you should
be reporting? It might be questionable that you are doing only one worldstep
in one rendering step, but if someone wants to know how fast ODE is this is
the best way of telling them. :-) And any rendering shouldnt interfere with
these numbers of course.
