[ODE] dWorldStep at 60 FPS

[Pierrre-Laurent CHAMBERT]

Hi Jeff

 From what I understand, your problem is the time step you use : if you 
use 0.01s at each step, and do that 60 time per second, then you update 
the physics by 0.6s for 1s of game...
if you want 60fps, you need to have time step = 1/60 ~= 0.0166667s

I hope this will help you ;)
