[ODE] Simulations running in real time?

The reason your simulation jitters when changing the step time is twofold:

1) ODE uses a first-order integrator

2) if something is resting on something else, different timesteps will 
   make it fall differently deeply into that surface, leading to different 
   correction forces, and thus different exit velocities, so it won't 
   settle at steady state.

Subject: [ODE] Simulations running in real time?


Hello there I'm trying to get my simulation to run in real time, 

Basically the problem I'm having at the moment is that the simulation is running at different speeds on different computers. I'm working in C++ and using the drawStuff interface.

I'm also noticing that by changing the dWorldStep value the motion varies quite considerably, whereas I'd expected to run simply faster or slower ?

Thanks for any advice 

Chris
