ODE doesn't care about a viewfrustum. ODE is only a physics-engine.

not really...
Only a poor idea:
You can damp the objects outside your viewfrustum more than the objects inside.
So the objects i.e behind the camera gets disabled earlier ( more performance ).
But i think this is a bad idea, the effort is bigger than the benefit.

If you have a very very big level, then you can separate the whole level into different worlds and spaces
and step the with different timesteps. The problem is the transition between the worlds:
Somtimes a body is in both worlds; and how to implement this?
