[ODE] ODE behaving differently for different renderers

Did you just change the renderer to test_buggy demo, or did you recreate  
the whole thing from scratch using your renderer?
In the first case, the should be almost no differences.
In the later case, make sure you do exactly the same things, in the same  

Read the ode wiki for more info regarding how to create a reproducible  
simulation, including issues with DirectX changing cpu float/double  
precision whenever it wants (could be your problem if you use d3d instead  
of ogl), and other issues.
