[ODE] Physics Engines comparisons and benchmarks

[Erwin Coumans]

ODE should be faster then Newton for average to large stacks/simulations.
Recently I've compared Bullet physics engine running in the C4 game engine, 
next to a Newton integration.
Newton was much slower, due to non-linear solver. ODE quickstep is currently 
a bit faster then Bullet's sequential impulse solver, but Bullet has better 
convex collision detection (which is not really an issue, they are both open 
source, and Bullet collision detection will be added as an option to ODE.). 
I've never seen a long term future for Ageia, and having worked on Havok and 
Bullet, I would say Havok is the best if you can/want to afford it, and open 
source (Bullet & ODE) second.

You can read a very recent discussion with the Newton main programmer Julio 
Jerez here:
