I agree on that also.

D3DX is "somewhat" optimized for vector/matrix/quat functions (better:
functions on arrays of them). But whatever function is called, it's not
inlined (those that are, are just plain C code with no SIMD).

For SIMDizing ODE, it's probably better to SIMDize the chunks of critical
code on the whole, than small operations for vector math.
