Probably because double precision floats are just as fast as single precisions if you don't vectorise. I bet you didn't.

This would also explain for instance why many programming languages drop single precision floats altogether: they don't plan to vectorize in the first place.

Yeah, it looks like ODE doesn't use SIMD or anything, and hence performs poorly compared to more modern engines: http://blog.wolfire.com/2010/03/Comparing-ODE-and-Bullet
