am i reading this right? looking at the last line (49 objects), for ODE

only: quickstep from the 19th: 5.14ms 1.83ms 1.24ms 0.86ms 1.15ms
0.77ms 
0.59ms sse quickstep: 5.10ms 2.79ms 1.78ms 1.15ms 1.58ms 0.99ms 0.71ms 
now, i'm assuming that these numbers are "time to compute physics per 
frame". so the SSE version is actually slower in most cases?


Yep. You are reading it correct. From my understanding (and I don't
know 
what I am talking about here) is that SSE is mostly marketing crap and 
"can" be a lot faster in "some" cases, but generally it takes a whole 
lot of work to get any gains.
