[ODE] ODE running very slow on Windows XP 64bit

What dt are you using?
A fixed one, like in the ode/demo dir, or a properly timed one, based on a

If you use a fixed one, this behaviour can be caused by a video driver
If your graphics card 'syncs to vblank' you will typically get no more than
60 updates per second.
So maybe you did more than switch to 32 bit? You also use a different
display driver setting?

If you are using a clock based dt, then your comment on realtime vs
0.03times realtime is confusing.
