direct motion?

Hi to all,
Is there anybody in this group that uses the software from direct
motion?
They claim that the software runs at a realtime base under windoze95
and 98.
All the loops are closed in the software itself without the use of a
external card!
It does have a box that is connected over USB2.0 to send the commands
to.
Now i would love to know how "realtime"it really is?
Any feedback will be appriciated.
Thx,
Marc
