Like you (I think, anyway), I don't have direct experience doing realtime
stuff under windows, but I don't share your optimism that a VxD will cure
the ills... There's simply too much other stuff happening in the OS that
assumes its not a realtime environment. I dunno if you could get a VxD
high enough in the interrupt food chain to ensure that it wasn't waiting
to process a keyclick or something.
I do know that NT supplies some real time stuff, but I havn't looked at it
closely enough to know if you can get down to 0.001 accuracy.

(and to whoever was posting that us actually measuring to 0.001 is silly,
I agree. There's quite simply _way_ too much that can go wrong for us to
just blindly accept that car A really went 0.001 faster than car B, just
because the timer said it did.)
