Trying to find out why I was runing at 1ms, I did a bit of seraching and came across this
handy hint, (especially useful for laptops):
Open a Cmd windows as Administrator and run "powercfg -energy duration 5"
It gives a comprehensive report of what settings and applications are "energy hogs" and let
me identify the one background application that was increasing the timer frequency
(resulting in more power used).
