See the quoted post below:
Is there a way to do this for Windows 2000 or 2003 that is not a huge drama?
It would be fantastic to be able to run our Windows boxes at the exact FPS
we want to run them at, rather than some arbitrary number forced upon us by
the OS or hardware.

Turn off ACPI and run it as standard PC. HAL is the magic bullet when
it comes to server fps. Unfortunately, Standard PC removes the
ability to run SMP.
Or you could just bug valve to add a QueryPerformanceTimer() wrapper
on their sleep stuff to make it perform as good as other non microsloth OS's..

That is not exactly correct. HZ just increases/decreases the
granularity of operations like sleep() etc. Increasing HZ also
increases the chances of excess clock overhead.. HRT's like HPET are
good for time sensitive programs like game servers.. Using TSC on SMP
isn't a good idea unless you figured out a way to keep the clock's in
sync.. 8254 isn't SMP friendly, and ACPI-fast is slow to read (at
least on freebsd)
