Actually there is (QueryHighPerformanceCounter). It's accuracy it's better
that 1 ms. But my code it's faster and more accurate.
You can use it as a timer if you poll it constantly from a thread. This
technique was widely used on Windows (althrough with probably another timer,
like GetTickCount) for low latency DirectSound apps before the new driver
model WDM.
