Call timeBeginPeriod() and then write a function to measure sleep(1) granularity.. it should return about 1.95 (ie: sleep(1) will return 1.95 while timeBeginPeriod() is being run)

It sounds like your knowledge of hardware is beyond mine. When I said 1ms, that was based on the Microsoft documentation for the api: timeBeginPeriod The timeBeginPeriod function sets the minimum timer resolution for an application or device driver. MMRESULT timeBeginPeriod( UINT uPeriod ); Parameters uPeriod Minimum timer resolution, in milliseconds, for the application or device driver. No matter what, it seems pretty clear that the practical ceiling for srds is 512fps.
