This is not quite correct. Even older versions of the NTP port for Windows have tried to interpolate the timer ticks using the performance counter. Recent versions can optionally set the Windows multimedia timer to highest resolution because otherwise the Windows system time would seem to step back and forth when another application which makes use of the multimedia timer was started/stopped. So this is just another workaround for constrains due to Windows. This workaround is enabled by default if NTP is installed using the GUI setup program available from Meinberg, but can also be disabled during installation.
