Raise the clock interrupt frequency in Windows
See Fixing timing precision in Windows after the "The Great Rule Change" for a detailed explanation regarding restoring the old timer resolution implementation otherwise nothing below will make sense.
MeasureSleep is used to measure the precision of Sleep(1). The closer it sleeps to 1ms in reality, the better.
SetTimerResolution queries and sets the maximum timer resolution applicable to the system (usually 0.5ms). To start it automatically on boot, you can place the binary in shell:startup.
On Windows Server 21H2+ and Windows 11+, the registry key below should also be used so that requesting a higher resolution is effective on a system-wide level rather than only the calling process.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel]
"GlobalTimerResolutionRequests"=dword:00000001
