Sets GlobalTimerResolutionRequests = 1. Since Windows 10 2004, a high-resolution timer requested by one process (e.g. a game calling timeBeginPeriod(1)) only applies to that process. This key restores the pre-2004 system-wide behaviour, so the lower timer period applies globally — improving frame-pacing and input-latency consistency in titles that rely on it. Reboot required.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
