Different PC hardware setups and BIOS configurations force Windows to adopt different types of system timers. Running WinTimerTester 1.1 will reveal which one your OS is locked into: QueryPerformanceFrequency Value Active Timer Type Description TSC + ACPI (Default Windows)
HPET is a standalone chip integrated into motherboard chipsets. It operates at a fixed frequency of . While highly accurate over long durations, calling HPET forces the CPU to query the motherboard southbridge. This introduces physical execution latency, which can degrade DPC performance and lower maximum FPS in CPU-bound games. 3. Combination Timers (ACPI/LAPIC)

If you require absolute synchronization for hardware accessories or old game engines, force Windows to use HPET exclusively. First, ensure HPET is toggled inside your motherboard's BIOS/UEFI menus. Then execute: bcdedit /set useplatformclock true Use code with caution.
