: Extract the ZIP file and run WinTimerTester.exe . No installation is required. Once open, the interface is simple. Press the "Start" button. You will see a live, updating frequency reading.
Using WinTimerTester was designed to be straightforward:
. For many applications, this is fine. However, for applications requiring high precision (like 240Hz+ gaming or emulators), a delay can lead to: WinTimerTester 1.1.zip
The application will display the current timer frequency (e.g., "Max Timer Resolution: 15.625ms").

is a lightweight, portable utility designed to measure the precision and frequency of Windows system timers. It is a staple tool for PC enthusiasts and gamers who want to diagnose micro-stuttering or optimize input latency by managing High Precision Event Timer (HPET) settings. Why Use WinTimerTester 1.1?
Note: Restart your PC. WinTimerTester should now read a flat 10.000 MHz (or your CPU's invariant equivalent) with a stable ratio. : Extract the ZIP file and run WinTimerTester
At its core, the application monitors two primary timing mechanisms: the GetTickCount and the QueryPerformanceCounter (QPC). In a perfectly stable environment, the ratio between these timers should be 1.0000. When this ratio fluctuates or deviates significantly, it indicates that the system's high-precision timers—such as the High Precision Event Timer (HPET) or the CPU's invariant Time Stamp Counter (TSC)—are misconfigured or experiencing "drift."
