Is Your Mouse Holding You Back? Real-Time Hz Tester
In competitive gaming, every millisecond counts. Your mouse's Polling Rate determines how often it reports its position to your computer. A low polling rate causes input lag and micro-stuttering, making it impossible to aim precisely in fast-paced shooters like CS:GO, Valorant, or Overwatch. Our Mouse Polling Rate Tester analyzes the signal frequency of your device in real-time, visualizing exactly how consistent and fast your hardware really is.
How to Use This Test
To get an accurate reading, simply click the "Start" button and move your mouse continuously in fast circles.
- Don't Stop Moving: The polling rate drops to 0Hz when the mouse is stationary to save power. You only see the max speed while in motion.
- Consistency is Key: A good gaming mouse shouldn't just hit 1000Hz once; it should stay near 1000Hz consistently. If your graph jumps wildly between 500Hz and 1000Hz, you may have a sensor issue or a dirty mousepad.
Understanding the Numbers
Most modern mice fall into one of these standard categories:
- 125 Hz (8ms delay): Standard office mice. Fine for browsing, terrible for gaming. Movement feels "floaty."
- 500 Hz (2ms delay): The old standard for wireless gaming mice. Very stable and battery-efficient.
- 1000 Hz (1ms delay): The gold standard for wired esports mice. Provides smooth, responsive tracking.
- 4000 Hz / 8000 Hz (0.125ms delay): The cutting edge. Found in high-end mice (like Razer Viper 8K). Note: This requires a powerful CPU to run smoothly.
1000Hz vs. 500Hz: Which is Better?
While 1000Hz is technically faster, it uses more CPU power and drains wireless batteries faster. Many pro gamers actually prefer 500Hz because it feels more "stable" on older PC setups. If your mouse allows it, try both settings in this tester. If you see the 1000Hz line fluctuating wildly (dropping to 600Hz often), you are better off locking it to a stable 500Hz.
Frequently Asked Questions
Why is my polling rate fluctuating?
This is normal. The mouse only sends data when it detects movement. If you move slowly, it sends fewer reports. To test the maximum capability, you must move the mouse quickly.
Does polling rate affect FPS?
Indirectly, yes. Extremely high polling rates (4000Hz+) can overwhelm older CPUs, causing frame drops in games. If you experience lag after buying a new 8K mouse, try lowering the rate to 1000Hz.
Can I test my keyboard here?
No. Keyboards function differently and don't send continuous coordinate data like mice do. This tool is specifically designed for mouse sensor reporting.
