What is Polling Rate?

Polling rate is the frequency at which a mouse reports its position to the computer. Measured in Hz (Hertz), a 1000Hz polling rate means the mouse sends position data 1000 times per second. Higher polling rates provide smoother and more accurate mouse movement.

Common Polling Rates

125Hz - Default setting (8ms interval)
250Hz - Medium setting (4ms interval)
500Hz - Gaming mouse default (2ms interval)
1000Hz - High-performance gaming (1ms interval)

Measurement Tips

Move your mouse quickly and smoothly for accurate measurement
Wired mice connected directly to USB ports are most accurate
Wireless mice may show variations depending on connection quality
Browser and OS limitations may result in lower measured values

Frequently Asked Questions

Polling rate refers to the frequency at which a mouse sends its position data to the computer. It is expressed in Hz (Hertz) indicating how many times per second the data is sent. A higher value means the position is reported more frequently, resulting in smoother and more accurate cursor movement.

125Hz sends position data 125 times per second (8ms interval), 500Hz sends 500 times per second (2ms interval), and 1000Hz sends 1000 times per second (1ms interval). Some modern high-performance gaming mice support up to 4000Hz or 8000Hz. Higher values mean less input lag.

A low polling rate creates a delay between mouse movement and on-screen response, which is a disadvantage in situations requiring precise control such as FPS games. A polling rate of 1000Hz or higher minimizes input lag, enabling faster and more accurate aiming and movement.

Most gaming mice allow you to change the polling rate through dedicated software (e.g., Logitech G Hub, Razer Synapse). Connecting directly to a PC's USB port instead of through a USB hub helps maintain a more stable polling rate. Wireless mice may have a lower polling rate compared to wired mice.

How Polling Rate Works and Mouse Performance

How Polling Rate Affects Mouse Performance

Polling rate is one of the key factors that determines mouse responsiveness. A 1000Hz mouse updates its position every 1ms, providing near real-time response. A 125Hz mouse, on the other hand, updates every 8ms, which can make the cursor appear to stutter during fast movements. That said, the DPI and tracking accuracy of the mouse sensor are just as important as the polling rate.

Relationship with Overall Mouse Performance

High polling rate mice can slightly increase CPU load. Ultra-high polling rate mice at 4000Hz or above may cause performance issues on some systems, so it's important to choose a polling rate that matches your system specs and gaming environment. For typical gaming setups, 1000Hz provides the optimal balance.
