Mouse polling rate is the number of position reports a mouse sends to your computer each second, measured in hertz (Hz). At 125 Hz, the mouse reports 125 times per second, with an 8-millisecond interval between reports. At 1,000 Hz, it reports every 1 millisecond.
A higher rate can make cursor movement and fast camera turns feel more consistent by reducing the time between reports. It does not eliminate display, game-engine, USB, or frame-rendering latency, and it can increase USB and CPU work. For most gaming PCs, 500–1,000 Hz is a sensible starting range. Test higher settings only when your game and system remain stable.
How mouse polling rate works
A mouse measures movement with its sensor and periodically sends an update to the computer. Polling rate, also called report rate, specifies how often those updates are sent. The number is not a speed rating for the sensor and does not describe DPI or sensitivity.
The nominal interval is calculated as one second divided by the polling rate. Logitech gives the practical example that a 125 Hz mouse sends 125 updates per second, or one update every 8 milliseconds. The equivalent intervals for common settings are:

| Polling rate | Reports per second | Nominal interval |
|---|---|---|
| 125 Hz | 125 | 8 ms |
| 500 Hz | 500 | 2 ms |
| 1,000 Hz | 1,000 | 1 ms |
| 2,000 Hz | 2,000 | 0.5 ms |
| 4,000 Hz | 4,000 | 0.25 ms |
| 8,000 Hz | 8,000 | 0.125 ms |
These figures describe the spacing of mouse reports only. They are not click-to-photon latency, the time from a physical movement to a changed pixel on your monitor, or a guarantee of a particular in-game response.
Does a higher polling rate reduce gaming latency?
It can reduce the portion of input delay caused by waiting for the next mouse report. Moving from 125 to 1,000 Hz changes the nominal interval from 8 ms to 1 ms, so the computer has more frequent opportunities to receive a fresh position. NVIDIA’s latency guide states that a low rate such as 125 Hz can add up to 3 ms of system latency on average compared with 1,000 Hz. That is NVIDIA’s stated comparison, not a result guaranteed for every mouse, game, or computer.
Total response time includes several other stages:
- The sensor detects movement and the mouse firmware processes it.
- The mouse waits for its next report opportunity and transmits data over USB, a wireless receiver, or Bluetooth.
- The operating system and game read the report and apply sensitivity, acceleration, and input processing.
- The game simulates a frame, and the CPU and GPU render it.
- The display scans and presents the finished frame.
Changing polling rate affects only the reporting stage. A game running with uneven frame times, a busy CPU, a slow rendering queue, or a high-latency display can outweigh the small difference between two report settings. A higher number therefore cannot by itself make someone aim better or guarantee a faster-looking response.

125 Hz versus 500 or 1,000 Hz
The jump from 125 Hz to 500 Hz or 1,000 Hz is the largest commonly encountered improvement in report frequency. At 125 Hz, cursor or camera movement is represented in 8 ms steps; at 1,000 Hz, the steps are 1 ms apart. The change may be easier to notice during rapid camera pans, high-refresh-rate use, or precise tracking than during ordinary desktop work.

500 Hz versus 1,000 Hz
Epic Games recommends trying rates in the 500–1,000 Hz range for performance and input response. Both settings are reasonable starting points for fast games. A 500 Hz mouse reports every 2 ms, while a 1,000 Hz mouse reports every 1 ms. Whether that single-millisecond interval matters depends on your game, frame pacing, monitor, and sensitivity.
1,000 Hz versus 2,000–8,000 Hz
RTINGS describes 1,000 Hz as the current industry standard for gaming and says the difference between 500 and 1,000 Hz is generally more noticeable than the difference between 1,000 and 8,000 Hz for most people. The same guide cautions that some games do not support rates above 1,000 Hz. Higher settings can also require more processing and generate more USB traffic, so a larger advertised number is not automatically an advantage.
How to choose a polling rate
Use the highest setting that your particular game and computer handle without unstable frame times, stutter, or unacceptable battery drain. The following is a practical decision framework rather than a universal rule:
Free tools Windows power users keep installed

| Use case | Starting point | What to check |
|---|---|---|
| Office work, browsing, and general desktop use | 125–500 Hz | Cursor smoothness and battery life |
| Competitive or fast-paced games | 500–1,000 Hz | Input feel, frame-time consistency, and game support |
| High-refresh-rate gaming with a compatible system | 1,000 Hz, then test higher | Whether the game supports the rate and whether CPU usage or stutter increases |
| Wireless gaming where long battery life matters | 500–1,000 Hz, or lower if acceptable | Battery runtime and connection stability |
There is no need to select 4,000 or 8,000 Hz merely because the mouse offers it. If two settings feel identical and the lower one gives steadier frame times or longer battery life, the lower setting is the better choice for your setup.

How to change mouse polling rate
The exact control depends on the mouse. It may be in the manufacturer’s configuration application, a physical button, onboard memory, or a combination of button presses. The label may be “Polling rate,” “Report rate,” or a value such as 1K.
- Check the supported values. Read the mouse manual or its configuration software. Do not assume that a wireless model supports the same rates over its receiver, cable, and Bluetooth.
- Connect the mouse in the mode you use for gaming. If you normally use a 2.4 GHz receiver, configure and test that connection rather than judging Bluetooth performance.
- Open the device settings. Select the mouse, find the polling/report-rate control, and choose 500 Hz or 1,000 Hz first. Save the setting to onboard memory when that option is available.
- Apply the change before launching the game. Some software applies it immediately; other utilities require a profile switch, reconnection, or a restart of the game.
- Test one setting at a time. Keep DPI, in-game sensitivity, graphics options, frame cap, and mouse acceleration unchanged so that the polling rate is the only variable.
- Try a higher value only if the baseline is stable. Move to 2,000, 4,000, or 8,000 Hz only when both the mouse and the game document support for that rate.
How to test whether a higher rate helps you
Subjective feel is useful, but it is easy to mistake a changed frame rate or sensitivity for a polling-rate improvement. Use a repeatable comparison:
- Choose a practice range, replay, or repeatable movement route in the game.
- Record the baseline at 500 or 1,000 Hz. Pay attention to slow tracking, rapid flicks, camera pans, and clicking while moving.
- Watch frame rate and, preferably, frame-time graphs. A higher average FPS does not compensate for new spikes or hitching.
- Switch only the polling rate and repeat the same movements for several minutes.
- Compare smoothness, input consistency, frame-time stability, and any visible cursor or camera irregularity.
- For a wireless mouse, check the battery estimate after normal use rather than judging from a short session.
Keep the setting that is consistently comfortable and stable. If you cannot reliably distinguish two settings and the lower one reduces system load, there is no practical reason to keep the higher value.
Why moving the mouse can cause FPS drops
Each report is a small USB or wireless transaction. At high rates, the number of transactions increases substantially. Logitech Support warns that additional USB traffic at higher report rates can affect system performance and cause FPS drops in some games. RTINGS likewise notes that taking advantage of rates above 1,000 Hz may require considerable processing power.

Symptoms
- Frame rate falls or frame-time spikes appear only while the mouse is moving.
- The game feels smooth when the mouse is still but stutters during camera movement.
- CPU usage rises after changing from 1,000 Hz to 2,000 Hz or higher.
- The problem occurs in one game but not on the desktop or in another game.
Fixes
- Return to 1,000 Hz and retest. If the problem remains, try 500 Hz.
- Close other hardware-monitoring, overlay, or peripheral utilities and test again.
- Use the mouse’s wired or dedicated 2.4 GHz receiver mode instead of Bluetooth for gaming, if supported.
- Check whether the game has a documented limit or compatibility issue above 1,000 Hz.
- Compare frame-time graphs, not just the FPS counter, and keep the highest stable rate rather than the highest selectable rate.
Wireless and Bluetooth considerations
Wireless operation does not automatically mean a lower polling rate. A mouse using a dedicated receiver may support 500, 1,000, or higher rates, depending on the model. The receiver, firmware, and configuration software determine which values are available.
Battery consumption is a separate trade-off. RTINGS identifies lower polling rates as one way to conserve wireless battery power. If a 1,000 Hz setting already feels smooth, reducing the rate can be reasonable when longer runtime matters more than a small reduction in report interval.
RTINGS also says Bluetooth polling is fixed at 125 Hz or less because of Bluetooth’s technical limitations. Treat that as general guidance and verify the specification for your exact mouse. Bluetooth can be convenient for travel and ordinary desktop use, but a dedicated receiver or cable is usually the appropriate mode when you need the mouse’s full gaming feature set.
Common misconceptions
“Higher polling rate increases DPI.”
It does not. DPI (or CPI) describes how much cursor movement the sensor reports for physical movement. Polling rate describes how frequently those measurements are delivered. You can change one without changing the other.

“8,000 Hz makes every game faster.”
No. The game must accept the reports, the system must process them, and the rest of the input-to-display path must be fast enough to expose a difference. Some games do not support rates above 1,000 Hz, and RTINGS characterizes the improvement above that point as marginal for most people.
“The highest setting is always best.”
A higher setting can increase USB traffic, CPU work, and wireless power use. If it introduces frame drops or inconsistent frame times, it is worse for play even though its nominal interval is shorter.
“Polling rate alone determines aim.”
Accuracy still depends on sensor tracking, ergonomics, sensitivity, practice, frame consistency, and display behavior. Polling rate is one input-latency variable, not a skill multiplier.

Bottom line for gamers
Start at 500 or 1,000 Hz, with 1,000 Hz serving as a practical baseline for a modern gaming setup. Test higher rates only in the game and connection mode you actually use. Keep the higher setting if it feels smoother without frame-time problems; otherwise step back to 1,000 Hz or 500 Hz. For wireless mice, include battery life in the decision, and do not expect any polling rate to overcome slow rendering, poor frame pacing, or a high-latency display.
