Usually, no—but it can. A 1000Hz mouse reports its position and button state up to 1,000 times per second, or once every 1 millisecond. On a modern gaming PC with spare CPU capacity, the setting is generally safe and should not noticeably reduce FPS.
However, each report creates work for the USB and Windows input stack, mouse software, and the game. A CPU-bound game, older engine, thermally limited laptop, or inefficient input implementation can turn that extra work into lower FPS, worse 1% lows, or stutter that appears only while you move the mouse.

What does a 1000Hz polling rate mean?
Polling rate—also called report rate—is how often a mouse can send updates to the computer.

|---|---|
| 125Hz | 8ms |
| 250Hz | 4ms |

| 1000Hz | 1ms |
| 2000Hz | 0.5ms |
| 4000Hz | 0.25ms |
| 8000Hz | 0.125ms |
These are report intervals, not guaranteed end-to-end input latency. The mouse sensor, firmware, USB stack, Windows, the game’s input path, frame timing, display refresh rate, and rendering queue all affect when movement appears on screen. Razer’s timing examples document the conventional 125Hz, 500Hz, and 1000Hz intervals in its mouse manual.

Can 1000Hz reduce FPS?
It can, but the effect is workload-dependent and usually small on a system with adequate headroom. The mouse does not automatically take rendering work away from the GPU. The added cost is primarily in the CPU and software input path:
- The mouse generates more reports.
- USB and Windows receive those reports.
- Drivers, mouse utilities, overlays, or remapping tools may inspect them.
- The game processes the input and may update camera orientation, aiming, physics, or other state.
Microsoft’s raw-input documentation specifically discusses buffered handling for high-frequency devices such as 1000Hz mice, since multiple events can accumulate between application message-loop iterations.
The result depends on the game and the PC. If the game is GPU-bound, the GPU is already limiting frame production, so extra mouse-processing work is unlikely to create a meaningful FPS change. If it is CPU-bound, that work competes with the game thread, rendering submission, AI, physics, and other CPU tasks.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Razer says higher polling rates require more processing power and may reduce frame rates in CPU-bound games. Logitech likewise acknowledges that some users experience FPS drops at report rates above 1kHz and recommends lowering the rate as a test. Neither claim means that every 1000Hz mouse imposes a fixed CPU penalty.
Why does moving the mouse sometimes cause stutter?
This is one of the strongest clues that polling or input handling may be involved. A stationary mouse produces few meaningful movement events. Rapid movement produces a continuous stream of reports, and an inefficient game or utility may do relatively expensive work for each one.

Symptoms can include:
- FPS drops only during fast mouse movement.
- Worse 1% lows despite a reasonable average FPS.
- Uneven frame pacing or visible hitches.
- Brief freezes while aiming or turning.
- A spike on one CPU core or the game’s main thread.
Total CPU usage can be misleading. A single saturated game or render thread can limit FPS while Task Manager reports only 40–60% overall CPU usage. In that situation, 1000Hz may be the trigger that exposes an existing CPU limit rather than the only cause.
How much latency does 1000Hz save?
Moving from 125Hz to 1000Hz changes the nominal interval from 8ms to 1ms. Under ordinary assumptions, the average wait for the next report is roughly half each interval. NVIDIA’s system-latency guide states that 125Hz can add up to approximately 3ms of average system latency compared with 1000Hz.
The gain is not the same as removing 7ms from every click or movement. It is only one part of the total input-to-display path. The difference between 500Hz and 1000Hz is also much smaller: a nominal 2ms interval versus 1ms. Frame pacing, display refresh, game processing, sensor behavior, click latency, and the rendering pipeline may matter more in practice.
A higher report rate does not automatically improve aim. It can reduce polling delay, but stable frame times and reliable input are more valuable than a theoretical improvement that introduces stutter.
Which PCs and games are most vulnerable?
1000Hz is most likely to cause trouble when:
- The game is already CPU-bound or running at an extremely high FPS.
- The processor is older, mobile, power-limited, or thermally throttled.
- The game has inefficient raw-input or message-based input handling.
- The title uses an older engine that was not designed with high-report-rate mice in mind.
- Mouse utilities, RGB tools, macro engines, overlays, recorders, or monitoring programs are active.
- A Windows, game, driver, or peripheral-software update changed input behavior.
Razer notes that some older game engines may not handle high polling rates well. This does not mean every older game will fail, nor should severe 8000Hz problems automatically be attributed to ordinary 1000Hz operation.

1000Hz is less likely to matter when the GPU is clearly the bottleneck, the CPU has substantial per-frame headroom, the game handles raw input efficiently, or the mouse is not being moved continuously. Shader compilation, thermal throttling, a bad driver, network problems, and overlays can also produce symptoms that have nothing to do with polling rate.
How to test whether polling rate is causing FPS drops
Use a controlled A/B test rather than changing several settings at once.
1. Establish a repeatable scenario
Use the same game, map or training range, graphics settings, resolution, FPS cap, background applications, and mouse-movement pattern. Record average FPS, 1% lows, frame-time graphs, CPU and GPU utilization, clocks, and temperatures if possible.
2. Test at 1000Hz
Run the same movement-heavy scenario several times at 1000Hz. Move the mouse continuously and rapidly enough to reproduce the problem; a stationary-mouse test can produce a false negative.
3. Test at lower rates
Repeat the identical scenario at:
- 500Hz
- 250Hz
- 125Hz, optionally, as a diagnostic extreme
Do not change DPI, in-game sensitivity, resolution, graphics settings, or the FPS cap between tests.

4. Interpret the results
- No change: Polling rate is probably not the bottleneck.
- Only 1000Hz stutters during movement: Input processing is a credible cause.
- 500Hz fixes it: Keep 500Hz while investigating; its nominal interval is only 1ms slower than 1000Hz.
- Only 250Hz is stable: Look for driver, software, engine, Windows, or CPU-limit problems.
- Every rate behaves the same: Investigate thermals, shaders, drivers, overlays, GPU/CPU limits, and game settings.
- Only one game is affected: Suspect that game’s input implementation and test another title.
5. Examine frame times, not just FPS
A change from 240 to 220 FPS may be less damaging than repeated 20–50ms frame-time spikes during mouse movement. Check per-core CPU load and game-thread or render-thread utilization where available; total CPU usage alone is not sufficient. Also check GPU utilization, CPU/GPU clocks, temperatures, power limits, and input-related background processes.
What to do if lowering the rate helps
- Use 500Hz or 250Hz temporarily for stable frame pacing.
- Update the mouse firmware and configuration software.
- Update Windows and the game.
- Disable unnecessary overlays, RGB utilities, macro tools, recorders, and monitoring software.
- Try another USB port directly on the motherboard rather than through a hub.
- Test raw input enabled or disabled if the game offers that option.
- Re-test after each change.
- Return to 1000Hz if the underlying issue is fixed.
Menu names and input options vary by game and version, so there is no universal in-game path for changing raw-input behavior.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What polling rate should you use?
| Situation | Suggested setting |
|---|---|
| Modern system with stable frame times | 1000Hz |
| CPU-bound game or mild stutter | 500Hz |
| Persistent compatibility problem | 250Hz |
| Severe issue on older hardware | 125–250Hz |
| Troubleshooting 2000–8000Hz | Start at 1000Hz, then increase only if stable |
Use 1000Hz when the game is stable and the CPU has headroom. Use 500Hz when it solves intermittent stutter; it is often the best compatibility compromise. Use 250Hz or lower when hardware or a particular game cannot maintain stable frame pacing and the lower rate is acceptable for your games.
What about 2000Hz, 4000Hz, and 8000Hz?
Higher rates reduce the nominal report interval further, but they also increase the number of reports software may need to process. An 8000Hz mouse can report every 0.125ms—up to eight times as often as a 1000Hz mouse. Razer warns that CPU-bound systems may not have enough resources to process that volume of input.

That trade-off is more significant above 1000Hz, especially in CPU-limited games. If a high-rate mouse causes stutter, begin troubleshooting at 1000Hz rather than assuming the problem applies equally to every 1000Hz device.

Should you buy a higher-polling-rate mouse?
Not to solve an FPS problem. Lowering the rate is free and should be tested first.
If you are buying a mouse for other reasons, prioritize an adjustable polling rate, reliable firmware and software, accurate tracking, click latency, shape, weight, grip fit, and wireless reliability. The ability to return to 500Hz or 250Hz is useful when a particular game has compatibility problems.
A conventional 1000Hz configuration, such as the Razer DeathAdder V3 Pro 1000Hz version, is a reasonable example for someone who wants standard report-rate compatibility. It is not automatically the best mouse, and its price and availability can change. Paying a premium for a 4000Hz or 8000Hz model solely because you are experiencing CPU bottlenecks is difficult to justify.

Keep your mouse at 1000Hz unless a controlled test shows FPS loss or frame-time spikes, particularly while moving the mouse. On a modern, adequately powered gaming PC, 1000Hz is generally a sensible default. If it causes instability, try 500Hz first; a stable 500Hz experience is preferable to a stuttery 1000Hz or 8000Hz experience.
