Does mouse sensitivity affect aiming accuracy?
The short answer
Sensitivity significantly affects aiming style, but there is no universally optimal setting. The right sensitivity is the one that makes your flick shots accurate while still allowing fine microadjustments - and this depends on your arm length, desk space, and the specific games you play.
The data
| Setting | Effect | Pro player range |
|---|---|---|
| DPI (dots per inch) | Sensor sensitivity - higher = faster cursor per inch | 400–800 DPI |
| In-game sensitivity multiplier | Scales on top of DPI | Varies by game |
| eDPI (effective DPI) | DPI × in-game sens - the true comparable metric | 200–800 eDPI for FPS |
| Polling rate (Hz) | How often mouse reports position - 1000Hz is standard | 1000Hz |
| Mouse acceleration | Inconsistency multiplier - always disable | Off |
What it means for you
Lower sensitivity (low eDPI) favours precise tracking and microadjustments but requires more desk space and arm movement. Higher sensitivity favours fast flicks but sacrifices fine control. Most professional FPS players land between 200–800 eDPI. Benchmark your time per target on the Aim Trainer test at your current settings before experimenting.

Quick Answer
Yes - but the optimal setting is individual, not universal. Most professional FPS players use 400–800 DPI with low in-game sensitivity (eDPI 200–800). Sensitivity mainly affects the flick-vs-tracking tradeoff.
