Best mouse settings for MW3

The mouse is an essential tool for precise aiming and swift movement in Call of Duty Modern Warfare 3. Finding the right sensitivity and customizing key bindings can greatly enhance your gameplay experience. Before starting, make sure you set your ‘Aiming Input Device’ to ‘Mouse’ in the MW3 settings menu. Here are some recommended mouse settings to consider:

Vertical Aim Axis

The vertical aim axis setting determines how your mouse movement affects vertical aiming. It’s generally best to keep this setting at the standard setting to ensure intuitive and natural vertical aiming.

Aim down Sight Sensitivity

The aim down sight (ADS) sensitivity determines how your mouse movement translates when aiming down the sights of your weapon. It’s generally recommended to keep the ADS sensitivity at 1.0 to maintain consistent aiming across different scenarios.

Custom Sensitivity per Zoom

Some players prefer to have different sensitivity settings for different zoom levels, such as when using a sniper rifle compared to a handgun. However, for most players, it’s recommended to turn off the custom sensitivity per zoom option to maintain a consistent feel throughout the game.

Mouse Calibration

To further optimize your mouse settings, it’s important to adjust certain calibration options. These calibration settings help eliminate unwanted mouse acceleration, filtering, and smoothing, providing a more precise and reliable input for your gameplay.

Here are some recommended calibration settings:

  • Mouse Acceleration: 0
  • Mouse Filtering: 0
  • Mouse Smoothing: Off
  • Mouse Wheel Delay: 75

What’s the best sensitivity for keyboard and mouse in MW3?

Adjusting your mouse sensitivity is crucial for achieving accurate and responsive aiming. Experiment with different sensitivity levels based on your DPI (dots per inch) to find the optimal setting that allows you to flick from side to side with ease. We recommend starting with a sensitivity of 7 and making adjustments as needed. If the sensitivity feels too fast, you can lower it to 6 for better control.
