A little-known feature called mouse acceleration has been messing up our aim since Windows XP. Why is it enabled by default? Who knows? Why is it called “enhance pointer precision”? An even bigger mystery.

Disable it though and you’ll notice more consistent mouse movements immediately. This might be the edge you need to reach that next rank in Overwatch or CS:GO. 🙂

This guide will teach you how to turn off mouse acceleration on almost every operating system and game that needs it.

What does mouse acceleration do?

With mouse acceleration is ON, the faster you move your mouse, the further your cursor will go.

This feature is useful to make the most of a small mouse space but can be detrimental for activities that require accurate mouse movements.

Turning OFF mouse acceleration allows your mouse and cursor to travel at a 1:1 ratio with no relation to speed.

In theory, this improved consistency allows you to train your muscle memory better. Most professional gamers disable mouse acceleration for this reason.

How to disable mouse acceleration

To avoid all instances of mouse accel, you’ll need to disable it in both your operating system and in-game settings. Find your relevant instructions below.

Operating Systems

Windows 10
Step 1: Open up your Start Menu and type in “mouse”. Go to Mouse Settings.

Step 2: Click on Additional mouse options.

Step 3: Go to the Pointer Options tab and uncheck Enhance pointer precision.

Step 4: Click Apply and OK.

Windows 7 & 8

Note: These screenshots are from Windows 8, but the steps for Windows 7 are exactly the same.

Step 1: Open up your Start Menu and type in “mouse”. Click on Mouse.

Step 2: Go to the Pointer Options tab and uncheck Enhance pointer precision.

Step 3: Click Apply and OK.


Step 1: Open Terminal, located in the Utilities folder in Applications.

Step 1a (optional): To check your current mouse acceleration settings, type in the following command and hit Enter.

defaults read .GlobalPreferences

Step 2: Type in the following command and hit Enter to disable mouse acceleration.

defaults write .GlobalPreferences -1

Step 3: Restart your Mac to apply changes.


Step 1: Click on the cog icon in the main menu to go to settings.

CS:GO settings

Step 2: Go to Keyboard/Mouse > Keyboard & Mouse Settings.

Keyboard/Mouse section in CS:GO settings

Step 3: Turn Raw Input ON and Mouse Acceleration OFF .

Turn off CS:GO mouse acceleration.

Your settings should save automatically.

Black Ops 2

Step 1: Right click the game in your Steam library and select Properties.


Step 3: Type in the following code and click OK.


Razer Synapse has also been known to cause mouse in Black Ops 2. Closing Razer Synapse before you launch your game fixes this.

Fallout 4

Step 1: Open the file Fallout4.ini in your Documents>My Games>Fallout4 folder.

Step 2: Scroll down to [Controls] and add the following code underneath.


Step 3: Open Fallout4Prefs.ini in the same folder and add the following code under [Display].


Step 4: Open Fallout4Prefs.ini in your game’s installation folder (C:\Program Files [x86]\Steam\steamapps\common\Fallout 4\Fallout4) and add the the same line under [Display].


Fallout: New Vegas
Step 1: Open Fallout_default.ini in your game’s installation folder (C:\Program Files [x86]\Steam\steamapps\common\Fallout New Vegas).

Step 2: Add the following lines of code under the [Controls] section.


Step 3: Save the file and you’re all set.


The line “bDisableMouseAcceleration=False” in GameUserSettings.ini caused players to believe Fortnite had mouse acceleration. But a Reddit comment by Epic Games’ Michael Noland confirms “there is no mouse acceleration or mouse smoothing in FN:BR.”

Monster Hunter World

Unfortunately, the erratic mouse movements you feel in Monster Hunter World isn’t caused by mouse acceleration. The game inaccurately inputs data from your mouse because it was built for game controllers. We suggest playing with a game controller.


Overwatch uses raw input so it is unaffected by any mouse acceleration.


Step 1: Go to \Program Files\Steam\steamapps\common\skyrim\Skyrim and open SkyrimPrefs.ini.

Step 2: Under [Controls], change “bMouseAcceleration=1” to “bMouseAcceleration=0“.

Step 3: Save the file and you’re done!

Other Mouse-Related Tweaks to Improve Your Aim

Your aiming potential just soared because you disabled “Enhance pointer precision”. Good stuff. But before you go off and train your aim with your new settings, you should know these additional tweaks you can make to help your cause.

Find your perfect sensitivity

Your mouse sensitivity is more consistent now that acceleration isn’t a factor. It’s crucial that you set it to a level you have maximum control. This will vary depending on your mouse grip and personal preferences.

When you have the time, try out the exercise explained in the video below by Professional Overwatch coach ioStux to find your perfect sensitivity.

Note: You’ll likely find that your sensitivity has been set too high. Playing on a lower sens will allow for more accuracy and fine adjustments, but you’ll need more space to move your arm. This might mean having to get a bigger mousepad like the SteelSeries QCK Large Cloth.

Speaking of mousepads…

Your Mousepad Actually Matters, A Lot

Mousepads have a more significant impact on your mouse movements than you’d think. In addition to getting a bigger one, you might also consider the following.

Cleaning Your Mousepad

The gunk that gathers on your mousepad over time is not only gross, it also adds random unnecessary friction. Clean your mousepad and you’ll be surprised how much better your mouse moves.

Switching from cloth to hard (or vice versa)

Most people are raised on cloth mousepads so a plastic or aluminum one doesn’t even cross their minds. I was in the same boat until I got my Razer Destructor 2. The varying friction of a cloth mousepad was no longer a factor and I was able to aim more precisely.

The situation might be the opposite for you if you’ve always used hard mousepads. You might like the additional friction of a soft mousepad, so try it out!

Get a Better Mouse

This one should be obvious but I thought it was worth mentioning. If you’re using a crappy Amazon Basics mouse or something that looks like this…

…no tweaks to your settings will save you. Consider investing in a mouse specifically designed for gaming, one that’s tuned for performance.

Too old a reference? Well, we hope this guide helps you get more headshots anyways, or whatever you need better aim for.

We plan to constantly update this guide so that no matter what operating system or game you’re on, you can reference this to get rid of mouse acceleration. Let me know in the comments if there was anything I missed!
