Disabling Mouse Acceleration in Fortnite BR

Mouse acceleration changes your cursor speed based on how fast you move your mouse, which can make aiming inconsistent and unpredictable. Most competitive players disable mouse acceleration to ensure their aim is consistent regardless of how quickly they flick or track targets.

This guide covers how to disable mouse acceleration both in Fortnite’s config files and in Windows settings, plus optimal mouse sensitivity recommendations for competitive play.

Does Fortnite Have Mouse Acceleration?

According to Epic Games, Fortnite uses raw mouse input and doesn’t apply mouse acceleration or smoothing to your aim. However, many players still experience inconsistent aim due to Windows-level mouse acceleration settings or config file values.

To ensure the smoothest, most consistent aiming experience, it’s recommended to disable mouse acceleration both in Fortnite’s configuration files and in Windows settings.

Method 1: Edit Fortnite Config File

You can manually disable mouse acceleration in Fortnite by editing the game’s configuration file:

1. Press Windows + R to open the Run dialog
2. Type %localappdata% and press Enter
3. Navigate to FortniteGame > Saved > Config > WindowsClient
4. Right-click GameUserSettings.ini and select Properties
5. Uncheck “Read-only” if it’s enabled, then click Apply and OK
6. Right-click the file again and open it with Notepad
7. Press Ctrl + F to search and look for bDisableMouseAcceleration
8. Change the value from False to True
9. Save the file (Ctrl + S)
10. Right-click the file, go to Properties, and check “Read-only” to prevent Fortnite from resetting your changes

The full file path is typically:

C:\Users\YourUsername\AppData\Local\FortniteGame\Saved\Config\WindowsClient\GameUserSettings.ini

Why Set Read-Only?

Fortnite can reset your configuration settings when the game updates or sometimes when you change settings in-game. Setting the file to read-only prevents Fortnite from overwriting your mouse acceleration preference. The downside is that other settings changes you make in-game may not save, so you may need to temporarily disable read-only if you want to adjust other settings.

Method 2: Disable Windows Mouse Acceleration

Windows has its own mouse acceleration feature called “Enhance pointer precision” that can affect your aim in games. Even if Fortnite uses raw input, disabling this Windows setting ensures consistent mouse behavior across all applications.

Windows 10

1. Open the Start menu and type mouse settings
2. Press Enter to open Mouse settings
3. Click Additional mouse options on the right side
4. Go to the Pointer Options tab
5. Uncheck Enhance pointer precision
6. Set the pointer speed slider to the middle (6/11)
7. Click Apply, then OK

Windows 11

1. Press the Windows key and search for Bluetooth & devices
2. Click Bluetooth & devices in the left panel
3. Scroll down and click Mouse
4. Under Related settings, click Additional mouse settings
5. Go to the Pointer Options tab
6. Uncheck Enhance pointer precision
7. Click Apply, then OK

Recommended Mouse Sensitivity Settings

Once you’ve disabled mouse acceleration, setting the right sensitivity is key for consistent aim. Most professional Fortnite players use relatively low sensitivities.

Understanding eDPI

eDPI (effective DPI) is the product of your mouse DPI and in-game sensitivity. It’s the best way to compare sensitivities across different setups:

eDPI = Mouse DPI × In-Game Sensitivity

For example, 800 DPI with 10% in-game sensitivity = 80 eDPI

Recommended Ranges

• Low sensitivity: Under 55 eDPI – More precise aim but requires more mouse movement
• Medium sensitivity: 55-90 eDPI – Good balance of precision and speed
• High sensitivity: Over 90 eDPI – Faster turns but less precise

Most pro players fall in the 45-80 eDPI range. A common starting point is 800 DPI with 8-10% in-game sensitivity (64-80 eDPI).

Pro Player Examples

• Bugha: ~51 eDPI
• EpikWhale: ~56 eDPI
• TaySon: ~46 eDPI

The majority of professional players use 800 DPI as their base, adjusting in-game sensitivity to achieve their preferred eDPI.

Building and Editing Sensitivity

Fortnite allows you to set separate sensitivity multipliers for building and editing, which can be increased up to 1000%. This lets you maintain low sensitivity for precise aiming while having faster camera movement when building.

To adjust these settings:

1. Open Settings and go to the Mouse and Keyboard tab
2. Find Mouse Sensitivity – Building and Mouse Sensitivity – Editing
3. Increase these above 100% if you want faster building/editing without affecting combat aim

Many players set building sensitivity between 150-200% while keeping their base sensitivity low for accurate shots.

Additional Tips for Better Aim

Keep X and Y sensitivity the same: Using different horizontal and vertical sensitivities can make diagonal tracking feel inconsistent. Most pros keep these values identical.

Use a large mousepad: Lower sensitivities require more physical mouse movement. A large mousepad (at least 400mm wide) gives you room to make big swipes without running out of space.

Adjust gradually: If you’re changing your sensitivity significantly, give yourself time to adjust. Your muscle memory needs time to adapt to new settings.

Practice in Creative: Use aim training maps in Creative mode to dial in your sensitivity before jumping into real matches.

Check your mouse software: Some gaming mice have their own acceleration or angle snapping features. Check your mouse’s software (Logitech G Hub, Razer Synapse, etc.) and disable any acceleration or smoothing options there as well.

Troubleshooting

Settings keep resetting: Make sure you set GameUserSettings.ini to read-only after making changes. If the file doesn’t exist, launch Fortnite once to generate it.

Aim still feels inconsistent: Check that Windows “Enhance pointer precision” is disabled, and verify your mouse software doesn’t have acceleration enabled.

Can’t find the config file: Make sure you’re looking in AppData\Local (not AppData\Roaming). You may need to show hidden files in Windows Explorer to see the AppData folder.

Other settings not saving: If you’ve set the config file to read-only, you’ll need to temporarily remove the read-only flag to save other settings changes, then set it back to read-only afterward.
