Mouse acceleration significantly hinders performance in shooters, and Marvel Rivals is no exception. The game defaults to mouse acceleration with no in-game toggle to disable it. Here's how to rectify this:

Disabling Mouse Acceleration in Marvel Rivals

Since the game lacks an in-game option, you must edit the settings file:

1. Press Windows key + R, type %localappdata%, and press Enter.
2. Locate the "Marvel" folder, then navigate to "MarvelSavedConfigWindows".
3. Open "GameUserSettings.ini" with Notepad.
4. Add the following lines to the end of the file:

[/Script/Engine.InputSettings]
bEnableMouseSmoothing=False
bViewAccelerationEnabled=False

5. Save (Ctrl + S), close the file, right-click it, select "Properties", check "Read-only", and click "Apply" and "OK".

This disables mouse acceleration within the game.

Disabling Mouse Acceleration in Windows Settings

For complete consistency, disable it in Windows as well:

1. In the Windows search bar, type "Mouse" and select "Mouse settings".
2. Click "Additional mouse options" in the top right corner.
3. Go to the "Pointer Options" tab.
4. Uncheck "Enhance pointer precision".
5. Click "Apply" and "OK".

Understanding Mouse Acceleration and its Impact

Mouse acceleration alters your sensitivity based on mouse movement speed. Fast movements result in higher sensitivity, slow movements in lower sensitivity. While convenient for general use, this inconsistency is detrimental to aiming in shooters like Marvel Rivals. Consistent sensitivity is crucial for developing muscle memory and improving accuracy. Mouse acceleration prevents this muscle memory development.

With mouse acceleration disabled in both the game and Windows, you'll experience linear sensitivity, leading to improved aim and gameplay.

Marvel Rivals is available now on PS5, PC, and Xbox Series X|S.
