Mouse Sensitivity Settings Not Saving

Problem: Mouse sensitivity in the game resets to 3.00 after each map.

Solution #1: Direct Change in user.ini

  1. Go to the System folder in the game directory
  2. Open the user.ini file with Notepad
  3. Find the parameter MouseSensitivity=3.000000
  4. Change the value to what you need (e.g., MouseSensitivity=2.500000)
  5. Save the file

This method allows you to directly set the desired mouse sensitivity value that will be saved.

Solution #2: Setting "Read-only" Attribute

  1. Find the user.ini file in the System folder
  2. Right-click on the file
  3. Select "Properties"
  4. Check the "Read-only" box
  5. Click "OK"

This prevents the game from overwriting the file and preserves your settings.

Solution #3: Change from Main Menu

  1. Launch the game
  2. In the main menu (before connecting to server) change mouse sensitivity in settings
  3. Save settings
  4. Restart the game

This method sometimes helps if the problem is related to the order of loading settings.

Causes of the Problem

The problem may be related to:

  • Game localization — some localized versions have issues with saving settings
  • File access rights — the game cannot overwrite the settings file
  • Loading order — settings reset when connecting to server

Recommendations

  1. Try Solution #1 first — this is the most reliable method
  2. If the problem persists, use Solution #2 to protect the file from being overwritten
  3. Make sure you have write permissions in the System folder
  4. Create a backup of user.ini before making changes

Additional Information

The MouseSensitivity parameter is located in the [Engine.PlayerInput] section of the user.ini file. The value can be from 0.1 to 10.0, where a higher value means higher sensitivity.
