An in-depth perspective on Default R6 Sensitivity Multiplier Explained: the Exact Config Numbers and in-Game Proof, bringing you critical context.

Editing local files requires careful attention to Ubisoft Connect's automated cloud backups, which can overwrite manual adjustments if not handled properly.

  1. Close Rainbow Six Siege completely. Never edit `GameSettings.ini` while the game client or anti-cheat service runs in the background.
  2. Navigate to the settings folder: Press `Windows Key + R`, type `%USERPROFILE%\Documents\My Games\Rainbow Six - Siege`, and press Enter.
  3. Select your active profile: If multiple accounts have logged into your PC, you will see several folders with long strings of numbers and letters. Open the folder modified most recently.
  4. Create a manual backup: Duplicate `GameSettings.ini` and rename the copy `GameSettings_backup.ini`.
  5. Adjust the multiplier: Open `GameSettings.ini` using Notepad. Press `Ctrl + F`, search for `MouseSensitivityMultiplierUnit`, and change `0.020000` to your desired figure (such as `0.002000`).
  6. Save and secure the file: Save the text file. If Ubisoft Connect frequently resets your preferences, right-click `GameSettings.ini`, select Properties, check Read-only, and click Apply. Keep in mind that making the file read-only prevents in-game graphical changes from saving until you uncheck it.

Once you launch Siege, check your sensitivity menu. If you cut the multiplier from 0.02 to 0.002, multiply your previous in-game hipfire numbers by 10 to restore your prior physical turn distance.
