Learn the steps to turn off mouse smoothing and acceleration in South of Midnight. Achieve optimal gameplay with better accuracy and responsiveness.

If you've jumped into the atmospheric world of South of Midnight on PC and found the mouse movement feeling a bit unresponsive or "floaty," you're not alone. Many players have experienced a sense of imprecision when trying to look around, likely due to default settings for mouse smoothing and/or acceleration. While these features might be intended to create a smoother, more cinematic feel, they can often hinder precise aiming and quick camera movements, leading to a sluggish experience for keyboard and mouse users.It appears the game's initial mouse controls were perhaps tuned more with controllers in mind, leaving PC players seeking a more direct and raw input response. Unfortunately, South of Midnight currently lacks an in-game toggle to disable these effects. However, the developers have acknowledged this feedback and provided a workaround involving editing configuration files. Additionally, a patch has been released to extend the mouse sensitivity slider for finer adjustments.Here's a comprehensive guide on how to disable mouse smoothing and acceleration in South of Midnight on PC to achieve a more responsive feel.

South of Midnight Disable Mouse Smoothing/Acceleration: The Workaround

Fortunately, the developers at Compulsion Games have listened to player feedback and offered a method to mitigate or eliminate mouse smoothing and acceleration. Remember to ensure your game is updated to the latest version, as a patch has already increased the range of the in-game mouse sensitivity slider. If the issue persists after updating, follow these steps:

How to Disable Mouse Smoothing/Acceleration:

  • Check Windows Mouse Settings: Before diving into game files, it's worth checking your mouse settingsat the Windows level. Incorrect Windows settings can exacerbate inputissues in games.

    • Go to Windows Control Panel.
    • Select Mouse.
    • Navigate to the Pointer Options tab.
    • Ensure "Enhance pointer precision" is unchecked. This feature adds mouse acceleration and can negatively impact the feel in games.
    • Adjust the pointer speed slider to a comfortable level.
    • Click Apply and then OK.
  • Access Game Configuration Files: Make sure South of Midnight is not running before proceeding. Open File Explorer and type or paste the following path into the address bar:

    %LOCALAPPDATA%\SouthOfMidnight\Saved\Config\WindowsNoEditor

    Press Enter.

  • Locate or Create Input.ini: Inside the WindowsNoEditor folder, look for a file named Input.ini.

    • If the file exists: Open it with a text editor (like Notepad).
    • If the file does not exist: Right-click in the folder, select New, then Text Document. Rename the new file to Input.ini and open it.
  • Paste Configuration Text: Paste the following block of text directly into the Input.ini file:

    • [/script/engine.inputsettings]bEnableMouseSmoothing=False 
    • AxisConfig=(AxisKeyName="MouseX",AxisProperties= (DeadZone=0.000000,Sensitivity=0.700000,Exponent=1.000000,bInvert=False)) 
    • AxisConfig=(AxisKeyName="MouseY",AxisProperties= (DeadZone=0.000000,Sensitivity=0.700000,Exponent=1.000000,bInvert=False))
  • Save the File: After pasting the text, save the Input.ini file.

  • Explanation of the Configuration:

    • bEnableMouseSmoothing=False: This line explicitly disables the built-in mouse smoothing.
    • AxisConfig=(AxisKeyName="MouseX", ...) and AxisConfig=(AxisKeyName="MouseY", ...): These lines configure the properties for horizontal (MouseX) and vertical (MouseY) mouse movement.
      • DeadZone=0.000000: Sets no dead zone for movement, ensuring even slight mouse movements are registered.
      • Sensitivity=0.700000: Controls the overall mouse sensitivity. You can adjust this value toyour preference. A higher value will result in faster cursor movement.
      • Exponent=1.000000: Sets a linear sensitivity curve, meaning there is no mouse acceleration.
      • bInvert=False: Ensures the mouse movement is not inverted.
  • Restart the Game: It's crucial to restart South of Midnight for these changes in the Input.ini file to take effect. The game only reads this configuration file upon startup.

  • Adjusting Sensitivity:

    The Sensitivity=0.700000 value is a starting point. You can increase or decrease this value tofine-tune your mouse sensitivity to your liking. Remember to restart the game each time you make changes to the Input.ini file to see the effect.


    Controller Fix (Right Stick Sensitivity):

    The guide also provides a method to improve the responsiveness of the right stick on a controller by editing the same Input.ini file. If you are using a controller and find the camera movement sluggish, you can add the following lines to the Input.ini file:

    • AxisConfig=(AxisKeyName="Gamepad_RightY",AxisProperties= (DeadZone=0.1,Sensitivity=7.000000,Exponent=1.000000,bInvert=False)) 
    • AxisConfig=(AxisKeyName="Gamepad_RightX",AxisProperties= (DeadZone=0.1,Sensitivity=7.000000,Exponent=1.000000,bInvert=False))

    The default sensitivity for the right stick is mentioned as 0.07, so this significantly increases responsiveness. However, a value of 7.0 might be too high for some players. It's recommended to start with a lower value like 1.5 or 2.0 and fine-tune it to your preference.

    By following these steps, you can temporarily disable mouse smoothing andacceleration in South of Midnight on PC, leading to a more direct andresponsive control experience. The developers have indicated that aproper in-game option for these settings is in development, which willhopefully provide a more convenient solution in the future. Enjoy a more precise and less floaty control over your exploration of the South!
