Beyond Citadel: How to Fix Mouse Input Issue

Many players of Beyond Citadel have experienced issues with sporadic mouse input during gameplay, particularly when attempting to aim or fire. This guide provides a straightforward solution to resolve these issues by adjusting the game settings.

 

Problem Description

This fix aims to solve the issue of missed left or right mouse button clicks during gameplay. Very apparent when looking from side to side and trying to fire or aim down sights. Occurs often when turning while entering new rooms or performing lean and fire functions.

It seems to stem from the game running in windowed mode even while in fullscreen and your clicks sometimes dragging and resizing the game window. This can be easily tested by performing an alt + enter in game and trying to play in a smaller window, you’ll see the resizing causing missed clicks and creating a resizing effect in game.

Shoutout to Puto_Trash_Actual for pointing me in the right direction, thank you!

Locate Your GameUserSettings.ini

First, locate your GameUserSettings.ini file. To do this, go to your Windows installation drive then proceed in the following order:

Users > YOUR NAME > AppData > Local > beyond_citadel > Saved > Config > WindowsNoEditor > GameUserSettings.ini

Edit GameUserSettings.ini File

Open the GameUserSettings.ini file in a text editor and proceed to the [/script/engine.gameusersettings] section.

In this section, change the following:

  • Anything with RESOLUTION keyword to your native desktop resolution.
  • Anything with FULLSCREEN keyword to 0.
  • bUseVSync to True (not sure if this is required, but it helped with my screen tearing issues in-game)

Save the changes to the file and launch the game, mouse input problems should be gone.

Example Configuration

Here is the [/script/engine.gameusersettings] portion of my GameUserSettings.ini that works. Set for 4k monitor resolution.
[/script/engine.gameusersettings]
