Mouse Input Problem Fix

Mouse fix for anyone having issues with sporadically missing left or right mouse button clicks during gameplay preventing aiming or firing.

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.

I see nothing in GameUserSettings.ini its blank ,Ive open it in notepad , am I doing something wrong ?

[angelvalue]

how do i make the game fullscreen

[luckyshot5135]

yea, even read only it managed to reset

[Abomination713]

Are you guys setting the file to read only after you make the changes? That should fix it defaulting back.

[luckyshot5135]

it defaulted back no matter what BUT I did find a solution, if you own borderless gaming it works on this.

[Vlesh]

If it keeps defaulting back, try opening the file properties and clicking Read Only.

Mine also seems to keep defaulting back
