World War 3 – Mouse Input Fix

A Simple guide for the Mouse Issues that come with every Unreal Engine Game.

What Mouse Input Issues?

Essentially the way most games, especially Unreal Engine ones handle Mouse Input, is by calculating Mouse Movement pretty far back. Therefore if your CPU cant keep up, itll cause the mouse to slow down.

That’s a yikes isn’t it? But luckily we can fix it!

Fixing the Mouse Issues!

First thing we have to do is get to the games config files.

Which are located here:

  • C:\Users\UserName\AppData\Local\WW3\Saved\Config\WindowsClient

Once youre there, open GameUserSettings.ini with your notepad and in there we’ll search(F3) for “RawMouseInput”. It should look like this:

When you have that, change the False to True, behind that add a “,” and add “bEnableMouseSmoothing=False”.

Make sure there is a , after each command and no spaces. The line should read somethingxyz,RawMouseInputEnabled=True,bEnableMouseSmoothing=False,Invertxyz

Match it with my screenshot if youre confused!

For good measure cause some versions of the Unreal Engine are a bit different and to make sure it works, we can also open input.ini from the same Folder and right beneath [/script/engine.inputsettings] we’ll add

  • RawMouseInputEnabled=True
  • bEnableMouseSmoothing=False

And thats it, enjoy the game with 0 mouse issues.

Also yes, this works on other Unreal Engine games too.

P.S. By using this Guide you agree to not shoot at me when Im in your match.
