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.
Thats a yikes isnt it?
But luckily we can fix it!

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.
