KF2: Disable Mouse Acceleration in KFGame.ini

Mouse acceleration makes the cursor travel farther the faster you move the mouse, so the same hand movement gives different aim distances. In any shooter it is the first thing most players turn off, and Killing Floor 2 hides the switch in a config file. This guide (originally written in Russian) shows how to change it.

What mouse acceleration is

Acceleration scales how far the pointer moves depending on the speed of your hand. A low value means you have to push the mouse harder for the pointer to move; a high value makes the pointer fly across the screen with little effort. For consistent aim and muscle memory you want it off.

Steps

1. Open your Documents folder (use the Start menu shortcut if needed).
2. Go to My Games > KillingFloor2 > KFGame > Config and open KFGame.ini in Notepad.
3. Search for Acceleration=12.0 (Ctrl+F in Notepad; the original author mentions Ctrl+G).
4. Change it to Acceleration=0.
5. Save the file and close it, then start the game.
