Guide to Uncap FPS
Opening Config Files
The first step in order to uncap our frame rate is to open Amnesia: The Bunker in the documents folder on your PC.
After this open the folder titled “Main” and find the configuration that starts with your username and ends with user settings.
Secondly, open this file and find the line that reads “RefreshRate=”60”, and the line that reads “GameplayUpdateRate=”60”.
All that’s needed to do now is update the value 60 in each line to whichever frame rate you want your game to run at, I have been running a buttery smooth 120-fps and am very relieved I don’t have to experience the game at 60 frames.
