Amnesia: The Bunker FPS Unlock

Makes it so you can play at more than the maximum 120fps set by the game. Tested at 360hz (game didn't reach it but at least 200 :P).

To be clear, this is not a RIL release, this is only a targeted patch that actually changes the game code in a couple places to enable >120hz framerates; I only tested up to the generator room so there could be other issues later in the game; I do want to play it (this is my first time playing) so I will for sure fix issues if I encounter them eventually.

Amnesia The Bunker GOG Version 1.9 and Steam (the latest update as of Oct 2026), but the patch can probably work with other versions; only needs the correct calls sites and hooks, fails if there's a mismatch.

This is an unofficial, experimental, largely AI-generated patch. Back up your saves and expect that multiplayer, demos, overlays, ReShade, and other injectors may be incompatible. Extract the archive into the directory containing AmnesiaTheBunker.exe (make sure you either download the release with the bundled loader or otherwise that you already have an available ASI Loader installed in the game's root directory (like Ultimate ASI Loader)), then start the game normally.
