GitHubThis patch provides frame-rate-independent raw mouse input and removes additional heavy mouse acceleration while preserving camera collision and normal character-turn smoothing. It modifies only the running process and does not alter game files on disk. Works up to 360hz without issues (in my experience).
CompatibilityAll the Assassin's Creed: Brotherhood versions that have matching layout and hook coordinates to the latest version documented in the repository are supported. The patch verifies the executable and guarded instructions before installing its hooks.
Before installingThis is an unofficial, experimental, largely AI-generated patch. Extract the archive into the directory containing AssassinsCreedBrotherhood.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)), load into the game normally and it should work by itself.
