Elden Ring Proton Patcher
A tool aimed at enhancing the experience when playing the game on linux through proton.
This tool is based on patching the game executable through hex-edits. However it is done in a safe and non-destructive way, that ensures the patched executable is never run with EAC enabled. Use at your own risk!
- set custom frame time limits (e.g. 30, 90, 165, …)
- disable black borders when using resolutions with an aspect ratio other than 16:9 (e.g. ultrawide).
- vigniette removal
- Copy the file
er-patcherto the game directory.
- In steam, set the game launch options to
./er-patcher ARGS -- %command%where ARGS is replaced with a combination of
--rate RATEfor setting a custom framerate cap (default: 60)
--ultrawidefor removing black bars
--disable-vigniettefor removing the vigniette overlay
./er-patcher --rate 30 -uv -- %command%
- Example with mangohud and wine fullscreen fsr:
./er-patcher --rate 144 -uv -- env WINE_FULLSCREEN_FSR=1 MANGOHUD=1 MANGOHUD_CONFIG=histogram %command%
- Launch the game through steam.
er-patcherautomatically launches a patched version of
eldenring.exewith EAC disabled.
It also work just as well on windows. The only difference is, that you need to run the script via your Python 3 installation. The following launch option line works in case you installed Python from Microsoft Store:
python er-patcher --rate 165 -uv -- %command%
How it works
When the game is launched through steam, the tool creates a patched version of
eldenring.exe in a temporary subdirectory while leaving the original intact. The tool then modifies the steam launch command to launch the patched executable instead of
start_protected_game.exe. This ensures that the patched exe is never run with EAC enabled. After the game is closed, the patched executable is removed.
