Elden Ring Proton Patcher
A tool aimed at enhancing the experience when playing the game on linux through proton.
Warning
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!
Features
- 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
Usage
- Copy the file
er-patcher
to the game directory. - In steam, set the game launch options to
./er-patcher ARGS -- %command%
where ARGS is replaced with a combination of
-r RATE
or--rate RATE
for setting a custom framerate cap (default: 60)-u
or--ultrawide
for removing black bars-v
or--disable-vigniette
for removing the vigniette overlay- Example:
./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-patcher
automatically launches a patched version ofeldenring.exe
with EAC disabled.
Windows
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.
