# 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
|
|
|
|
1. Copy the file `er-patcher` to the game directory.
|
|
2. 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%`
|
|
3. Launch the game through steam. `er-patcher` automatically launches a patched version of `eldenring.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.
