@ -20,15 +20,16 @@ A tool aimed at enhancing the experience when playing the game on linux through
- `-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%`
- `-c` or `--disable-ca` for disabling chromatic abberation
- Example: `./er-patcher --rate 30 -uvc -- %command%`
- Example with mangohud and wine fullscreen fsr: `./er-patcher --rate 144 -uvc -- 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%`
> `python er-patcher --rate 165 -uvc -- %command%`
## How it works
