Launch the game through steam. `er-patcher` automatically launches a patched version of `eldenring.exe` with EAC disabled. Note: There might be some distros (e.g. older Ubuntu releases) that launch python 2 instead of 3 when running `python`. In that case you'll need to replace `python` with `python3` in the launch option line. ## Features -| Argument | Description | -| --------------------------------------- | --------------------------------------------------------------------------------------------------------- | -| `-r RATE` or `--rate RATE` | Set a custom framerate limit (default: 60). | -| `-x EXE` or `--executable EXE` | The executable to launch, relative to the games folder.

edges or for distant entities. | -| `-s` or `--skip-intro` | Skip intro logos at game start. | -| `-f` or `--remove-60hz-fullscreen` | Remove the 60Hz limit in fullscreen

As long the flag `--with-eac` is not set, the tool modifies the steam launch command to launch the patched executable instead of `start_protected_game.exe`, thefore ensuring that the patched exe is never run with EAC enabled.
