Launcher of Choice

While the Epic Games Launcher works through wine, it has a lot of issues and does not work through Proton at all. Because of that, we recommend (and all further wiki articles assume you are) using Legendary.

Wine/Proton version management

Legendary uses a config file located at ~/.config/legendary/config.ini to configure what runner to use. Create a new entry for the game you wish to configure like so:

[AppName]
; options for AppName

then add options below. Both the wine_exec and wrapper keys can be used to configure what runner to use, with the wrapper option requiring the no_wine key also set to true:

[AppName]
wine_exec = /path/to/wine

OR

[AppName]
no_wine = true
wrapper = /path/to/wrapper

Wine/Proton prefix

The wine/proton prefix is configured using an environment variable. These can also be set in the config file

[AppName.env]
; Environment variables set for AppName

Wine prefix can be set with the WINEPREFIX variable, while Proton prefixes use STEAM_COMPAT_DATA_PATH

[AppName.env]
WINEPREFIX = /path/to/wine/prefix

OR

[AppName.env]
STEAM_COMPAT_DATA_PATH = /path/to/proton/prefix
