This section is related to the development version of protonlaunch and those environment variables aren't available yet on the main release. Check out the protonlaunch faq to see what are the mainstream environment variables.
Protonlaunch comes with some environment variables that allows you to change its properties while running. Most of those property have a proton equivalent that will take precedence over protonlaunch ones for compatibility reasons.
Environment Variable | Description | Default Value | Proton equivalent |
---|---|---|---|
PROTONPREFIX | The path of proton prefix that will be used | ${HOME}/.proton | STEAM_COMPAT_DATA_PATH |
PL_STEAM_PATH | Path to your steam installation, used if your steam is not autodetected | autodetected | STEAM_COMPAT_CLIENT_INSTALL_PATH |
PL_LIBRARY_PATH | List of steam library paths separated by comma (:) | autodetected | |
PL_PROTON_VERSION | Version of proton to be used | autodetected |
All this information is also available with protonlaunch --help
