• Set up the Steam environment.
• Use Proton-GE as the executor.

If you want to use Proton-GE, you need to set the following environment variables:

• STEAM_COMPAT_CLIENT_INSTALL_PATH=$HOME/.steam/steam
• STEAM_COMPAT_DATA_PATH=$HOME/.local/share/Steam/steamapps/compatdata

For optimal performance on an AMD card, add the following two environment variables:

• RADV_PERFTEST=gpl
• VK_ICDR_PATH=/usr/share/vulkan/icd.d/radeon_icd.x86_64.json

• -g, --game-path: Specify the path to the game installation directory. This argument is optional and defaults to the value of the DAD_PATH environment variable.
