# System-wide Wine for Steam client (Proton/Steam Play) games with system-wide DXVK & D9VK support
#
# Put this file into
# $HOME/.local/share/Steam/steamapps/common/Proton <version>/
#
# Select this specific Proton version in Steam client configuration menu
# (Steam Client -> Settings -> Steam Play).
# This means system-wide Wine, DXVK & D9VK are used for your Steam Play games.
