For many games this script is not needed anymore, and may soon not be needed at all.
I would reccommend trying games with latest Proton Experimental, Proton-GE, or Proton-tkg first, and only using this as a backup. mf-install may not work with newer Proton versions that implement Valve's ongoing attempt to remotely transcode videos to free formats on their servers.
Easily add Media Foundation support to a Wine prefix. Just set WINEPREFIX to a valid Wine prefix and run.
Example usage:
WINEPREFIX="/home/user/wine prefixes can be anywhere/folder" ./mf-install.sh
Steam stores Proton Wine prefixes as <STEAM FOLDER>/steamapps/compatdata/<GAME ID>/pfx
Set the PROTON env variable a Proton folder, and pass -proton to the script. Example:
WINEPREFIX="/steam folder/steamapps/compatdata/111111/pfx" PROTON="/steam folder/steamapps/common/Proton 5.0" ./mf-install.sh -proton
