WHAT DOES THIS MEAN FOR OTHER LAUNCHERS (lutris/bottles/heroic/legendary,etc):

  • everyone can use + contribute to the same protonfixes, no more managing individual install scripts per launcher
  • everyone can run their games through proton just like a native steam game
  • no steam or steam binaries required
  • a unified online database of game fixes (protonfixes)

    Its basically bugfixes for specific games through proton. Different fames need different fixes, so you cant just make a general fix for some bugs if they only exist in one game. The new launcher promises to make one database for those fixes where all the launchers can fetch their data from instead of everyone having to do their own thing and having to fix each game separately.
