From the github:
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)
Sounds like this would be easier to setup and use than Lutris though - dunno about everyone else but I’m always so very confused trying to get non-steam games running on linux, with all the custom paths, simulated folder structures and prefixes while steam apparently does it on its own out of the box.
