Hello @EliteAMDGamer, my understanding is that support for running games with Proton is unofficial and unofficial options can't be enabled by default. The feature request at #7234 is a plausible way forward.
Closing in favor of the older feature request.
Since theirs no real reason why after all this time the user has to go into settings to enable proton manually. It would be nice if packagers could set a flag so its already on. Because users new to linux never know how to get games to work and its unlikely they have a large linux only game library.
They just get a gray button and don't know how to fix it causing issue tickets. So can we please get is in some way.
