Since proton/wine is unreliable in time, this is a disaster.

And there is a lot of BS around that: if some devs support their game on elf/linux via proton, they will have to QA it on a linux system anyway, so it does not change that much, even less with a game engine which has everything linux already... it only add the ultra-heavy-complex and then bug inducing proton/wine layer... an horrible mess to debug. One unfortunate patch, proton/wine side or game side, and compat is gone, and you are toast... and those patches do happen.

Conclusion: the only sane way is PROTON = 0 BUCKS.

I play only F2P games with proton (mostly gachas), no way I'll pay bucks for a game without technical support.

Valve should allow to pay games _only_ for the games with official elf/linux/proton support (aka the game devs do QA on elf/linux with valve proton... which would be no better than stupid if their game engine has elf/linux support already in). Why not let elf/linux users play all games which do not have official elf/linux support for free, well, those which run, and run decently, and until an unfortunate patch...
