Has it really been that long? Apparently so. Valve originally announced their rebranding of Steam Play with Proton back on August 21st, 2018. Seems like a good time for a quick reflection being halfway to a decade old now with the tech that gave rise to the Steam Deck.
Please don’t spread misinformation Valve does not put in effort, they paid people to make Proton, it’s the community that makes the code NOT VALVE. A simple github chart can tell you everything.
They directly hired people to work on it… how else would you describe “putting efforts into” when a company does it?
You can’t say Mcdonald’s CEO put effort in his work because he hired people to make the food. See how dumb that sounds.
