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.
Proton is so good and has gotten incredibly mature. It’s the reason why I switched over to Linux full time, really. Haven’t looked back! :3
