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.
Yeah, that’s not necessarily the case. Did it kind of work? Sure, if you knew what you were doing. Was it at all the seamless experience that Proton is now? No.
