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.
Gaming with Wine was decidedly far worse before Valve started pumping money into it. Back before Proton was officially announced, there was a silent acceleration in Wine compatibility, getting better a rate we weren’t used to, and it’s in large part due to Valve partnering with CodeWeavers.
