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.
You’re massively simplifying it. Proton is a lot more than just “icing” on the top.
For those who don’t know such as myself, care to give more detail?
Check out this comment above for why it made such a huge difference.
