Oddly it’s GOG games that gave me the most trouble. Steam has gone seamlessly with just a right click to select proton in compatibility for each game.
Lutris & Wine handled GOG.
Next up is seeing if ME Legendary and AC Odyssey will fxn.
But yes, I just had a conversation with someone last week. He bought a new Windows 11 laptop because his favorite games wouldn’t work when flipped his old one over to Linux.
