It’s been drop dead easy for me too in the past few years. Almost all of my gaming is through Steam and the Proton mode is like, a few extra clicks. It’s gotten to the point that I don’t even need to consult ProtonDB for runtime options now.
For old games there’s Lutris and its install scripts are a fuckton easier than trying to manually wrangle shit together (no matter what OS you’re on) which is even better
In fact, my completely non technical (and, notably, non programmer) friend noticed what my experience is like and as a result decided to dual boot on his new gaming rig. Mind blown. I didn’t even do any evangelising or shilling, I guess the best evangelism is just practicing what you (would) preach
I think dual GPU situations like laptops are sometimes a bit of a pain in the ass though from what I read.
I’m using a GTX 1080 Ti and nvidia’s legendary fuckery hasn’t impacted me
