Don't stretch the truth and give them an unrealistic idea.

There are games that don't work, Some due to draconian and oppressive DRM or invasive anti-cheat. Some don't work just because.

Generally, the ones that work dont just because will eventually become playable. I've had a few games I had to back burner for a while, but a few months later became perfectly playable with proton updates and such.

But on the flipside I have Day 1'd quite a few games, some perfectly (Mostly games with older engines like Starfield), some not so perfectly (Like Cyberpunk 2077), but they were all very playable with patience and understanding.

@MrVilliam I suggest you hit protondb.com and check the games you commonly play. If they are gold or higher you should be good.

As for Distro, I'd personally recomend Nobara for gaming on Linux. Its a great experience, smooth, and has pretty much everything you need packaged in the install already, so you don't have to deal with any tedious bullshit like having to compile something if its not packaged for your distro.

I dont mean to repeat myself, but patience and understanding is going to be key in successfully getting it going. You're gonna be learning a completely new OS, and new procedures, from scratch. There will be moments where it may be frustrating trying to figure things out, but you don't have to be a Tech Savant to get through it, and once you get your head wrapped around it.. installing and playing will pretty much be as seamless as you're used to on windows. Its not perfect by any means, regardless of what anyone says, but its pretty god damn good where its at now, and is rapidly getting better.
