Yes and no. I play singleplayer and indie games, but I also play competetive online multiplayer, but that’s mostly one game: Predecessor. It uses EasyAntiCheat and also just works. The games you play you can just look up if they work, usually it’ll be a yes/no and not more complicated and that mostly depends on the dev. Like Predecessor, where they ticked the box in EAC so it’s just fine. The number of games that do not work (specifically due to anti-cheat) isn’t huge, and well-known to check. You can just look up if it’s just a game or two you occasionally play, or if all you play is on that list (for a quick glance, check ProtonDB).
You can also just try to switch, if you actually want to, and only go back to Windows for the few games that need it. Maybe you’ll switch back and forth for a long time. Maybe you’ll find it’s too much effort to switch back to Windows and you play something that “just works” on Linux. Or you’ll find the switching annoying and you’ll keep booting mostly to windows “just in case” you wanna play one of the games that need it. Trying it out is very little effort and time these days.
In just over a year the only thing that ever broke was a minor thing (probably a bug in KDE that slipped through) with no practical impact and an easy workaround, which then got fixed in like 3 days or something without any intervention from me. I’ve had more (in numbers) and more severe breaks in the same time frame on a server at work that’s running debian, one of which was related to actually booting the server.
The whole “rolling releases are so unstable” mantra gets thrown around a lot, and it almost stopped me from trying CachyOS/Arch when I switched. My personal experience has been the complete opposite. I honestly can’t tell if people who never tried these distros just keep repeating what they heard or read somewhere, or if I really am just pretty lucky.
I love that I don’t have to worry about getting some semi-modern software to run, like I’m often worried when on a debian based server and have to manually install so much shit by hand that I’m losing track, which I then manually have to update in the future. On CachyOS, I just assume whatever I can install is the latest version (it usually is, only once was it not I did took a minute to figure that out as I just dind’t expect it anymore). And usually I can just install whatever I’m looking for.
Another note: I’m running CachyOS on both my desktop and my laptop. My desktop I use daily, and I usually even update daily (it’s just the way I’m wired, and I don’t mind). My laptop I use rarely and consequently I only update it every few months or at least weeks. Neither approach has caused any issues. But do not assume that your install can’t break either, things can go wrong (as they can on Windows). But support for even relatively specific problems is reasonably easy to come by, and people are generally helpful (discord, forum, …).
