Just install Linux? SteamOS is just a Linux distribution based on Arch. My current distro is Garuda, which is also Arch based and has a gaming focused version with everything you need for gaming pre-installed.
Linux is as plug and play as it gets now, if you choose the right distro. It's easier than Windows at the very least. Again, SteamOS is just a Linux distro.
If you want something, Garuda Dragonized comes with everything you need already installed and a GUI tool to quickly add anything extra you may want. It's as easy as it can be.
Also, I want to try to word this as politely as possible, but there are a lot of older people who continue learning new things. It's actually good for your brain health to do so. Refusing to learn something new isn't because of your age. It's a choice. You're free to make whatever choices you want though.
How is CS2 working on it? I know I could just try to get it running myself on a spare pc, but I find that as I get older I dislike fiddling with things like this more and more. And while I'm fine with just playing games made to work properly on Linux, CS2 and it's predecessors is something me and my real life friends have been playing for nearly two decades. It's a way to keep in touch as everyone has kids and can't come to the pub during the weekend.
Haven't tried that distro specifically, but I have been gaming on Linux for at least 4 years now and Counter Strike is not a problem at all. It is my most played game and it works great for me on Linux mint.
I imagine running it on a distro that has a focus on gaming will only make it run even better and easier.
@hanke@DV8 Valve is highly unlikely to put a kernel-level anticheat that bans Linux users but as a piece of advice, don't run competitive multiplayer games on Linux, I mean do not get accustomed to, that also should apply to me since I play Palworld which is MP only, even on SP, you can have someone join at any time
I would recommend anyone to play competitive multiplayer games on Linux.
Competitive games, and specifically CS, has been my go-to for about 10 years (I am still shit tho). As you say, Valve will most likely not put anti-cheat that won't work on Linux in it. But if they would do that, I would just not be playing CS anymore.
I play what I like, and if they would make the stupid choice to break it for my machine I guess they just don't want me playing it any more. In that event, I guess I'll just have to find something else to play.
