I feel like this is a question that might have been asked around and maybe there are guides around, but that's a discussion that I'd like to have with the lot of you.
The context
Using Linux on both my work laptop and the Steam Deck has made me quite interested in a full switch to Linux - my other computer is a gaming desktop, which I use a lot for many things, but mostly for gaming. Getting used to Linux has made me quite more intolerant to all the BS Microsoft is pushing than I used to be, the latest one being forcing the users to switch from the older email client to the new Outlook, which has a big, nice ad banner that looks like an unread email. So I've began wondering: after all, why not? Why shouldn't I embrace the penguin? Well, the answer is that I should not if there are too many hinders and drawbacks in using Linux, which would make me need a dual boot instead of a single OS install.
We all know gaming has long been one of the main limiting factors in switching, but the Deck has changed the whole landscape on that front. We've basically switched from "Windows is the only OS suitable for gaming" to "Linux is also viable", and the Deck has been made that available to the general audience. Therefore, nowadays, how viable is Linux for a gaming computer? What are the limitations users will encounter? Would I be able to play all the games from my Steam, Epic and GOG library with a bit of tinkering, including the new releases?
The drawbacks of using Linux (or those that I can think of)
- Other gaming launchers support on Linux suck: GOG and Epic will work through Heroic Games but Activision/Blizzard, Ubisoft, EA and Rockstar games will all be a pain, or even not work at all. Is is true? Is there any way around that?
- No Microsoft GamePass. Or none that actually matters, as the only solution is to pay for the higher tier and stream the games - so no game actually runs on the desktop. No, thanks.
- Some DRM will prevent games from working, and this is especially true for games with heavy online content.
- NVIDIA support for Linux is far from being on-par with that on Windows, especially the open-source drivers. Is this still true?
- Many devices, especially those for gaming, might not have good (or even working) compatibility drivers for Linux. I know my UWQHD monitor works flawlessly on Windows, but requires quite a bit of tinkering on Ubuntu
- Newer games might not be optimized for Linux in the first place
- Tinkering is inevitable (as with any Linux computer, really)
What can we add?
The advantages (I can think of)
- It's free
- It's ad free
- Customization on Linux is awesome, and I might end up spending more time ricing, breaking it all and reinstalling than gaming (see also, previous section's 7.)
- I will no longer be sending data to Microsoft
What else am I not thinking about?
What distro?
And finally, let's say I make the switch. What Linux distro should I use? I've read a bit about Drauger, Ubuntu GamePack, or even Pop! OS with some manual setup. What do you guys think, and advise?
For the drawbacks:
To be fair, I'm coming at this from the perspective of a patient gamer. I generally play older SP games (rarely play MP), wait to upgrade hardware (recently bought a 5600 and 6650XT to upgrade my 1700 and 960GTX), and am pretty technically inclined (I'm a SW dev by day, and have used Linux exclusively for ~15 years).
For me, Windows is unacceptable, and macOS is too limiting for hardware choices (and I just don't like it; I've used macOS at work for 2 years and still dislike it).
So instead of discussing native advantages of Linux, I'll list things I'm glad I don't have to deal with on Windows:
For me, Linux solves my non-gaming problems much better than Windows, and I fundamentally disagree with how Windows works so I refuse to use it for gaming. But even for people who aren't like me, Linux is a pretty good option with few downsides, provided you don't need something specific to run (e.g. that one MP game you play all the time). If you can be a little flexible, Linux offers a ton of choice and even more freedom.
Edit: As for distro, just try stuff. I think Mint is decent, so I tend to recommend it, but I use OpenSUSE Tumbleweed myself (also recommended). There's not a ton of difference when it comes to running games for most distros, so pick one that seems to have decent community support and have fun! You can always change later, I've used several (Ubuntu, Fedora, Arch, OpenSUSE Leap, Debian, probably others).
