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?
As others have mentioned, many multiplayer games have anti-cheat, which is more likely not to work in Proton than it is. This area may continue to improve. See http://areweanticheatyet.com
Personally, I play a lot of Japanese visual novels, which usually aren't released on Steam. Games encumbered with PlayDRM from DLsite will work in Wine, but all games from DMM are encumbered with DRM that doesn't work in Wine. Wine is a compatibility layer for Windows games that makes them work on GNU/Linux, in case you weren't aware.
On the other hand, many physical releases of visual novels aren't encumbered with DRM, so they work fine in Wine. AlphaROM can be worked around by inputting your serial key into the SETTEC website.

This is usually not true. There aren't many native GNU/Linux games today; most of them are played using Proton, Steam's compatibility layer for Windows games. There is no inherent penalty in translating Direct3D calls to Vulkan calls. Vulkan has the potential to be faster than Direct3D, actually. Native games may not be as optimized as the Windows counterpart, but as most of these are small indie games, performance is usually not an issue anyway.
It's a good idea to use a rolling release distribution. This is mostly to get the latest drivers; Steam and Lutris both ship a runtime with most of the dependencies you need to play games otherwise, though installing Wine on Ubuntu and Debian is harder, for example. Fedora and openSUSE are good choices. openSUSE in particular has robust graphical tools for package management and other activities which other distributions might force you to use the command line for.
I think a rolling release distribution is a good choice for a general desktop anyway. You're running the latest software, which means the latest bug fixes and security fixes.
Thanks to the success of the SD, I believe many developers have started testing and optimizing their games for Proton, which I also account for when I'm talking about "optimized for Linux".
Noted for the rolling releases! Don't rolling releases necessarily bring the risk of unstabilities as well? There's often a balance which might be hard to find between features and stability.
@hydroel @Spectacle8011 I've not necessarily seen anything truly world-ending when it comes to bugs in any Linux distro I've run. There'll always be quirks and such somewhere, but I run Fedora and Gentoo on my boxes at home, and neither one has issues running games (other than the Fedora machine being a tablet, and not really being my main gaming machine).
My spouse who runs Windows has about the same number of games crashing out as I do, FWIW
The Steam and Lutris Runtimes do a good job of ensuring a good experience on most distributions. The only things that can really screw you up are graphics drivers and really low-level dependencies, like glibc. You're more likely to have issues with Wine, DXVK, and those components than the distribution's packages.
