If we limit the conversation to gaming specifically, one area where I don't see Linux taking over any time soon is competitive/esports oriented titles and their invasive ~rootkits~ anti-cheats. Another place I kind of have to live with Windows is simulation (in my case Elite: Dangerous and iRacing/Le Mans Ultimate) - the overlays and other third-party utilities either don't exist on Linux, or I couldn't get them to work and kind of abandoned the idea.
Audio production is also kind of a no-go. The DAWs and hardware support are absolutely getting there - Bitwig studio is apparently very good for something Ableton-like, and my DAW of choice, Reaper, has native Linux support. But the plugins and virtual instruments for the most part just don't exist. Some work through a Wine bridge, if you're lucky.
However, if you're not too deep in a niche with very specific pieces of software, or don't care about esports offerings, there isn't much tying one to Windows nowadays.
I always see this as a yes and no. Yes if you didn't start giving up on mainstream DRM encumbered audio production 10-15 years ago you aren't going to be ready to switch. Those people have sunk too much into their work flows and collections of licensed plugins.
No if like me you gave up on those tools and found new ones, because I didn't like the direction things were going with usb license keys, always online drm, and offline license management installs that feel almost as rootkit/malware coded as modern anticheat systems.
It helps that I gave up on ableton back in 2008 and swapped to Reason & Logic, before ultimately giving up on those as well. Now I just use Renoise & VCV Rack while trying to work up the will to dabble with Puredata and Supercollider.
Bitwig sounds nice but its too expensive and locks me back into the same cycles of update purchases Ableton & Reason once did.
Do I miss my Korg VSTs & Reason Racks? Yeah, I just can't be bothered enough to go back.
In the end for me its just a hobby so I've been willing to throw away my setup and workflow entirely more than once since starting with digital music in 2004.
- Bitwig 5.x (haven't tried the latest 6.x) is working really nicely for me now across several NixOS machines (I'm using BitwigBox so that yabridge smoothes out VST integration). - Le Mans Ultimate is working for me now. It would hang on loading a track until a month or two ago (GE Proton recommended).
What games are available? Do you use emulators or stuff like Wine?
This has made many old and modern games playable without issues. On Steam or Heroic Launcher, running a game has mostly become as simple clicking install and later play.
That being said, it's not all peachy. There's not really been much progress on native Linux gaming outside of Flatpak/Steam Linux runtime. Many native games run worse or with issues.
And Proton/Wine isn't perfect. Many games need tweaks or may not work without glitches. And games with anticheat don't work more often than they do, on purpose.
Still, depending on what games you play and hardware you own it has become entirely possible to ditch Windows and not suffer for it.
But I fully switched to Fedora a while ago because every game I played was either just as performant or ran better on Linux. It’s plug and play, too. I just downloaded Steam and that was it.
I know there are other commenters saying the same thing, but I’m just super excited because of what this means for Linux market share on consumer machines
as mentioned above if you play any competitive games that come with anti-cheat features, then you won't be able to join in the fun. So if you don't care about those games, you'll be fine.
I'd say it's a majority of games that won't work if they require anti-cheat, but some will.
Steam/Valve has built Proton, which I believe is a fork of Wine, and put significant resources into it. Steam distributes it on its own but CachyOS distributes even more patched/optimized versions of it in their repositories.
The games I know do NOT work on Linux are usually online multiplayer competitive games which have kernel-level anti-cheat. Notable for me is Fortnite - though I hear that now, there are even options for enabling strong anti-cheat in Linux but Epic chooses not to support it.
I'm not informed on other niche game types like simulators or games requiring special equipment, but chances are if it's not competitive, or it's single player, you can get it running with good performance on Linux with modern hardware.
