Here's the thing... I have limited time for gaming and when I want to play I just want to sit down and play. My days of sodding about with (the equivalent of) autoexec.bat, config.sys, QEMM configurations, drivers and IRQ allocations are way way behind me for one when one of these combos of drivers and scripts doesn't work, or my game isn't supported, and I just want to spend a hour or two gaming to chill out.
Your comment describes the perpetual state of Linux desktop use in general. Every couple of years I check it out again because people on HN, Reddit, or some other forum *swear* that it "just works" now and you don't have to mess with config files, drivers, or spend hours researching some strange issue. After booting a Linux distro I learn that's still not true within 15 minutes or so, and go back to Windows.
All games I want to play these days work under Linux without effort. Older titles work even better where under Windows you could run into compatibility issues not so under Linux because of the great effort put on backward compatibility by Wine.
Also, a bit susprising and unfortunate, the Windows version of a game that has native Linux support often runs better.
I run Manjaro Linux and have an Nvidia GPU for if it matters. My Steam games I run with Steam and for the games I bought on GOG I use Lutris.
I would really suggest people to check out how far it has come.
I didn't even know about this when I installed steam on Linux in order to play two games. "Nice, they support linux" I thought. It wasn't until the third time that I understood that they were windows games supported by steam/wine
I think Manjaro is a great choice for gaming rigs. You get easy access to latest kernels and drivers without having to babysit your computer.
Only problem with Linux gaming is that you don't get stuff like fan, voltage, frequency control for newer AMD hardware. This hasn't been an issue for me until I got a 6800XT. I thought about RMA until I remembered their Adrenaline software exists. I wish I could save my settings to the card's BIOS.
I no longer use this machine for anything but gaming. Going back to windows sucks
They are not necessarily applicable to everyone, but most of the time they are accurate. Makes it easy to see whether setting it all up under Linux is worth it for your library.
