Recent testing revealed that Arch Linux, Pop!_OS, and even Nobara Linux, which is maintained by a single developer, all outstripped Windows for the performance crown on Windows-native games. The testing was run at the high-end of quality settings, and Valve's Proton was used to run Windows games on Linux.
Since Steam stops working on Win7 in january I was forced to update the OS and I went with Ubuntu since the newer windows seem like plain garbage and spyware. Installing the OS was a huge hassle and getting DayZ to run on it wasn’t without an issue either but it works now and the performance seems to be about the same. I only use the Linux machine for occasional gaming so it’ll do but I’m not sure if I could daily drive it. Everything seems to need you to do something in terminal which I understand nothing about and aren’t interested in learning.
You may be more interested in the Steam Deck, a ready-to-go Linux gaming system that doesn’t require terminal proficiency. Just turn it on and play like a Nintendo Switch.
I don’t feel like buying yet another device when I already have a decent gaming rig. I’ve got a PS4 too but I never use it because I prefer using a mouse and keyboard.
