I use cachyos as my daily driver for a long time now. I play quite a few games. Only league of legends forces me to dual boot into windows every once in a week or so - fuck the anticheat cartel

I'm approaching a year now on CachyOS and it has been a wonderful experience. All the games that I play run just fine, maybe a few FPS drop compared to Windows, but it's not a big deal for me. I also don't play any competitive online games that require 3rd party anti-cheat spyware. Biggest positives, I got very comfortable with terminal and CLI work. My development work has definitely improved.
