This isn’t true and dismissing the anti-cheat issues because you don’t play these games is quite ignorant when they are some of the most played in the world. Just off the top of my head, all Battlefield games, PUBG, Apex Legends, Valorant, Rainbow Six Siege, Escape from Tarkov, League of Legends, Fortnite, Destiny 2…

I think it’s easily good enough for general use. It’s only certain types of gamers (anti-cheat support is still pretty terrible), and people who are heavily attached to a specific Windows program that they spend a lot of time using, that will have trouble switching across full time. For everyone else, Linux is superior because it runs so much faster than the now incredibly bloated Windows. Depending on the distro, it’s also arguably simpler than Windows too.
