Not yet, in order to be ready for mainstream gaming, the gaming experience has to be smooth (As in easy to install, Mod & patch)

Considering a majority of people use Nvidia on their desktops, they'll be forced to jump through hoops with stuff as minor as setting their desktop session to X instead of Wayland (which is absolutely not ready) to installing a custom vaapi package to get hardware accelerated video playback in Firefox. With games and Nvidia say goodbye to a chunk of DX12 performance Then you have the majority of laptop users that have intel HD graphics laptops, ones made in the past 10 years will be fine for low end stuff, but they will take a hit because i915 shits itself with DX12 games and the new xe driver that handles it better is very new and only available on iGPUs made in the last 3 years or so? It is really only good if you have an AMD GPU which has absolutely pitiful market share, with the Steam Deck probably being the most popular AMD PC device people own.
