I’ve been linux exclusive since 2006, dual booted before.
Linux plays almost everything perfectly now except those with the nasty kernel-virus-style-drm stuff (which is surprisingly rare, most DRM’s work fine, it’s just those few garbage ones, and I won’t support companies that use that garbage anyway even if I were using windows), and it especially plays older stuff better than windows itself does, by a large margin in surprisingly many cases.
But just get a Steamdeck, lol, you can hook it up to a monitor and all and use it like a desktop, but it’s all set up and optimized for linux gaming already.
