and there was much rejoicing!

Gaming is the only reason I still bother to install windows on desktop PCs.

The topic of market share, and ports and lack of them, are nuanced but I highly doubt Linux won't overtake macOS even more each year unless Apple wakes up. Valve and Linux community are a force to be reckon with. There are other individuals in the scene as well, who are chipping away at improving the gaming ecosystem, such as System76, Redhat and Canonical.

I switched to Windows for gaming this year. With advances in Wine/Proton it was super easy; there's nothing I play that isn't perfectly convertible to Linux anymore.

Even using an Nvidia card in my desktop seems fine.
