It may be pretty good for previous-gen games and hardware, and that too after various compromises.

Current and next-gen PC hardware will always be optimized for Windows first, with some technologies being straight-up limited exclusively to Windows.

Not that gamers are losing out on anything valuable, of course. I run Debian stable and spend quite a few times gaming on it, and it turns out almost all the games that won't run on it aren't games worth playing altogether. But this is an opinion of the negligible minority like you and me. The Consumers will obviously care for the latest.

The only app still making me want Windows is Paint.Net. It really feels by far the best, if not say perfect, non-pro picture editor ever. I would even pay for really good (Pinta is quirky although indispensable) Linux and Mac ports. I also love Visual Studio but JetBrains Rider seems more than a match. Games indeed have ended being a problem long ago. Perhaps some latest and greatest games still are, I dunno. Have anybopdy tried something like Hogwarts Legacy or Baldurs Gate 3 on Linux?

I can too play a lot of games on Linux, just not all games that I want to play, yet at least

Which may be another motivation for them to buy up so much of the gaming industry. They can probably justify blanket banning anyone playing COD on Linux in the name of banning cheaters.
