This way I was able to finally get rid of the pest called MS Windows
Install Pop!_OS on your gaming rig (a linux dist with some more recent hardware support incl. NVIDIA)
Then install STEAM on linux :)

Discussion
Will the games that are for windows only (on Steam) also be available for Linux?
I continued to play the same games on linux as the ones I played on windows.
Steam deck also runs on linux I believe, so they made quite an effort to support and run all games.
But DYOR and only switch once you tested it on your rig.
