I still see people asking which distro to use, is it ok if they have an Nvidia card? How ready is Linux for a gamer? I have been 8 months now on Linux, it's about this hard to have an Nvidia card: click update. The way I switched was to populate the second m.2 slot on my MB and install Linux there, I chose Nobara, that way I had the fallback of Windows 10 if I had issues. Well, I still have Windows 10, it exists as a console with no internet access, it runs my Skyrim setup with it's 982 mods that I can't be arsed to move. Everything else is on Linux, it's the default and daily driver. Look close, you can see my system automatically updating OpenMW for me, quietly supporting my 260+ mod remaster of Morrowind. If you're wondering whether Linux is ready for gaming, yea, it is. Give it a try.
I have an nVidia RTX 3060, running on a desktop I built back in 2009. I'm running Linux Mint with the KDE Plasma desktop with no problems. All the Steam I bought on Windows, run with no problems under Linux.
Any non-Steam games, like Giants: Citizen Kabuto or Deus Ex (1) run on Wine under the default settings with no problems.
