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.
When I tried out fedora on my gaming PC I noticed most games ran noticeably worse on my Nvidia card. They still ran, you could still play, but the experience was nonetheless worse. Elden ring went from rarely dropping below 60 on windows to hovering around 45. FFXIV which would often be at 144fps, usually around 110 during dungeons and only dropping below 100 in really busy cities, went to never even reaching 100.
It's doable but be prepared for games to run worse. When I looked up issues I found this was normal for Nvidia cards. So just be prepared.
