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.
The famous bad flicker or ghosting of frames is a famous issue in Wayland caused by the desynchronization of frames. Around 2 years ago they patched the driver to let the system tell it explicitly how to sync the frames, and most Linux systems should have the drivers updated to work as such. Since them I've not had any flickering like that. A great example was Dragons Dogma 2, the flickering was insane but fixed by the patch.
I've been in Wayland since KDE 6.0 and I've a 3080. I think that's like 2 years now. And I game A LOT.
