After contemplating for 3-4 years about switching my main rig to Linux, I did it on Friday just gone.
Note for the below, I have a full AMD system.
I went with Garuda Dragonized distro as it is gaming focused and has all the game related stuff included.
took me less than 30mins going from gaming on Win11 to Linux, but I did the research before.
there are a few tweaks if you use Steam but you have Lutris to help you.
of the 35 ish games installed, all of them work without issues, but they need updating once you enable compatibility to Proton.
the default theme is too flashy but you can select to bring it down a few notches
Technical
if you have secondary SSD or HDD, dedicated to games or files like I did, it is advisable to have them backed up to an external drive as you will need to re-partition them from NTFS to use them properly in Linux
with Garuda Dragonized Gaming, all drivers are installed but follow the Wizard at the beginning and check all that apply to you. It will save you time.
Good luck and looking forward to having you on Linux!
