You will get there(although I haven’t heard great things about Fedora gaming). I made the switch November 2021 and I haven’t booted back into windows in about 9 months. I ended up picked EndeavourOS cause I wanted something Arch based to be as close to Steam Deck packages as possible(and I already prefer KDE Plasma, so picked that as well).
I still have my hiccups. I still can’t get SteamVR to work at all. I spent about 45 minutes yesterday troubleshooting why Outward stopped working, when all the protondb reviews say “it just works”. I did eventually get it working from a random suggestion from the arch forums to add PROTON_NO_FSYNC=1 %command% to the steam launch commands and that fixed it. If I had to guess I think it’s something to do with my 1070Ti not playing nicely with the latest nvidia drivers. Also Epic made some sort of stupid update to FallGuys and I can no longer get it working for more one initial run per install. So that’s frustrating.
But I also love how much I know my system now. I love being able to update everything from one or two commands. I love pipewire for doing music recording stuff.(I fought for years on windows to try and cobble together something similar). I love having bash macros to easily download embedded videos and do quick ffmpeg conversions. Really, it definitely comes down to how I feel much more connected to this system than I ever did to a windows install.
