I recently switched from Windows 10 to Fedora so I can share my experience. I’ve dabbled with Linux in the past but there’s always been immediate issues which have caused me to never stay that long. It’s too easy to just ditch and go back when everything on Windows just works out of the box. I was getting sick of all the privacy issues so decided to totally bail and go balls deep. I found it easier to push through all the problems by adopting a mentality that I was living with this now and I eventually started to enjoy fixing all the problems (it took a few weeks). Everything’s working now and solutions are out there, you just need to google and power through.
Installing Steam and Nvidia drivers is easy. You open the settings of the “App Store” and enable third party repositories. Once you’ve done that the Nvidia drivers and Steam will turn up in there and can be installed with the click of a button.
However, and maybe I’m just unlucky, but the dream of Linux gaming has been an absolute non-starter for me. I guess people on Radeons may have more luck but with my 2060S I haven’t really gotten anything to play acceptably. Even with Proton-GE and whatever other hacks people talk about everything has been unstable, slow, or both, and that’s if it starts at all. I’m sure it’s probably just the certain games I’m trying to play but I ended up partitioning my drive and installing Windows 10 again just for gaming.
Something else to try is Nobara, it’s a Linux distro built for ease of use and gaming. If I’d heard of it earlier I’d probably have tried it first but I’ve got Fedora nicely set up and I don’t think it includes anything I can’t simply install myself.
