I use a Fedora variant called Nobara with my 4080. Driver management has been great.

I’m mostly a newbie to Linux, I’ve been using it as a main gaming rig for several months and only Nobara. I hear often that AMD is hassle free, but I’m using Nvidia and honestly I’ve had no roadblocks. I started with a 2080ti and have since moved to a 4080, no hassles. There is a built in updater and it automatically downloads the newest driver packages. They are always a version or so behind the latest Windows set but meh. Switching on gSync was as simple as toggling VRR for my 144hz monitor.

The one thing that I needed to look up was getting ray tracing running. There was additional stuff I needed to add in Steam (copy paste from the post I found), and then RTX was up and running.

Like I say, I definitely don’t know better than the people saying AMD is a smart choice, but I don’t think people necessarily need to worry that their Nvidia system is a roadblock to switching to Linux.
