Finally got tired of my Windows 11 install, and I considered a Linux move. For years and years, I tried to move over, even all the way back in the Ubuntu 16.04 days, even daily drove for a few months, but there would always be something that would make me move back (including but not limited to HDR, support for my old iPod, Outlook calendars, so on). However, on my most recent attempt (running Arch and KDE) things just… work? Yeah, some command line trickery is needed for stuff like HDR gaming (and turns out the screenshots work now, they just get downsampled to SDR by Steam), but this works so so much better than my previous attempts to move over. In recent years, the experience is just so much more polished than it used to be. The situation is no longer “that won’t work”, it is “you can do that, with some minor tweaks”. All my Steam games work nearly perfectly, with only a few changes like Proton GE needed. There are now even improvements like how text on my QD-OLED monitor (which is notoriously fuzzy on Windows) is crisp and clear, or how my Xbox controller’s screenshot button works over Bluetooth on Steam unlike Windows which ignores the button entirely over Bluetooth. Things are really looking up!
If you aren’t trying to run anything too crazy (like AMD HIP compute, HDR, really bleeding edge hardware) I would probably recommend giving openSUSE Tumbleweed, Fedora (only the regular GNOME version, for some reason KDE spin was buggy in my experience), and Pop OS a test drive off live USB drives. Each has their own merits, so it’s worth trying all of them. In terms of NVIDIA support, I personally do not have much experience with NVIDIA cards, but when I was helping a friend format an iPod Fedora booted off a live USB on an RTX 4050 laptop with little fuss, and if you install it gives options for installing the full proprietary NVIDIA drivers. I know there is also an NVIDIA installer option in YaST’s software manager for openSUSE, and Pop even has an ISO with the drivers baked right in for full compatibility. However, your mileage may vary, although I have heard the whole NVIDIA situation is pretty good right now as long as you have the proprietary drivers installed.
