I still see people asking which distro to use, is it ok if they have an Nvidia card? How ready is Linux for a gamer? I have been 8 months now on Linux, it's about this hard to have an Nvidia card: click update. The way I switched was to populate the second m.2 slot on my MB and install Linux there, I chose Nobara, that way I had the fallback of Windows 10 if I had issues. Well, I still have Windows 10, it exists as a console with no internet access, it runs my Skyrim setup with it's 982 mods that I can't be arsed to move. Everything else is on Linux, it's the default and daily driver. Look close, you can see my system automatically updating OpenMW for me, quietly supporting my 260+ mod remaster of Morrowind. If you're wondering whether Linux is ready for gaming, yea, it is. Give it a try.
Nvidia is FINE on Linux. There's just a couple extra steps.
All of these Nvidia GPUs being bought for all this AI bullshit? Running Linux. Every stupid AI company runs Nvidia right now, and it's on Linux, so don't worry.
Pick a mainstream distro, lookup the steps for installing the drivers and blacklisting the Nouveau drivers which sometimes take first dibs, and you're golden. Few commands at best.
AMD is just simpler because you don't have to manage the drivers, but it's really not a big deal. It's very easily handled.
I had to fiddle with it for a while when I moved my main machine over to Linux a few months ago, but that's mostly on me because I chose Arch & Hyprland.
If I had gone with a mainstream distro with a "nvidia" variant, it would have likely just worked out of the gate.
Hell, if you had gone from an arch derived distro like EndeavourOS and just clicked the nvidia option. It would have been solved.
Not with Hyprland, I had to set a nice chunk of variables to make it work properly.
