Gentlemen, just for context, I usually use Linux. I have been a user of Debian, Ubuntu, and Fedora for a few years.
Recently, I acquired a decent graphics card (GeForce RTX 4070) and decided to uninstall my Windows and install Linux.
I saw that Pop!_OS already has an image with everything pre-configured for Nvidia. Is this pre-configuration worth it, are the games more stable on this distribution, or is it the same as manually installing Nvidia’s proprietary drivers on Manjaro?
I would recommend staying away from Manjaro regardless of your distribution preferences, for a whole range of reasons, some of which are documented here.
When it comes to Nvidia, don’t let people make it look like it’s some kind of an adventure quest with no map markers. Practically any reasonably maintained popular distribution will either have everything installed already, or will give you an Nvidia option during installation. There are still some long-standing issues, but the vast majority of them are either actively being worked on, or just got upstreamed, and it’s up to your distribution to deliver the update.
If you like Debian/Ubuntu based choices, Pop is not my preference, but it is a good distribution. Otherwise, Endeavour has been absolutely excellent. Fedora isn’t necessarily a bad option, but their package management policies will make setting up gaming workflows a pain. Nobara comes with all of that pre-configured, but is otherwise just regular Fedora
