No worries :) everyone starts somewhere.

The other commenter covered the terminology so to your point about being on Nvidia:

I know we don’t like Reddit but here. Seems to be YMMV and you’ll never know if you don’t try. Also possible that the things that are buggy aren’t things you use/care about

FWIW I run Ubuntu and do some gaming. Haven’t hit any issues, and I’ve run multiple AAA games on release (TLOU, Indiana Jones, Hogwarts Legacy, GoW 2018) as well as other, lighter, titles like Cities Skylines 2, Asetto Corsa, Project Cars, American Truck Simulator

I’m sure there are bugs that I haven’t experienced, and my system is probably newer/higher performance than the average person + i chose parts with Linux in mind. But based on my experience, I wouldn’t tell someone to jump into a less user friendly distro because of problems I myself haven’t run into. Much better to try one, see if you hit an issue, then jump rather than doing the hard one up front

Consider your library: most games will be able to run fine on Linux. However, if you predominantly play online multiplayer games which require anticheat you should check compatibility on ProtonDB.

Second, consider your hardware: if your GPU is AMD you’re good to go. Nvidia might have issues (not sure if this has been resolved since I last had to look into it).

Finally, choose a distro: I’d recommend Ubuntu or anything Ubuntu-based. There’s a lot of mixed answers in the Linux community and definitely a ton of hate for Ubuntu. However, as someone who has been running Linux for nearly a decade at this point, there are a few key points:

1. Ubuntu is debian based, so it’s extremely stable(but not as slow to update)

2. Ubuntu is very beginner friendly, and you won’t need to touch the terminal if you don’t want to

3. Everyone hates on snaps, but for you I don’t think you’ll run into an issue with it.

Personally, I steer towards debian based distros for my devices as well because I’d rather spend time messing with the software I’m running or other things NOT debugging why my config is suddenly shitting the bed
