And also, what distro might be best for me?
- For gaming and if you just want things to work without being bothered, Nobara. It's a Fedora base, which is good for gaming because you will have updates more quickly than other distros, but not so quick that you will get bad updates breaking stuff. It's Fedora but heavily modified for gaming, and has a lot of stuff already set up that you would need to do manually to improve gaming on another distro. It uses KDE as a Desktop Environment which is pretty good and similar-looking to Windows (a task bar on the bottom, a start menu, a system tray, etc) and you can customize it extensively.
How does digital security work on Linux? Is it more vulnerable due to being open source? Is there integrated antivirus software, or will I have to source that myself? Antiwhat ? Just kidding.
- You're not installing softwares by running executables found on random websites, so you at least have less chances of accidentally installing malware that way (not saying that happened to me a lot on Windows... but not saying that it didn't 😅 ).
- The best known antivirus on linux is clamAV, but it's command line only. It's not very complicated to use, but if you want a graphical interface there are several applications that are clamAV frontends (clamAV still does the actual scanning and such, but the application gives you a graphical interface to interact with it)
Will my ability to play games be significantly affected compared to Windows?
- For Steam games, the Steam app has Proton, which enables you to play Windows games on Linux, and most will work just fine. There will always be a few games that require tinkering, or that won't work at all, but not many. You can check ProtonDB to see if your games run well with Proton (https://www.protondb.com/ ) and if a game won't run, you can check it to see if people have posted solutions (sometimes it's as easy as copy-pasting a command into the game's launch options, and poof, there goes the DirectX error !
- For GoG games, and also games from other stores (EA, Epic, etc) you can install Lutris which will use Wine to make your non-Linux games work on linux. As will Proton, there will be a few games that won't cooperate. All in all, I'd say less than 5% of my games don't work or require tinkering, and I have a lot of them.
- If you play multiplayer online games that use kernel-level anticheats, you might be fucked (though I'd argue that it's a good thing, because the game not working is much preferable to the security risk posed by kernel-level anticheats...). Some games are still playable without the anti-cheat activated, you just can't join competitive servers without the anticheat, while other games won't work at all.
