Well there is
- Vulkan (graphics API, successor to OpenGL which was used by e.g. Minecraft, CS Go i believe)
- DXVK (compatibility layer for games created with the DirectX Framework by MS)
- Lutris (game launcher for stuff you bought outside of steam, e.g. GOG, Epic, Uplay, etc.)
- Steam and maybe Proton but idk.
- the atom thing could be protondb.com, where you can look up if your game will run on linux and what fixes / commands are available
It surely is, it has also been really great to see the growing support for all those games over the last years. Sad to see some games still being borked with no valid reason (Pubg e.g., with the developers stating the game can run on linux with no problems at all, they still will block it bc they are scared of hackers or some other lame excuse).
Every problem I had playing games on Linux could be fixed by some kind stranger on there offering a command or sth. else (sometimes even stuff thats not related to linux at all lol)
There’s also a great decky plugin that adds protondb badges and links directly to all your games on the deck. Really helps figure out any small tweaks you should use to maximize frames and will also mark games as silver/gold/platinum even if valve hasn’t marked them as supported yet.
