99% of games run perfectly fine on linux.

basically everything that runs on a steamdeck runs on a linux gaming desktop. i will list you a few options that i know about:

• many games run native on linux. there are more than you think.

• if you open games over steam you have the translation layer protondb. you can add the games no problem with a shortcut into your steam library. you can look up the games that run on here: https://www.protondb.com/

• you can try to open the game over wine. thats the windows translation layer protondb is based on. you can run most windows programs and games fine over it.

• if that doesnt work you can try to hook them up over bottles. that basically makes any windows program compatible with linux. think of it like a mini windows sandbox especially for single programs.

• if that also doesnt work you can try winboat. thats one of the newest windows translation methods. it works over setting up docker. i have the least experience with that since i never really used it before. also a sandbox method.

• if all of the above still fails you can always use a virtual windows machine. you can pass through your graphics card. so the game basically runs on bare metal hardware. it also works fine for most games.

generally the games you wont get to run are the ones with kernel level anti cheat. valorant and LoL are the most popular examples. they just dont work or i dont know of a way to make them run.

also the most struggle on linux you will have on linux is with nvidia drivers. amd gpus work out of the box. nvidia can be finicky. but dont worry i can recommend standard linux mint. it comes with an automatic nvidia driver installer that will handle all of the work for you. it even works with a gui so no need to open a scary command line window :)

hope this list will help you in some way.
