ok so, im pretty sure i used “sudo pacman -S steam”
here are the commands you told me to do, (i have no idea how to read those but i think i have a Geforce GT 730)
I didnt really understand how to install proton-ge, i did the command but it didnt show on the steam compatibility tool, asides from all those tips, none of them worked
(btw im sorry if my english is bad, its not my first language)
