Steam on Linux has proton built in. It works smoothly with 90% of windows games, smoothly enough using tweaks with like 9%, and the other 1% have kernel anticheats.I'm not sure what distro you use, but I daily drive Ubuntu and proton hasnt failed me yet. (If you don;t know how to use it, just google steam proton linux, you'll find something, and protondb.com is a great tool for checking what games work and don't work)
