A lot of Linux ports have serious issues, it's quite common to get better performance/fewer bugs by forcing a Linux native steam game to run the windows version through Proton instead.

Realistically a lot of devs aren't going to make Linux versions at all (or be able to spend time actually fixing issues with them) unless Linux users make up a bigger market share. Valve's efforts are helping to grow Linux market share, which is a necessary step before we can ever hope for most devs to focus on Linux compatibility.
