I've tried three times to fully convert my gaming rig to Linux, sticking with the effort at least 3 solid months minimum each time. The first time was back in 2015. Only a small subset of my Steam Library worked, despite all of my best efforts hacking on bottles, and there was no way I could stick with it if I intended to play anything with friends. Community aside, Valve and Feral were leading the charge, but I could not stick with it.
My second attempt was around 2019. Almost half my library ran, some in need of care and feeding, others barely functional, but running nonetheless. This was primarily due to my curation efforts of trying to make sure the games I bought offered some slim hope of compatibility. Wine was still a very inexact science, so attempts to get things running outside of native ports or Valve games was a poor facsimile. WineDB representation of compatibility layers was a wide gradient of colors, with most AAA titles still squarely in silver territory or worse. Anything with anti-cheat was a fool's errand.
My rig's now been on Linux for 4 months solid, and the state of Linux gaming is nothing close to what it used to be. The state of EAC support thanks to Steam Deck represents a quantum leap all its own, and that wouldn't have happened without Proton. The overwhelming majority of my Steam Library runs with no effort, each game running nearly as good or better than it did on Windows. This shift did not feel incremental.
