I'll happily switch to Linux on the day when every new release works with no extra problems, tinkering, waiting or searching caused by my choice of OS.

Let me give you an honest answer that no Linux users is willing to give you (certainly because they fear to scare people off of Linux): you will never see the day where Linux will be equal if not better than Windows for gaming (which it can be sometimes, but it's not always the case) if not a certain amount of people get out of their comfort zone and are willing to try something new. In fact, nobody can improve anything in their life if they're not willing to get out of their comfort zone.

You're already using a PC to play video games, I did this choice too, so trust me, you definitely have the energy to change for a better OS, something ever you recognize as having qualities outside of games. Otherwise, you would've played exclusively on console where you actually have a plug and play experience... unfortunately at the cost of your freedom to use the machine you bought however you want, besides all the other considerable disadvantages.

For me, Linux made as much progress as it can do, meaning now, for Linux to be viable for gaming, either companies start to move their asses and make Linux native games (which they can easily do, if they're willing to use the right tools for their game like Vulkan) but I hardly see that coming any time soon, or new users have to come to Linux so that companies would finally care. Personally, I made my choice by making the first step.
