Actually I play almost exclusively single player games myself, but even those games typically start with DRM protection that makes Linux difficult at times, Denuvo finally has their native support sorted without significant degradation of performance.

And as for the games you listed I would not say they work great on linux, they require tweaking, adjustments, driver updates, switching to experimental builds, etc..

I am not saying gaming isn't possible on linux, I'm saying it isn't as easy, and the results are not on par out of the box with windows. And the things you have to do getting it working are going to typically be provided by game developer support, but by community members figuring it out, and then that having to trickle out to forums and the like.

ProtonDB would typically agree, you can look at the games you listed and see that many of them require specific adjustments to get decent frame rates, avoiding lag spikes, etc...

Now, given the option of having a gaming partition that runs windows and is only used for gaming, or trying to force the games to work on linux. What do you think the majority of gamers would rather even those who are privacy minded.

I'm hoping in the next 5 years are so that this will change, and that windows looses its grip on this market, but currently I don't see many people switching their platforms over what windows is doing.
