I doubt you’re going to get many responses here that aren’t basically ” you don’t need Windows at all, proton is magic that will solve all of your problems"

I’m going to give the opposite advice. I can tell you from experience, if you dual boot Windows and Linux, you’re going to find that over time, while in Windows to use the stuff that only works there, you’ll ask yourself “do I really need to shut down Windows and boot into Linux just for that one thing I need to use real quick?”, and you’ll just do it in Windows. You’ll do that more and more, until you realize you have that Linux install sitting on your drive for no reason, because you don’t use it.

My advice is to either test out a gaming-centric Linux distro, and see if EVERYTHING you want to use works fully(and I do mean try it for yourself, doubt just assume it works because other people say it does, Google a setup guide for the thing you want, and actually try it), or if you have anything you want to use that MUST run on Windows, just stick to Windows for the time being. You can always keep an eye on the status of the thing you want to run, and when it works properly on Linux, have another look at switching fully.

One exception would be if you really only spend a very small amount of time gaming, and so would only need to be in Windows occasionally. If you really will spend the vast majority of your time in Linux, then it makes sense to dual boot. But if you plan to spend any real amount of time doing stuff in Windows, you’re going to find it really obnoxious to have to go back and forth.
