What OS is better for gaming?

Alright time to become a nerd.

We currently have 3 OS's to compete with gaming.
Windows, Mac, and Linux.

We can scratch Linux off the list since, lets be honest, Linux is basically for hosting, not for gaming. Even if you do game it wont support some.
Mac is made for workplaces, so that can get scratched off. Also Mac can't run .exe, you have to manually convert it using Wine or whatever its called.

I personally think Windows 10 is best for gaming, as its made for both work (Windows Server) and home ( Windows Home/Pro )
