This article is terribly misleading. Attempting to use the DS4 in Windows with Bluetooth is an actual, neverending nightmare. At all times. It's so annoying and preposterously difficult to work with, it's transparently obvious the author tried it just once, paired it, then called it good.
The DS4 is my favorite (and the best) controller but using it wireless is simply not feasible in Win10 or Win7. It's obscenely finicky, with DS4Windows or SCPToolkit. I've been trying for years, even tried four different Bluetooth dongles. It's preposterous that Sony didn't just PONY up and make this a reality. They'd have sold far, far more controllers.
