I've used my DS4 v2 extensively the past year. I can say that for the most part, it is a great PC controller.

Windows 10 installs appropriate drivers for the controller, and some games even natively support the controller out of the box. Though, a lot don't. For these games, you have to emulate an Xinput controller (Xbox controller). You can do this from within Steam, or by using third party software like DS4Windows.

Now, even then it's not perfect however. I have found that in Fallout 4 it is literally impossible to get a PS4 controller to work perfectly. It constantly reads wrong inputs and sometimes double inputs. Even when emulating an Xbox controller.

That said though, when it does work it is the best PC controller you can use. I can't even begin to explain how much I despise the LB/RB buttons on Xbox 360 and Xbox One controllers compared to L1/R1.
