OPTION 1: CONNECTION WITH A SONY WIRELESS ADAPTER
The simplest and fastest way to get your PC and DualShock 4 controllers talking to each other is with Sony's official wireless adapter ($ 25). It is a fairly inexpensive device, which connects directly to a standard USB port on your PC to work:
Step 1: Connect the adapter to your PC.
Step 2: Turn on your DualShock 4 controller, and both devices will automatically detect each other.
And that's it! It is definitely the easiest solution. Also, keep in mind that the adapter measures about 3 inches long, which means it will stick out of your PC or laptop like a flash drive ... something big, yes. Fortunately, you have other options.
OPTION 2: CONNECTING WITH STEAM
Steam, the most popular PC gaming portal in the world, offers native driver support for DualShock 4. It's incredibly easy to use your DualShock 4 to play on Steam: all you have to do is:
Step 1: Make sure your Steam account is up to date.
Step 2: Just connect your controller to your PC.
And ready! Well, almost ... Even if Steam is up to date, you might find some hiccups while setting up your controller. Steam is compatible with DS4 as a platform, but that does not mean that all PC games work with the controller automatically. If you turn on Dark Souls III, you'll see what we mean. Steam detects the controller, but Dark Souls III does not. If you find yourself in this situation, or just want to use your controller wirelessly without using Steam, you are not in luck.
DS4Windows could then be the solution.
