One main selling point of DS4Windows is its ability to use multiple different profiles, all of which can be set on the launch of a certain application. That means you could use one profile while running an indy on Steam while switching to a different one when you launch a flight simulator, for example.

Other options that DS4Windows includes are adjusting touch sensitivity, adding special actions or using macros.

Overall, if you're a gamer and like using your DualShock 4 controller while playing on your PC, DS4Windows is an excellent choice.
