'Similar support for other controller models is coming, but Valve isn't ready to announce any devices or dates for those just yet. Also, existing native support for the PS4 controller on the PC is a bit weak in this case Steam itself is communicating directly with the device so everything that's nice and reliable. 'Now, why start with the PS4 controller? Well, not only is it a really nice, high quality controller, but it's also got a gyro and a touchpad, so it's got a lot of overlapping functionality with the Steam Controller. You make the exact same API calls, you only get actions, not inputs, and the Steam API takes care of everything. 'Believe it or not, when you use the PS4 Controller through the Steam API, it's exactly the same as a Steam Controller. So always make sure to check beforehand and see if they can work with an external controller. I've only seen a few cases where the games even bothered to use the Sony style buttons, and even then most were from mods.Bellinghausen continued by saying the DualShock 4 is a great starting point as the controller's gyro and touchpad are very similar to the Steam Controller. Not all Steam games are compatible with a controller. In many cases that I used to see though, a game either had keyboard button prompts, Xbox 360 button prompts, or generic button prompts like it was a generic controller with 1, 2, 3, etc on the buttons. If the game supports DirectInput, you can turn off InputMapper and let Steam utilize the controller as a PS4 controller, and see if the game will give you the right buttons then. Any time a game gives you those buttons, it's 100% controlled by the game. Everyone uses those prompts because they just assume it's a 360 pad.

When Xinput came around big time for controllers on PC, was when the 360 controller was popular, and that's just stuck around. ALSO a simple mouse will not work either. The only controller they have is PS4, it works fine in the home place but when I open steam VR or a Steam VR game there is no white dot or anything and the controller gives no function.

DInput is older and less compatible now days. So I royally fucked up and forgot to pack my motion controllers when I left to visit my family for the weekend. The reason why the PC thinks it's a 360 controller, is because it's telling the PS4 controller to not be DirectInput and be Xinput, so everything can use it. Some games will allow you to change the buttons in their settings, or some games will even have mods to swap those out (Resident Evil 4 and Dark Souls come to mind).
