When it comes to gaming on a Windows platform, two terms that are often thrown around are XInput and DirectInput. Both of these refer to the input systems used to interact with games, but there are some key differences between the two.

XInput is a newer input standard that was introduced with the release of Microsoft’s Xbox 360 gamepad. It’s a high-level API (application programming interface) that allows developers to easily integrate with Microsoft’s hardware and operating system. The Xbox 360 controller was the first gamepad to fully implement XInput, but many modern controllers are also compatible with the standard.

XInput provides a number of benefits when compared to previous input systems. It supports up to four controllers simultaneously, and offers improved precision and accuracy for gamepad inputs. It also includes features like vibration feedback and support for the Xbox Guide button, which allows players to access the Xbox dashboard or Steam Big Picture mode directly from their controller.

DirectInput, on the other hand, is an older input standard that’s been around since the days of Windows 95. It’s a lower-level API that provides more direct access to a controller’s hardware. This gives developers more control over their inputs, but can also make integration more complex.

DirectInput is still used in many older games and applications, as well as some modern games that weren’t designed with XInput in mind. It supports a wider range of input devices, including joysticks, gamepads, and racing wheels, but can be more difficult to set up and configure.

While XInput has largely replaced DirectInput in modern games, there are still some niche cases where DirectInput may be the better choice. For example, if you’re using a custom controller or input device that doesn’t conform to XInput standards, you may need to use DirectInput to get it working properly.
