Microsoft DirectX is a collection of APIs, also known as application programming interfaces. These interfaces are multimedia-related, and most frequently they are used for gaming and game development. By using DirectX, you get a high-level interface that allows you to access low-level functions directly. DirectX also accesses the hardware abstraction layer in Windows.

DirectX supports the following APIs:

  • Direct3D (D3D
  • DXGI
  • Direct2D:
  • DirectWrite
  • DirectCompute
  • DirectX Diagnostics (DxDiag)
  • DirectX Media Objects
  • XACT3
  • XAudio2
  • DirectX Raytracing (DXR)

DirectX provides the interface to access the advanced features of the graphics card and it allows you to emulate graphics functions in software using the Hardware Emulation Layer.
