Introduction to DXGI
DXGI stands for DirectX Graphics Infrastructure, a set of application programming interfaces (APIs) developed by Microsoft. It is designed to provide a common framework for managing graphics resources, handling display output, and facilitating communication between graphics hardware and software components. The primary goal of DXGI is to enable developers to create high-performance, visually stunning graphics applications that can take full advantage of the capabilities of modern graphics processing units (GPUs).
History of DXGI
The DirectX Graphics Infrastructure was first introduced by Microsoft in 2006, as part of the Windows Vista operating system. At that time, the graphics landscape was dominated by the DirectX 9 API, which had been around since 2002. However, with the advent of Windows Vista and the introduction of the Windows Display Driver Model (WDDM), Microsoft recognized the need for a more modern and flexible graphics infrastructure. DXGI was designed to address the limitations of the older DirectX 9 API, providing a more efficient, scalable, and secure framework for graphics rendering.
