The DirectX team faced the challenging task of testing each DirectX release against an array of computer hardware and software. A variety of different graphics cards, audio cards, motherboards, CPUs, input devices, games, and other multimedia applications were tested with each beta and final release.

DirectX Diagnostic Tool (DxDiag) is a diagnostics tool used to test DirectX functionality and troubleshoot video- or sound-related hardware problems. DirectX Diagnostic can save text files with the scan results.
DirectX version 3.0 (1996) added support for keyboards and mice; it also improved joystick support. DirectX 5.0 (1997) included greatly improved joystick support, including adding haptic feedback, increasing the number of buttons, changing the underlying device-driver model and incorporating a COM-based API. Mouse support also increased the ...
WARP is a full-featured Direct3D 10.1 renderer device with performance on par with current low-end graphics cards, such as Intel GMA 3000, [2] when running on multi-core CPUs. [3] To achieve this level of rendering performance, WARP employs advanced techniques such as just-in-time compilation to x86 machine code and support for advanced vector ...
It also supports new DXGI interfaces required for basic device management and creation. The WDDM specification requires at least Direct3D 9-capable video card and the display driver must implement the device driver interfaces for the Direct3D 9Ex runtime in order to run legacy Direct3D applications; it may optionally implement runtime ...
The Graphics Device Interface in the architecture of Windows NT For example GDK makes use of GDI. The Graphics Device Interface (GDI) is a legacy component of Microsoft Windows responsible for representing graphical objects and transmitting them to output devices such as monitors and printers. It was superseded by DirectDraw API and later ...
This device is used when the SDK is not installed and a reference device is requested. Pluggable software device: Performs software rendering. This device was introduced with DirectX 9.0. [141] Every device contains at least one swap chain. A swap chain is made up of one or more back buffer surfaces. Rendering occurs in the back buffer.
