Although its best-known component is Direct3D for 3D graphics, it also includes specialized components such as Direct2D (2D vector graphics), DirectWrite (typography), XAudio2 (surround sound), and XInput (gamepad control). This ecosystem, which was created in the Windows 95 era to unify access to hardware on PCs, later became the cornerstone for Xbox game consoles. The golden age of "high-level" versions is symbolized by the legendary DirectX 9 (dominant on Windows XP), the groundbreaking DirectX 10 with the new WDDM driver model in Windows Vista, and DirectX 11, which became the de facto graphics standard for the entire past decade. The advent of "low-level" DirectX 12 put memory management, synchronization, and command queuing directly into the hands of developers, allowing them to scale better on multi-core processors and minimize driver overhead. The pinnacle of the current lineup is represented by the DirectX 12 Ultimate brand, which brings together the most advanced hardware features - Ray Tracing 1.1 for realistic lighting effects, Mesh Shaders for flexible geometry processing, Variable Rate Shading for smart performance savings, and Sampler Feedback for optimized texture streaming.
