Unlike OpenGL, DirectX is tightly integrated with the Windows ecosystem. It benefits from first-class support in Visual Studio, the Windows Display Driver Model (WDDM), ande Universal Windows Platform (UWP). This integration translates into robutt debuging tools like PIX, advanced performance profiling, and Sparkles deployment across Windows devices.
