Introduction The DirectX Control Panel (DXCPL) is a Microsoft tool that provides runtime configuration options for Direct3D applications. Historically included in the DirectX SDK and the legacy DirectX SDK (June 2010), DXCPL exposes settings such as debug layers, debug output, and device selection that can be invaluable for developers diagnosing graphics issues, testing feature support, or forcing particular Direct3D behaviors. On contemporary 64‑bit Windows 10 systems, obtaining and running DXCPL requires attention to compatibility and source authenticity because Microsoft moved much of DirectX functionality into the Windows SDK and the DirectX End‑User Runtimes were reorganized.
