DirectX Runtimes and SDKs
| Component | Description | Link |
| DirectX 12 Agility SDK | SDKs with support for the latest DirectX 12 features that run on Windows 10 Version 1909 (Windows 10 November 2019 Update) and up | DirectX 12 Agility SDK Landing Page
Note that the DirectX team will keep on shipping DirectX 12 updates with Windows 10; the Agility SDK is intended for developers looking to bring our latest features to a large install base |
| D3D12on7 | Windows 7-compatible DirectX 12 runtime with support for the RS5 (Windows 10 October 2018 Update) feature set | Porting DirectX 12 Games to Windows 7 |
| DirectStorage | DirectStorage is a feature intended to allow games to make full use of high-speed storage (such as NVMe SSDs) that can can deliver multiple gigabytes a second of small (eg 64kb) data reads with minimal CPU overhead | DirectStorage API Downloads |
| Other DirectX NuGet Redistributable Packages | Microsoft.DXSDK.D3DX provides the legacy D3DX9, D3DX10, and D3DX11 utility libraries for maintaining older codebases and includes side-by-side redistributable binaries
Microsoft.XAudio2.Redist provides XAudio 2.9 for Windows 7 SP1 or later with side-by-side redistributable binaries |
Microsoft.DXSDK.D3DX NuGet |
| Legacy Runtimes | Developers maintaining older software can still find the legacy runtime installer and SDK | DirectX End-User Runtimes (June 2010)
Microsoft Desktop Bridge “DirectX Framework” Packages: x86 / x64 |
Tools
| Component | Description | Link |
| DirectX Shader Compiler aka DXC | Compiler and related tools used to compile High-Level Shader Language (HLSL) programs into DirectX Intermediate Language (DXIL) representation | DirectXShaderCompiler repo
Note that the Windows 10 SDK already comes with a version of the Shader Compiler. Downloading the latest Shader Compiler is recommended for developers looking for the newest HLSL features |
| PIX on Windows | Microsoft’s DirectX debugging and profiling tool, allowing devs to find issues and do performance tuning | PIX Download Page |
| WinPixEventRuntime | Runtime package letting developers instrument PIX Events in their titles to enhance PIX captures | WinPixEventRuntime |
| DirectX Capabilities Viewer | Developer tool for viewing Direct3D hardware feature levels and optional feature support for Direct3D devices | DxCapsViewer repo |
| DirectX Debugging Tools (D3DDred.js) | WinDbg JavaScript extension that makes it much easier to debug D3D12 DRED (Device Removed Extended Data) state after a device removed event | DirectX-Debugging-Tools repo |
Frameworks
| Component | Description | Link |
| DirectML | High-performance, hardware-accelerated DirectX 12 library for machine learning, providing GPU acceleration for common machine learning tasks across a broad range of supported hardware and drivers | DirectML repo |
| WinML | High-performance API for deploying hardware-accelerated machine learning inferences on Windows devices | Introduction to WinML |
| Win2D | Windows Runtime API for immediate mode 2D graphics rendering with GPU acceleration | Win2D repo |
| DWriteCore | Text layout and glyph rendering API, now supported in Project Reunion | DWriteCore overview |
Helpers
| Component | Description | Link |
| DirectX Headers | Repo hosting the official Direct3D 12 headers, available under MIT. Includes the latest version of the D3DX12.H helper library | DirectX-Headers repo |
| DirectX Tool Kit for DX12 aka DirectXTK12 | Collection of helper classes for writing DirectX 12 code in C++ | DirectXTK12 repo |
| D3D12 Residency Starter Library | Library intended as a steppingstone to heaps/committed resources in a D3D12 app | D3DX12Residency repo |
| D3D12 MultiGPU Starter Library aka Affinity Layer | Library to help apps kickstart their MultiGPU implementation. Called the affinity layer because execution and resources can be ‘affinitized’ to one or more GPUs in the system | D3DX12AffinityLayer repo |
| DirectXTex | Texture processing helpers including BC codecs, mipmap generation, normal map conversion, etc. | DirectXTex repo |
| DirectXMesh | Geometry processing helpers including normals/tangent generation, vertex cache optimization, and meshtlet generation | DirectXMesh repo |
| DirectXMath | All-inline SIMD C++ linear algebra library for use in games and graphics apps | DirectXMath repo |
