Download DirectX 12

A game crashing with a missing DLL error, like d3dx9_43.dll or d3dcompiler_47.dll, is one of the most common reasons people download DirectX 12. Developed by Microsoft, DirectX is the set of APIs Windows relies on to talk to your graphics card, sound hardware, and input devices, and most modern PC games are built directly on top of it.

Even though Windows 10 and 11 ship with a version of DirectX built in, some older or specific games need extra runtime components that only the standalone redistributable installs. Running it once resolves the vast majority of these launch errors.

Key Features of DirectX 12

• Installs any missing legacy DirectX DLL files a game might need
• Improved multi-threading support for better use of multi-core CPUs
• Lower-level hardware access for more efficient rendering performance
• Explicit multi-adapter support for systems with multiple GPUs
• Ray tracing support (DirectX Raytracing) on compatible hardware
• Backward compatible with games built for earlier DirectX versions
