A public preview of Microsoft’s DirectX Dump Files provides developers with new tools to diagnose GPU crashes on Windows. The DirectX 12 feature generates a `.dxdmp` file whenever a graphics card stops responding or encounters a crash condition. This file captures the GPU execution state, driver details, and Direct3D runtime context at the moment of failure.
Developers can load the `.dxdmp` file into Microsoft’s PIX tool to inspect the failure without needing to recreate the crash on their local hardware. This feature serves game developers, engine teams, and QA studios rather than standard players.

AMD currently supports the feature in preview drivers for Radeon RX 7000 and Radeon RX 9000 series cards. Intel, NVIDIA, and Qualcomm support is currently limited to private developer channels.
Using the Agility SDK to test these dump files currently requires enabling Developer Mode on Windows. The update highlights Microsoft’s continuous push to improve developer profiling, following debugging enhancements introduced in the Windows 11 24H2 update. Microsoft expects to roll out broad hardware and retail game support in the fall of 2026.
