Microsoft has launched a public preview of DirectX Dump Files, designed to improve the debugging process for GPU crashes on Windows. The .dxdmp files are created when a hardware error is detected and contain hardware snapshots, driver data, Direct3D runtime context, and application user data. Developers need to meet specific requirements, including using Windows 24H2 or 25H2 with update KB5089573 or later, Windows 26H1 with update KB5089570 or later, Agility SDK Update Package 1.721.1-preview, and enabling developer mode. Additionally, AMD Software AgilitySDK Developer Preview Edition 26.10.07.02 is required for AMD graphics cards, along with compatible benchmark drivers from Intel, NVIDIA, and Qualcomm, and PIX version 2606.18-preview for analyzing dump files. The tool is currently focused on gathering developer feedback and is not intended for retail game integration. Developers can choose between three operational modes: NOOVERHEAD, MEDIUMOVERHEAD, and HIGH_OVERHEAD. The full launch is expected in fall 2026.
