Discover all the exciting new updates and improvements available to developers in the April 2025 GDK release.
The April 2025 Microsoft Game Development Kit (GDK) update has landed with a targeted set of improvements. Whether you’re smoothing out certification, grabbing HDR screenshots, or stepping through optimized code, these focused tweaks remove friction and keep your workflow moving. Here are the key highlights.
Submission Validator Enhancements for Smoother Certification
Submission Validator has received important upgrades to make your submission process more straightforward and compliant. It now strictly enforces the use of approved GDK versions for PC submissions, safeguarding your projects against potential compatibility issues. Additionally, new file size checks have been implemented: warnings are issued at package sizes of 450GB, with errors flagged at 500GB, helping you avoid certification delays and streamline compliance processes. Detailed guidance is available at aka.ms/EmbeddedGDKVersion.
Introducing WdCapture CLI for Quick and Effective Screenshot Management
A brand-new command-line interface (CLI) tool, WdCapture, is now available for capturing screenshots effortlessly on PC. Supporting both Standard Dynamic Range (SDR) and High Dynamic Range (HDR) formats, WdCapture lets developers save screenshots as PNG or JXR files. This flexible tool allows you to set custom file paths and select specific displays, simplifying screenshot management during development.
Powerful Debugging with Visual Studio 2022 C++ Dynamic Debugging
The April 2025 release introduces significant advancements in debugging with Visual Studio 2022's new C++ Dynamic Debugging feature. Developers can now debug optimized C++ code dynamically without impacting performance. Set breakpoints and step into functions with ease thanks to on-demand function deoptimization. This powerful tool requires Visual Studio 2022 version 17.14 Preview 2 or newer. More information can be found at aka.ms/dynamicdebugging.
PIX Enhancements for Improved CPU Timeline Visualization
The PIX tool receives valuable updates to Direct3D context event handling. Developers can now initiate and conclude PIX events involving Direct3D contexts across different CPU threads, significantly enhancing flexibility. CPU work timelines are displayed more clearly, with start and end times now marked distinctly per CPU thread, making it easier to visualize and optimize performance.
