April 2025 GDK Update

✨Features

  • Developer Tools:
    • Submission Validator
      • Submission Validator now enforces approved GDK versions for PC titles. For more information go to https://aka.ms/EmbeddedGDKVersion.
      • Submission Validator now checks your package size. We will issue a WARNING at 450GB and an ERROR at 500GB.
    • WdCapture (Screenshot) command line interface (CLI) support
      • This feature is a PC command line interface (CLI) tool designed to capture screenshots on PC using windows graphics APIs.
      • It supports both SDR AND HDR format and saves file captures in PNG or JXR format.
      • Users can specify file paths to save screenshots and specify the display for capture.
    • Visual Studio 2022 C++ Dynamic Debugging Support
      • C++ Dynamic Debugging offers a full debugging experience for optimized code without compromising performance. Place deoptimized breakpoints and step in anywhere with on-demand function deoptimization. To activate C++ Dynamic Debugging: Right-click on your project, Properties > Configuration Properties > Advanced > Advanced Properties > Use C++ Dynamic Debugging (preview).
      • Version 17.14 Preview 2 or newer of Visual Studio 2022 is required to use the dynamic debugging feature.
      • Go to https://aka.ms/dynamicdebugging to learn more.

October 2024 GDK Update

✨Features

  • Graphics: Auto-Vectorizer for 16-bit workloads: Optimization technique for Xbox 16-bit workloads, leveraging Xbox hardware instructions to improve runtime performance automatically. The feature is enabled by default for 16-bit workloads and can be turned off using __XBOX_ENABLE_AUTOVEC=0.
  • System: Console Developer Home Update: The streaming tab has removed the dropdown box to select the streaming protocol, simplifying the UX. The protocol is now automatically configured by client applications, and it is now possible to simultaneously listen for remote connect and direct connect requests. Active streams are disconnected when a new client connects.
  • Developer Tools: GDK Installer Updates: The installer now includes new links for additional tools upon installation. These tools are web-based or obtained via other channels and support various game creator tasks.
  • Developer Tools: Touch Adaptation Kit Command Line Tool (tak.exe): The TAK tool now listens for changes to the takxconfig.json file when using the serve command, allowing creators to swap out different asset directories, change configured languages, and see live updates to their bundle.
  • Developer Tools: TAK Feedback Improvements: The TAK tool now includes telemetry to help Microsoft improve the product. Use the tak.exe --help command to learn more.

🛠️Bug Fixes

  • Graphics: Fixed an issue where a rare assertion failure in XDXROfflineBVH.dll would occur when building an offline bottom-level acceleration structure (BLAS).
  • Game Chat 2: Fixed an issue that caused a crash in Game Chat 2 after the user changed their console language setting.
  • Shader Compiler: Fixed an issue where NGG_VS (compiler-based culling enablement) had a potential hardware hang with lots of fully culled groups.
  • Media: Fixed an issue that caused the title to stop responding upon source reader termination.
  • PIX: Fixed multiple issues in PIX, including crashes and errors related to GPU timings and corrupted ExecuteIndirect packets.
