LunarG releases GFXReconstruct, a new Vulkan Capture/Replay Tool, with SDK 1.2.141

LunarG has released new Windows, Linux, and macOS SDKs for Vulkan header The prior SDK supported Vulkan API revision 1.2.135. The DirectX Shader Compiler (DXC) executable and GFXReconstruct, a new Vulkan capture/replay tool, debut with this SDK. Read on for information about other new features in this SDK.

Overview of Vulkan SDK 1.2.141

The following new features are included:

    • GFXReconstruct, a new Capture/Replay tool. See the GFXReconstruct documentation for more details.
    • The DirectX Shader Compiler (DXC) executable (for Windows SDK only at this time). See the DXC documentation for more details.
    • Versions of the Vulkan Specification have been generated that result in VUIDs being visible within the specification text.
      • Errors from the Validation Layers included with this SDK will provide links to the appropriate VUID section within this VUID annotated specification.
      • This improves the usability of deciphering a validation error.
      • The specifications are included with the SDK documentation online at
    • Support for the following new extensions:
      • VK_EXT_private_data
      • VK_EXT_custom_border_color
      • VK_EXT_robustness2
      • VK_QCOM_render_pass_shader_resolve
      • VK_QCOM_render_pass_store_ops
    • Bug fixes and improved validation coverage
