SDK Components

This version of the SDK is based on the following specifications, source code repositories, and commits:

LunarG would like to thank all of the many contributors to all of the above repositories and the contributions they are making to the Vulkan Ecosystem.

Submitting Issues

If while using the tools and layers included in the SDK you find a defect in that tool or layer, the most expedient way to get a resolution is to submit to its corresponding repository. For example, if you believe you have found a defect in the Validation Layers, submit an issue at the repository for Validation Layers. The only exception to this is for the shader tool chain (glslang, SPIRV-Cross, SPIRV-Tools, shaderc). For these repositories you can submit issues against the SDK at vulkan.lunarg.com.

Known Issues

No Warning with Profiles Use: When using Vulkan Profiles requiring Profiles with the Vulkan Profiles layer, no warning is emitted when trying to override a device capability to a value that is not supported by the device.

The Vulkan Runtime is now installed with the SDK. If the the loader (vulkan-1.dll) is in use during installation, the installation will fail and you will see an error message. You can update the runtime manually at any time by running VulkanRT.exe in the /Helpers folder in the SDK installation directory.

Vulkan Configurator known issues are documented in the Vulkan Configurator Change Log
