Vulkan SDK 1.3.268.0 Release Notes

Version 1.3.268.0 for Windows
October 24, 2023

This SDK supports Vulkan API revision 1.3.268.

Overview of new features in SDK 1.3.268.0

Drivers: It is recommended you update Vulkan-capable hardware drivers to the latest recommended version from the hardware vendor. A list of Known Issues appears at the end of this document with more information.

Vulkan Loader: The Windows SDK does not update the Vulkan Loader on your system. Instead you should be getting the Vulkan Loader from your graphics hardware provider driver package. There is an optional Vulkan Runtime package available at vulkan.lunarg.com should you wish to force updating your system with a more recent Vulkan Loader.

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

New Layer Manifest File version: The new version of the Layer Manifest File may cause an older Vulkan Loader to generate a warning. This warning is safe to ignore. It appears like the following with a corresponding SDK path and layer name:

WARNING: [Loader Message] Code 0 : loaderAddLayerProperties: [path\to\sdk]VkLayer_[layer_name].json invalid layer manifest file version 1.2.0.  May cause errors.

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

Possible Conflict between Vulkan Profiles Layer and Vulkan Hardware Capability Viewer: If the the Vulkan Profiles layer is active (perhaps via the Vulkan Configurator) and the Vulkan Hardware Capability Viewer is started, you may get the message "Feature modifying tool detected, upload disabled". This can occur on installation of a new SDK if autolaunch of Vulkan Configurator and and the capabilities viewer is selected, when the last selected configuration includes the profile layer.
