Vulkan SDK 1.4.328.1 Release Notes
October 8, 2025
Overview of new features in SDK 1.4.328.1
Version 1.4.328.1 addresses a potential crashing bug in the Vulkan Validation Layer and restores vulkan.cppm and vulkan_video.cppm to the distribution.
Version 1.4.328.0 for Windows
October 7, 2025
Overview of new features in SDK 1.4.328.0
This SDK supports Vulkan API revision 1.4.328.
SDK Version Lifetime Vulkan SDK's older than 2 years are removed from the Vulkan SDK download site and won't be available once removed. All SDK's are backwards compatible and using the latest or newer SDK is recommended due to ongoing bug fixes and enhancements in the SDK content.
Deprecation Notice
This is the LAST SDK release that will support VS2019. Beginning with the next SDK (December timeframe), only VS2022 will be supported.
Overview of new features in SDK 1.4.328.0
The Vulkan headers now include the following new extensions. Note that extensions are optional and may not be implemented by the underlying driver/ICD. Applications can now query for the presence of these new features.
- VK_KHR_copy_memory_indirect
- VK_VALVE_video_encode_rgb_conversion
- VK_KHR_shader_untyped_pointers
- VK_AMDX_dense_geometry_format
Vulkan Configurator new has a “Vulkan drivers tab” that allows Vulkan developers to :
- Add additional Vulkan drivers (for example Lavapipe on Windows)
- Force the Vulkan physical device used by Vulkan applications
- Order the list of Vulkan physical devices
The spirv-remap utility from glslang has been ported to the SPIRV-Tools repository in the form of an optimization pass called canonicalize-ids. See the usage (spirv-opt --help) for more details. The spirv-remap utility in glslang has been removed in favor of the canonicalize-ids pass in spirv-opt and should be functionally equivalent.
Improved validation coverage. VUID validation coverage documentation (validation_error_database.csv and validation_error_database.html) has been updated to represent the validation layer VUID coverage status.
SDL3 is now distributed as part of the SDL optional package.
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.

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 installatiion, 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
