Vulkan SDK 1.4.313.0 Release Notes
Version 1.4.313.0 for Windows
May 6, 2025
This SDK supports Vulkan API revision 1.4.313.
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
Visual Studio 2019 will be deprecated in the future and when this happens, SDKs will require the use of Visual Studio 2022.
Overview of new features in SDK 1.4.313.0
- 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_QCOM_tile_memory_heap
- VK_NV_external_compute_queue_vendor
- VK_QCOM_tile_shading
- VK_EXT_fragment_density_map_offset
- VK_KHR_shader_bfloat16
- Multiple enhancements to vkconfig3
- Support of dark mode
- Removal of vkVIA. All diagnostic information provided by vkVIA is now in the System Diagnostic tab of the Vulkan Configurator
- Creation of log files to be submitted with a Vulkan bug report.
- Multiple additional enhancements. See the vkconfig changelog
- Cross compiling enhancements:
- The Windows ARM libraries and DLLs are included in the Windows/X64 SDK to enable cross-compile. You can find the libraries in the Lib-ARM64 and Bin-ARM64 directories.
- The Windows/x64 libraries and DLLs are included in the Windows ARM SDK to enable cross-compile. You can find the libraries in the Lib-X64 and Bin-X64 directories
- No other tools are provided, SDK users are expected to configure their tools themselves to enable cross compiling, and the DLLs and LIBS are provided to make linking and packaging possible on both platforms..
- A new validation error was added that will likely catch many applications not using semaphores in swapchains correctly. For details on how to fix it in your application see the Vulkan Guide
- 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.
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

Specifies list of frames to output as screenshots. It is specified as a comma-separated list of frames or a range of frames with a start, count, and optional interval separated by a dash. Setting the variable to "all" will output every frame. Example: "5-8-2" will output frame 5, continue until frame 13, dumping every other frame. Example: "3,8-2" will output frames 3, 8, and 9. If it is not set or it set to an empty string, no screenshots are created.
