Vulkan SDK 1.3.280.0 Release Notes
Version 1.3.280.0 for Windows
March 19, 2024
This SDK supports Vulkan API revision 1.3.280.
Overview of new features in SDK 1.3.280.0
- VP_KHR_roadmap_2024 is now included in VP_KHR_roadmap.json that stores the Khronos roadmap profiles
- The Vulkan Profiles API library introduces a new BETA API, protected by the VP_USE_OBJECT define to enable using Vulkan functions loaded externally. Please, refer to the Vulkan Profiles API library documentation (https://vulkan.lunarg.com/doc/sdk/1.3.280.0/windows/profiles_api_library.html) for more information.
- The Vulkan Configurator (vkconfig) has been updated to improve quality and stability. See the fixes included in this SDK here. See the Vulkan Configurator documentation for more information.
- 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_NV_ray_tracing_validation
- VK_NV_raw_access_chains
- VK_EXT_map_memory_placed
- VK_NV_shader_atomic_float16_vector
- VK_KHR_video_decode_av1
- VK_KHR_dynamic_rendering_local_read
- VK_KHR_index_type_uint8 (promoted from EXT)
- VK_KHR_line_rasterization (promoted from EXT)
- VK_KHR_load_store_op_none (promoted from EXT)
- VK_KHR_shader_expect_assume
- VK_KHR_shader_float_controls2
- VK_KHR_shader_maximal_reconvergence
- VK_KHR_shader_quad_control
- VK_KHR_shader_subgroup_rotate
- 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.
- The Vulkan Capabilities viewer is now available on the Windows start menu
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.

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.
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.
