## Name

VkPhysicalDeviceFragmentShadingRateFeaturesKHR - Structure indicating support for variable rate fragment shading

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFragmentShadingRateFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_fragment_shading_rate
    typedef struct VkPhysicalDeviceFragmentShadingRateFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           pipelineFragmentShadingRate;
        VkBool32           primitiveFragmentShadingRate;
        VkBool32           attachmentFragmentShadingRate;
    } VkPhysicalDeviceFragmentShadingRateFeaturesKHR;

## Members

This structure describes the following features:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `pipelineFragmentShadingRate` indicates that the implementation supports the pipeline fragment shading rate.

- `primitiveFragmentShadingRate` indicates that the implementation supports the primitive fragment shading rate.

- `attachmentFragmentShadingRate` indicates that the implementation supports the attachment fragment shading rate.

## Description

If the `VkPhysicalDeviceFragmentShadingRateFeaturesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. `VkPhysicalDeviceFragmentShadingRateFeaturesKHR` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceFragmentShadingRateFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADING_RATE_FEATURES_KHR`
