# VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV(3) Manual Page

## Name

VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV - Structure describing fragment shading rate limits that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV` structure is defined as:

    // Provided by VK_NV_fragment_shading_rate_enums
    typedef struct VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV {
        VkStructureType          sType;
        void*                    pNext;
        VkSampleCountFlagBits    maxFragmentShadingRateInvocationCount;
    } VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV;

## Members

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

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

- `maxFragmentShadingRateInvocationCount` is a VkSampleCountFlagBits value indicating the maximum number of fragment shader invocations per fragment supported in pipeline, primitive, and attachment fragment shading rates.

## Description

If the `VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These properties are related to fragment shading rates.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceFragmentShadingRateEnumsPropertiesNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FRAGMENT_SHADING_RATE_ENUMS_PROPERTIES_NV`
