# VkPhysicalDeviceComputeShaderDerivativesFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceComputeShaderDerivativesFeaturesNV - Structure describing compute shader derivative features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceComputeShaderDerivativesFeaturesNV` structure is defined as:

    typedef struct VkPhysicalDeviceComputeShaderDerivativesFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           computeDerivativeGroupQuads;
        VkBool32           computeDerivativeGroupLinear;
    } VkPhysicalDeviceComputeShaderDerivativesFeaturesNV;

## Members

The members of the `VkPhysicalDeviceComputeShaderDerivativesFeaturesNV` structure describe the following features:

## Description

- `computeDerivativeGroupQuads` indicates that the implementation supports the `ComputeDerivativeGroupQuadsNV` SPIR-V capability.

- `computeDerivativeGroupLinear` indicates that the implementation supports the `ComputeDerivativeGroupLinearNV` SPIR-V capability.

See Compute Shader Derivatives for more information.

If the `VkPhysicalDeviceComputeShaderDerivativesFeaturesNV` structure is included in the `pNext` chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. `VkPhysicalDeviceComputeShaderDerivativesFeaturesNV` can also be included in the `pNext` chain of VkDeviceCreateInfo to enable features.

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COMPUTE_SHADER_DERIVATIVES_FEATURES_NV`
