VkPhysicalDeviceAntiLagFeaturesAMD(3)

# VkPhysicalDeviceAntiLagFeaturesAMD(3) Manual Page

## Name

VkPhysicalDeviceAntiLagFeaturesAMD - Structure describing whether VK_AMD_anti_lag can be supported by an implementation.

## C Specification

The `VkPhysicalDeviceAntiLagFeaturesAMD` structure is defined as:

    // Provided by VK_AMD_anti_lag
    typedef struct VkPhysicalDeviceAntiLagFeaturesAMD {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           antiLag;
    } VkPhysicalDeviceAntiLagFeaturesAMD;

## Members

This structure describes the following feature:

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

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

- `antiLag` indicates whether the implementation supports AMD Radeon™ Anti-Lag functionality. The `antiLag` feature only supports a single GPU and must not be enabled if VkDeviceGroupDeviceCreateInfo::`physicalDeviceCount` is greater than 1.

## Description

If the `VkPhysicalDeviceAntiLagFeaturesAMD` 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. If the application wishes to use a VkDevice with any features described by `VkPhysicalDeviceAntiLagFeaturesAMD`, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the `pNext` chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceAntiLagFeaturesAMD-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ANTI_LAG_FEATURES_AMD

Structure Chaining
