## Name

VkAntiLagDataAMD - Structure specifying the parameters for vkAntiLagUpdateAMD

Loading… please wait.

## C Specification

The `VkAntiLagDataAMD` structure is defined as:

    // Provided by VK_AMD_anti_lag
    typedef struct VkAntiLagDataAMD {
        VkStructureType                        sType;
        const void*                            pNext;
        VkAntiLagModeAMD                       mode;
        uint32_t                               maxFPS;
        const VkAntiLagPresentationInfoAMD*    pPresentationInfo;
    } VkAntiLagDataAMD;

## Members

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

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

- `mode` is a VkAntiLagModeAMD value specifying the anti-lag status.

- `maxFPS` is the framerate limit, in frames per second, used by the application. This limit will be imposed if anti-lag is enabled. If the application tries to render faster, the framerate will be reduced to match this limit. A value of 0 will disable the limit.

- `pPresentationInfo` is a pointer to a VkAntiLagPresentationInfoAMD structure containing information about the application stage.

## Description

This structure specifies anti-lag parameters.

Valid Usage (Implicit)

- VUID-VkAntiLagDataAMD-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_ANTI_LAG_DATA_AMD`

- VUID-VkAntiLagDataAMD-mode-parameter
  `mode` must be a valid VkAntiLagModeAMD value

- VUID-VkAntiLagDataAMD-pPresentationInfo-parameter
  If `pPresentationInfo` is not `NULL`, `pPresentationInfo` must be a valid pointer to a valid VkAntiLagPresentationInfoAMD structure
