# vkAntiLagUpdateAMD(3) Manual Page

## Name

vkAntiLagUpdateAMD - Provide information to reduce latency

Loading… please wait.

## C Specification

To lower latency, call:

    // Provided by VK_AMD_anti_lag
    void vkAntiLagUpdateAMD(
        VkDevice                                    device,
        const VkAntiLagDataAMD*                     pData);

## Parameters

- `device` is the logical device

- `pData` is a pointer to a VkAntiLagDataAMD structure containing latency reduction parameters.

## Description

This command should be executed immediately before the application processes user input. If `pData` is not `NULL` and VkAntiLagDataAMD::`pPresentationInfo` is not `NULL`, this command should be executed again before vkQueuePresentKHR, with `pPresentationInfo` set to matching values.

Valid Usage

- VUID-vkAntiLagUpdateAMD-antiLag-10061
  The `antiLag` feature must be enabled

Valid Usage (Implicit)

- VUID-vkAntiLagUpdateAMD-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkAntiLagUpdateAMD-pData-parameter
  `pData` must be a valid pointer to a valid VkAntiLagDataAMD structure
