Description

This extension automatically paces the CPU to make sure it does not get too far ahead of the GPU, reducing the latency between inputs received and updates on the screen. Additionally, Anti-Lag+ offers applications the ability to inform the driver when input processing begins, in order to align the timing of display updates, enabling even lower latency between receiving input and displaying on the screen.

Synopsis

Documentation

antiLagUpdateAMD Source #

Arguments

:: forall io. MonadIO io 
=> Device

device is the logical device

-> AntiLagDataAMD

pData is a pointer to a AntiLagDataAMD structure containing latency reduction parameters.

-> io () 

vkAntiLagUpdateAMD - Provide information to reduce latency

Description

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

Valid Usage

  • The antiLag feature must be enabled

Valid Usage (Implicit)

  • device must be a valid Device handle

data PhysicalDeviceAntiLagFeaturesAMD Source #

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

Members

This structure describes the following feature:

Description

If the PhysicalDeviceAntiLagFeaturesAMD structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceAntiLagFeaturesAMD can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

See Also

VK_AMD_anti_lag, Bool32, StructureType

Constructors

PhysicalDeviceAntiLagFeaturesAMD 

Fields

  • antiLag :: Bool

    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 DeviceGroupDeviceCreateInfo::physicalDeviceCount is greater than 1.
