data SetPresentConfigNV Source #

VkSetPresentConfigNV - Structure specifying present metering configuration

Description

The metering configuration applies to all swapchains in the array in PresentInfoKHR. The configuration specified by SetPresentConfigNV applies to the next numFramesPerBatch calls to queuePresentKHR and needs to be updated every numFramesPerBatch presents.

VkPhysicalDevicePresentMeteringFeaturesNV - Structure describing whether the present metering features can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDevicePresentMeteringFeaturesNV 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. If the application wishes to use a Device with any features described by PhysicalDevicePresentMeteringFeaturesNV, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
