Description

Processing multiple draw commands in sequence incurs measurable overhead within drivers due to repeated state checks and updates during dispatch. This extension enables passing the entire sequence of draws directly to the driver in order to avoid any such overhead, using an array of MultiDrawInfoEXT or MultiDrawIndexedInfoEXT structs with cmdDrawMultiEXT or cmdDrawMultiIndexedEXT, respectively. These functions could be used any time multiple draw commands are being recorded without any state changes between them in order to maximize performance.

data PhysicalDeviceMultiDrawFeaturesEXT

VkPhysicalDeviceMultiDrawFeaturesEXT - Structure describing whether the implementation supports multi draw functionality

Members

This structure describes the following features:

Description

If the PhysicalDeviceMultiDrawFeaturesEXT 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. PhysicalDeviceMultiDrawFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
