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
VkMultiDrawInfoEXT or VkMultiDrawIndexedInfoEXT structs with
vkCmdDrawMultiEXT
or vkCmdDrawMultiIndexedEXT
, 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.
