| === 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 |
| slink:VkMultiDrawInfoEXT or slink:VkMultiDrawIndexedInfoEXT structs with |
| fname:vkCmdDrawMultiEXT or fname: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. |
