public class VkSubpassResolvePerformanceQueryEXT
extends org.lwjgl.system.Struct<VkSubpassResolvePerformanceQueryEXT>
implements org.lwjgl.system.NativeResource

Structure specifying the efficiency of subpass resolve for an attachment with a format.

Description

If optimal is FALSE for a VkFormat, using a subpass resolve operation on a multisampled attachment with this format can incur additional costs, including additional memory bandwidth usage and a higher memory footprint. If an attachment with such a format is used in a multisampled-render-to-single-sampled subpass, the additional memory and memory bandwidth usage can nullify the benefits of using the VK_EXT_multisampled_render_to_single_sampled extension.

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_SUBPASS_RESOLVE_PERFORMANCE_QUERY_EXT

Layout

 struct VkSubpassResolvePerformanceQueryEXT {
     VkStructureType sType();
     void * pNext();
     VkBool32 optimal();
 }
