Perform Synchronization Command包括set/wait events, pipeline barrier, render pass/subpass dependencies,其实也就是同步Command。在这里只有Aciton Command需要同步操作。 在Vulkan中的Operation代表了在CPU、GPU或外部实体(如演示引擎)上执行的任意数量的工作。而Action Command会包含多个Operation。 同步Command通过同步作用...

(introduced in VK_KHR_dynamic_rendering, promoted to Vulkan 1.3) instead of VkRenderPass objects. Another examples include use of dynamic state, VK_EXT_graphics_pipeline_library (or VK_EXT_shader_object), VK_KHR_synchronization2, timeline semaphores, descriptor buffers, descriptor indexing and ...
It's tough to interpret, but my overall impression is it's bottlenecked by some kind of synchronization stall between CPU/GPU. The trace suggests that vkCreateSwapchainKHR, vkDestroySwapchainKHR returns line up with the FlipWait interval and so perhaps these functions are stalled by vblank (...
What happened in my case, was that after swap chain recreation I lost synchronization between frame buffers and respective swap chain images. This resulted in using wrong frame buffers and thus rendering to different images than requested by the swap chain. ...
