Change log for September 29, 2023 Vulkan 1.3.266 spec update:

Github Issues

  * Fix slink:VkGraphicsPipelineCreateInfo VU to say a valid pipeline layout
    is always needed without a graphics pipeline library (public issue
    2168).

    and pname:depthBoundsTestEnable (internal issue 3486)
  * Fix stride passed to flink:vkGetQueryPoolResults in example code in
    apiext:VK_KHR_performance_query appendix (internal MR 6148).

+
+=== Description
+
+This extension gives applications timing suggestions on when to start the
+recording of new frames to reduce the latency between input sampling and
+frame presentation.
+Applications can accomplish this through the extension by calling
+flink:vkSetLatencySleepModeNV to allow the driver to pace a given swapchain,
+then calling flink:vkLatencySleepNV before input sampling to delay the start
+of the CPU side work.
+Additional methods and structures are provided to give insight into the
+latency pipeline of an application through the latency markers.
+`apiext:VK_NV_low_latency` provides legacy support for applications that
+make use of the NVIDIA Reflex SDK whereas new implementations should use the
+`apiext:VK_NV_low_latency2` extension.
+
+=== Issues
+
+1) How does Low Latency 2 work with applications that utilize device groups?
+
+Low Latency 2 does not support device groups.
