Description

This extension adds the VkQueryLowLatencySupportNV structure, a structure used to query support for NVIDIA Reflex.

New Structures

• Extending VkSemaphoreCreateInfo:
  • VkQueryLowLatencySupportNV

New Enum Constants

• VK_NV_LOW_LATENCY_EXTENSION_NAME
• VK_NV_LOW_LATENCY_SPEC_VERSION
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_QUERY_LOW_LATENCY_SUPPORT_NV

Issues

1) Why does VkQueryLowLatencySupportNV have output parameters in an input chain?

RESOLVED: We are stuck with this for legacy reasons - we are aware this is bad behavior and this should not be used as a precedent for future extensions.
