Description

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

New Structures

• Extending SemaphoreCreateInfo:

  • QueryLowLatencySupportNV

New Enum Constants

• NV_LOW_LATENCY_EXTENSION_NAME

• NV_LOW_LATENCY_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_QUERY_LOW_LATENCY_SUPPORT_NV

Issues

1) Why does QueryLowLatencySupportNV 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.
