Description

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

Revision 2 adds entry points exposing the legacy NVIDIA Reflex implementation. These are only intended for use by compatibility layers, applications should not call these methods directly.

Note

There is currently no specification language written for this extension. The links to APIs defined by the extension are to stubs that only include generated content such as API declarations and implicit valid usage statements.

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.
