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.
1) How does Low Latency 2 work with applications that utilize device groups?
Low Latency 2 does not support device groups.
