Description
It'd be super nice to have a sample demonstrating DXGI 1.3's frame latency waitable objects for doing low latency rendering with D3D12. Currently the Hello Frame Buffering has a latency of ~70ms, but getting to ~30ms isn't out of the question with some relatively minor changes.
It'd also be useful to have an app that can test a system's speed-of-light lowest latency present path, since this has been an issue that cropped up more than once in general and especially on MsHybrid systems.
FWIW, I'm using PresentMon to measure the above latencies.

Research direction
Start by reviewing the existing Hello Frame Buffering sample and the issue's PresentMon latency measurements. The work is done when a D3D12 sample demonstrates DXGI 1.3 frame latency waitable objects and evaluates the lowest-latency present path, including the MsHybrid scenario described here.
