How do DLSS and SER fit in with path tracing?

On your path-tracing developer page you list e.g. DLSS and SER as part of the “RTX Path Tracing core technologies”. How are they connected to path tracing?

Technically, they’re unrelated to path tracing. But they are both accelerating technologies that help to make real time path tracing possible. SER in particular is designed to accelerate GPU workloads that are divergent in nature. Path tracing is by its nature a very divergent workload, so SER happens to be particularly beneficial for path tracing.
