Yes and no. They are very similar approaches executed slightly differently. They both handle direct lighting and shadows in essentially the same way. Nvidia’s path tracing also handles most GI (but not yet from the skylight so it looks kinda terrible outdoors) and some rough reflections, which megalights is falling back onto lumen for.
I bet the difference is mostly due to Nvidia using ray reconstruction for that demo and if that was off they’d behave very similarly with moving lights
