A look at the tech demo 'Zorah' from NVIDIA. This was run in the stock UE5 editor, so it doesn't use Mega Geometry or RTXDI.

For a comparison between stock UE5 and the NvRTX version with additional features, see this video: youtube.com/watch?v=zdbjsO8k8mM

Note that GPU temperature monitoring doesn't appear to be working in the Unreal Engine editor. Actual was between 50-60 degrees.
