I don’t know but when using Nanite and Lumen, more info here Nanite Virtualized Geometry in Unreal Engine | Unreal Engine 5.6 Documentation | Epic Developer Community ray-tracing is sort of needed.
What I did recently was to edit materials, removing the Roughness texture to stay within the default value.
As far as I can recall the Epic Games Citizen people pack uses an increased amount of SRVs, and which can be changed in a source build, when editing the default value via Visual Studio. There is a topic on this somewhere on the forums (also replied there around 2023/2024.
Bottom line increase can be mitigated by editing the material, recommended.
