NVIDIA had earlier described DLSS 5 in a way that suggested a deeper understanding of the scene. The follow-up answers paint a narrower picture. When asked whether the model reads PBR (Physically Based Rendering) properties from the engine, NVIDIA said: “DLSS 5 only takes the rendered frame and: “DLSS 5 only takes the rendered frame and motion vectors as inputs. Materials are inferred from the rendered frame.” In other words, the model is not reading metallic, roughness, normal maps, or other underlying material properties directly.
