You don't need a high-end GPU (ironically), but you need massive RAM (64GB+). Reflect4 relies on CPU-based spectral preprocessing for static geometry.

Unlike traditional engines (like Unreal Engine 5 or Unity’s HDRP), Reflect4 prioritizes spectral rendering over RGB rendering. While most software simulates red, green, and blue light, Reflect4 simulates light as a full spectrum (wavelengths from 380nm to 780nm). This results in "impossible realism"—images that look more like physical photographs than 3D renders. madewithreflect4

Traditional PBR (Metallic/Roughness) workflows do not work. Instead, you define materials using complex indices of refraction (IOR) per wavelength. A simple gold material might look like this in the Reflect4 shader language: You don't need a high-end GPU (ironically), but
