rtgi v ray traced reflections: The Brutal Honest Review
RTGI and ray traced reflections are both techniques for rendering realistic reflections in 3D graphics. RTGI is a rasterization-based technique that uses a hierarchical approach to approximate ray tracing, while ray tracing is a brute-force technique that traces rays from the camera through the scene to compute the color of each pixel. RTGI is generally faster than ray tracing, but it can produce less accurate results, especially for complex scenes with many reflective surfaces. Ray tracing, on the other hand, is slower but can produce more accurate results, even for complex scenes.
