It bridges the gap between static, last-generation lighting and modern dynamic ray tracing. When configured correctly with the proper dependency files (Quint/FXShaders) and a resolution multiplier appropriate for the user's GPU, it provides an immersive visual overhaul that fundamentally changes the atmosphere of the rendered scene.

Performance tips:

RTGI is inherently noisy because it cannot cast infinite rays per frame. It uses temporal data to clean the image.
