RTGI 0.33 works by analyzing a single frame of a game (the depth buffer and color buffer ) and tracing rays in screen-space. It asks: "Where is light bouncing from the pixels I can see?" : Unlike native NVIDIA RTX or AMD Ray
While the RTGI 0.3.3 shader offers impressive lighting capabilities, users should be aware of potential performance impacts. Ray tracing and global illumination calculations can be computationally intensive, potentially affecting frame rates, especially in more complex scenes.
Released during the 2021–2022 period as a significant update, version 0.33 introduced technical improvements to enhance both visual quality and performance: Motion Vector Support
