: Perhaps the most famous post-processing shader, RTGI (often called "the ray tracing ReShade") works on nearly any game by utilizing the depth buffer. It is available through Marty's Mods and usually requires a Patreon subscription for the latest builds.
Screen-Space Ray Traced Global Illumination (SSRTGI) shaders have become a transformative tool for gamers and developers, offering a way to add realistic, dynamic lighting to almost any game without needing a high-end RTX graphics card. Unlike traditional lighting that only accounts for direct rays, SSRTGI simulates how light bounces off surfaces, filling in shadows and adding subtle color bleeding that mimics real-world physics.
