Simulates how light from a primary source (like the sun or a lamp) bounces off surfaces to illuminate nearby objects, creating a more natural and cohesive look.
To give you a clearer idea of how different hardware handles RTGI, here is a compilation of user-reported performance from various community sources.
ReShade RTGI 0.36.1 remains a milestone in custom graphics technology. By bringing true path-traced global illumination to games that never supported it, it provides a dramatic, modern visual upgrade. Whether you are revisiting classics like Skyrim or updating modern masterpieces, this shader offers an unparalleled, photorealistic lighting experience. reshade rtgi 0361
Because the shader doesn't know what is happening off-screen, turning your camera away from a bright light source will cause its reflected light to vanish from the edges of your screen.
Later experimental versions of the RTGI shader sometimes pushed the boundaries of temporal accumulation, leading to "ghosting" (trails behind moving objects) or flickering in high-contrast scenes. Version 0361 struck a masterful balance. It offers robust ray tracing calculation without the heavy temporal artifacts that plague "bleeding edge" releases. It is stable enough for fast-paced action games while retaining the visual fidelity needed for slow-paced RPGs. Simulates how light from a primary source (like
This is why games often feel "gamey" or artificial. They lack the cohesion of light traveling through an environment.

At its core, RTGI 0361 uses Monte Carlo integration to sample light paths. Each "ray" thrown into the scene is a stochastic sample, and more rays result in lower noise and higher quality, at the cost of performance. This version struck a particular balance between visual fidelity and computational efficiency, making it a popular choice for tinkerers.
