Improved algorithms to reduce the "noise" often associated with ray tracing, leading to a cleaner image.

Adds realistic shadow casting and material interaction that adapts to the in-game environment.

The ReShade RTGI shader is a post-processing effect that simulates . Unlike traditional baked lighting, RTGI facilitates real-time interactive "bounce lighting," where light reflects off surfaces to illuminate areas not directly hit by a primary light source. Key benefits of the 0.33 version include:

Best used with the "Launchpad" pre-pass shader, which provides motion estimation using optical flow for more precise lighting updates.

Unlike native RTX implementations, RTGI operates solely on depth data, making it compatible with non-RTX video cards.

Accurate modeling of both diffuse and specular light, ensuring that shiny surfaces reflect the environment correctly. How to Install and Optimize RTGI 0.33
