is a revolutionary post-processing shader developed by Pascal Gilcher (Marty McFly) that brings advanced lighting effects to games that don't natively support them. Version 0.36.1 represents a stable, highly popular iteration of this tech, often favored for its balance of visual fidelity and performance on non-RTX hardware. What is RTGI 0.36.1? Unlike native hardware ray tracing (like in Metro Exodus ), RTGI uses screen-space path tracing

It provides highly accurate contact shadows in corners and crevices, adding depth and "weight" to 3D objects.
