The shader, developed by Pascal Gilcher (known as Marty McFly ), represents a pivotal moment in post-processing technology, effectively "democratizing" ray tracing for thousands of legacy and modern games that lack native support. By injecting code that accesses a game’s depth buffer, this version of the Ray Traced Global Illumination (RTGI) shader simulates realistic light behavior—such as light bouncing and color bleeding—to transform flat, rasterized scenes into immersive, photorealistic environments. The Core Technology: Screen Space Ray Tracing

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 The Depth Pre-Pass & Normals Benefits of ReShade RTGI 0
