Version 0.17.0.2 introduced several critical refinements that improved both visual fidelity and performance:
A critical stepping stone in real-time graphics modding, but effectively obsolete for daily driver usage due to performance inefficiencies and superior alternatives now available.
Unlike hardware-native ray tracing built into modern game engines (such as Unreal Engine or Unity), RTGI functions as a .
Unlike native hardware-accelerated ray tracing (such as Nvidia RTX or AMD DXR), which requires dedicated RT cores and direct engine code integration, . The Core Capabilities of the 0.17.0.2 Architecture: rtgi 0.17.0.2
This version relies on a voxel-based approach for indirect lighting calculations, distinct from earlier pure screen-space methods.

Architectural and algorithmic notes
is a landmark legacy version of the Ray Traced Global Illumination shader, developed by Pascal Gilcher (also known as Marty McFly) for the universal post-processing injector ReShade. Released via Pascal Gilcher’s Patreon , version 0.17.0.2 became a highly sought-after, foundational build for PC modders looking to inject screen-space software ray tracing into classic, pre-RTX era video games. What is RTGI 0.17.0.2?
Adds depth to indoor scenes and realistic sunlight bounce that the original engine misses.
