Rtgi 0.17.0.2 Release _best_ Jun 2026

The algorithm for calculating how colored light reflects onto surrounding surfaces (e.g., a red wall casting a faint red tint onto a white floor) was refined for a more natural, subtle look.

The first major enhancement involved how the shader captured tiny geometric features. As shown in initial comparisons, small surface details—such as the step of a pillar—would often fail to cast sufficient bounce light onto adjacent walls. The new ray intersector in RTGI 0.17.0.2 was meticulously reworked to catch these small details effortlessly, resulting in significantly more accurate and "solid" lighting for fine surface geometry. rtgi 0.17.0.2 release

The release of RTGI 0.17.0.2 marks a major milestone for real-time ray-traced global illumination in modern PC gaming. Developed by Pascal Gilcher (McFlyPG), this Screen Space Ray Traced Global illumination (SSRTGI) shader for ReShade completely changes how legacy and modern titles handle lighting. By injecting path-traced lighting into games without native ray tracing support, this update provides enthusiasts with unprecedented visual fidelity.

It was widely tested and used in popular titles like GTA V , Skyrim SE , and Minecraft Java Edition to provide a "next-gen" visual look before official ray tracing updates were common. The new ray intersector in RTGI 0

With the release of , Pascal (often known as Marty McFly in the modding community) has pushed the shader even further. This isn't just a simple bug fix; it's a refinement of how the shader handles complex lighting scenarios.
