Setting up the shader requires a few precise steps to ensure ReShade can properly access your game's data.
rtgi (real-time global illumination) is an open-source project that implements dynamic global illumination techniques for real-time rendering. Version 0.17.0.2 continues the project’s steady evolution: it tightens performance, expands platform compatibility, and refines quality-vs-cost trade-offs. This column examines what’s new, how the internals behave, practical integration concerns, and when you should — or shouldn’t — adopt this release.
Marty McFly’s RTGI is a premium shader available through his Patreon page. Once acquired, copy the qquint_rtgi.fx file into your game's reshade-shaders/Shaders folder, and the corresponding textures into the reshade-shaders/Textures folder. rtgi 0.17.0.2
Because RTGI 0.17.0.2 relies on spatial geometry data, a broken depth buffer results in completely flat lighting or an entirely black screen.
Why: This dictates how far a light ray travels before stopping. Too high, and light will leak through walls; too low, and you won't see global illumination in large rooms. Z-Thickness 0.05 to 0.15 Setting up the shader requires a few precise
Determines how far light rays travel. Longer rays increase quality but hurt performance.

Among the many release milestones in RTGI's development history, version stands out as a major leap forward in performance and optimization—and it continues to be referenced by modders and preset creators today. This article explores everything you need to know about RTGI 0.17.0.2, how it works, how to install and configure it, where the technology stands now, and why this release remains a landmark moment in real-time graphics modding.
In traditional game rendering (rasterization), light typically travels in a straight line from the source to the object. If a red carpet is hit by sunlight, the nearby white wall stays white. In the real world, however, light bounces. That red carpet would reflect a subtle red glow onto the white wall—a phenomenon known as "color bleeding" or global illumination.

The RTGI 0.17.0.2 release helped solidify screen-space ray tracing as a viable middle-ground between no ray tracing and hardware-heavy native ray tracing. It allowed users to breathe new life into older classics like The Witcher 3 , Grand Theft Auto V , or The Elder Scrolls V: Skyrim .
