RTGI (Ray Traced Global Illumination) 0.17.0.2 was a pivotal beta release of the screen-space ray tracing shader developed by (also known as Marty McFly) . The "Story" of this Version
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.
RTGI stands for . It is a post-processing shader injected into games via the ReShade framework.
In standard rasterized games (e.g., Skyrim, GTA V, Fallout 4, or even Elden Ring), shadows are often "hard" and ambient light is faked using ambient occlusion (AO) and pre-baked light maps. RTGI scans the depth buffer and color buffer in real-time, traces rays from the camera’s perspective, and intelligently bounces light off surfaces. The result? Diffuse illumination, color bleeding, and realistic soft shadows that adapt as the camera moves. rtgi 0.17.0.2
More samples create less noisy shadows but require more GPU power. Depth Cutoff:
Traditional video game lighting often relies on "ambient light," which uniformly brightens a room regardless of its geometry. RTGI completely replaces this lazy approach with physical calculations:
In this article, we will dissect RTGI 0.17.0.2, exploring what it is, its new features, performance metrics, installation methodology, and how it compares to its predecessors. RTGI (Ray Traced Global Illumination) 0
That clock had never received light before. Not in any version.
The screen flickered, and the hallway changed.
In essence, RTGI adds:
Earlier builds suffered heavily from "noise" or graininess due to sparse ray counts. Build 0.17.0.2 drastically improved spatial filtering, which merges pixels intelligently to smooth out grainy artifacts without blurring finer geometry details. 2. Enhanced Temporal Stability
RTGI 0.17.0.2 is – expect 20–40% FPS drop at 1080p with bounce count=2.
– Copy any .ini configuration file (the preset) provided by the mod author into your game's root folder or the reshade-shaders\Presets directory. It is a post-processing shader injected into games
For several years, the state of the art in real‑time global illumination has been , a sampling technique first published by NVIDIA researchers and later integrated into games like Cyberpunk 2077 (Update 2.1) and various Unreal Engine 5 branches.
