Rtgi 0.17.0.2
Version 0.17.0.2 acts as a highly refined polish on an already revolutionary tool, focusing heavily on reducing the "noise" and performance overhead traditionally associated with ray tracing. Key Features and Improvements in 0.17.0.2
Press the Home key to open ReShade, search for "RTG" or "McFly", and activate the shader. Limitations
While RTGI 0.17.0.2 is incredibly impressive, it is demanding. It is not designed to run on low-end systems without performance consequences.
), RTGI 0.17.0.2 traces rays against the screen and the depth buffer to generate diffuse global illumination and ambient occlusion.
She turned the avatar toward the fireplace. In reality, the fire had been the death of the house. In the simulation, she had never dared to turn it on. The emissive source—the flames—would always crash the shader. The logs would read: Unstable radiance cache . But version 0.17.0.2 had a new line: Improved stability near emissive sources. rtgi 0.17.0.2
Finally, v0.17.0.2 incorporated a that retained small details much better than previous versions. This refinement helped reduce the grainy or noisy appearance that can plague global illumination effects, especially in shadowed regions or complex scenes.
RTGI 0.17.0.2 is a version of the that enables screen-space ray tracing for global illumination. It works by analyzing the depth data of a game scene to trace rays and simulate how light interacts with surfaces, creating realistic, dynamic indirect lighting, color bleeding, and soft shadows. Key aspects of this specific 0.17.x era include:
In the rapidly evolving world of PC gaming graphics, few community-driven tools have made as significant an impact as . Specifically, the RTGI 0.17.0.2 beta release, released in late 2020 by developer Pascal Gilcher (Marty McFly), was a landmark version that significantly enhanced visual fidelity and temporal stability in thousands of titles.

Used in "UHG Reshade" presets to modernize the game's lighting.
RTGI 0.17.0.2 is – expect 20–40% FPS drop at 1080p with bounce count=2.

Older versions would wash out colors in HDR-to-SDR conversions. RTGI 0.17.0.2 corrects the Rec.709 to sRGB conversion matrix, ensuring that ray-traced color bleeding (e.g., green light bouncing off grass onto a stone wall) appears vivid without over-saturation. It is not designed to run on low-end
Released in June 2021, this preset explicitly requires "Marty McFly's RTGI Shader. ReShade GI Beta 0.17.0.2" and offers three variants: a standard color enhancer, an RTGI‑enhanced version, and an RTGI version with custom tonemapping. The creator notes that the preset also works without RTGI, but the RTGI variants deliver substantially better lighting quality.
: Turn off temporal anti-aliasing (TAA) or MSAA inside the game menu, as these techniques often distort the depth buffer. 📊 Performance and Customization Breakdown
| Setting | Recommended start value | Note | |--------|----------------------|------| | | 0.20–0.35 | Larger = farther bounce but more artifacts | | Bounce Count | 2 | 1 for performance, 3+ for quality | | Intensity | 0.6–1.0 | Bounce light brightness | | AO Strength | 0.4 | Ambient occlusion contribution | | Enable specular | On | If game has rough/metal materials | | Temporal accumulation | Off | Not stable in 0.17 – causes ghosting |
