While true multi-bounce ray tracing is too heavy for real-time post-processing, RTGI 0.36.1 uses clever mathematical approximations to simulate the soft, ambient scattering of secondary light.
This is often a shader compilation error or a missing texture file. Solution: Reload all shaders from the ReShade overlay. If the problem persists, re-copy the Textures folder from your 0.36.1.zip file into the game's reshade-shaders/Textures folder.
Turn up the Denoise Filter Strength or slightly increase the Ray Amount . Ensure your frame rate is stable, as the temporal denoiser requires consistent frame data to clean up the image.
To understand why RTGI 0361 is so impactful, we have to understand what it replaces. Traditional game rendering relies on . In a rasterized world, an object exists, and a light source hits it. The engine calculates how bright that object should be based on the direct line of sight to the light.
Expect a performance hit ranging from 15% to 30%, depending on your resolution and GPU architecture. Running the shader at 4K resolution requires a robust, modern graphics card. The Verdict: Is It Worth It? reshade rtgi 0361
represents a stable, mature iteration of the shader. While newer versions exist (often behind Pascal Gilcher's Patreon), 0.36.1 is frequently cited in community presets for its balance of visual fidelity and compatibility with the main ReShade platform Performance and Technical Realities GPU Intensity:
In the fast-paced world of PC gaming graphics, achieving realistic lighting has long been the holy grail. While modern ray tracing (DXR) offers true-to-life reflections and global illumination, it requires cutting-edge hardware and specific game support. Enter Marty McFly's ReShade RTGI, a revolutionary shader that brings ray-traced global illumination to nearly any game via ReShade. Specifically, represents a significant milestone in this development, offering a matured, highly functional version of this "screen-space" ray-tracing technique.
To use RTGI 0.36.1, you typically need to be a supporter of Marty's Mods on Patreon, as the shader is part of a paid early-access program. Tuning the RTGI ReShade shader, with settings explained
Select the appropriate rendering API (DirectX 11, DirectX 12, or Vulkan). While true multi-bounce ray tracing is too heavy
While NVIDIA and AMD battle it out with expensive hardware ray tracing cores, a quiet revolution has been happening in the modding scene. Specifically, the release of (Pascal Gilcher’s Ray Traced Global Illumination shader) represents a pivotal moment in how we perceive virtual worlds.
Understanding ReShade RTGI 0.36.1: The Ultimate Ray Tracing Upgrade for Older Games
: ReShade extracts a grayscale map from the engine indicating exactly how far each object is from the camera lens.
Extract the RTGI 0.36.1 files. Copy the contents of the Shaders folder into your game's reshade-shaders/Shaders directory, and the Textures into reshade-shaders/Textures . If the problem persists, re-copy the Textures folder
The shader calculates where geometry meets (such as corners, cracks, and crevices) and applies realistic, soft contact shadows.
It casts virtual rays of light across this depth data to calculate how light should bounce from one surface onto another.
This happens because screen-space shaders cannot "see" objects hidden behind other objects. Adjust the Z-Thickness slider in the RTGI settings to tell the shader how thick virtual walls should be.
