Drastically cuts down the visual "noise" or grain common in early ray tracing shaders. Prerequisites and Requirements
Place any associated texture files in the Textures folder if required. Step 3: Activating in Game Launch your game. Press the key to open the ReShade menu. Check the box for McFlyRTGI.fx . Optimizing RTGI for Performance and Quality
Determines how far light can bounce. A lower value is faster and often sufficient.
: Controls the accuracy of the lighting. Higher values reduce noise but decrease performance. reshade rtgi 0361 full
The RTGI 0.36.1 shader by Pascal Gilcher brings path-traced lighting, ambient occlusion, and advanced bounce lighting to PC games. This version focuses on refined, flicker-free denoising and efficient, realistic lighting, available exclusively through the developer's Patreon page.

Created by (Marty McFly), the RTGI shader brings Real-Time Ray Traced Global Illumination to almost any game that allows ReShade. Unlike standard lighting, it simulates how light bounces off surfaces, fills shadows, and adds realistic "color bleed" from bright objects onto nearby walls. Key Features of v0.36.1
Follow these steps to install ReShade and integrate the RTGI 0.36.1 Full shader pack. Step 1: Download and Install ReShade Drastically cuts down the visual "noise" or grain
Simulates light bouncing multiple times to prevent unnaturally dark corners.
: Tells the shader how thick objects are in screen space. Tweak this to prevent light from bleeding through thin walls.
This version is a Screen Space Ray Tracing shader. Unlike hardware-accelerated ray tracing (RTX), which uses the entire 3D scene data, RTGI uses "screen space" information—meaning it only calculates lighting for objects currently visible on your screen. Press the key to open the ReShade menu
The shader is a post-processing tool developed by Pascal Gilcher (also known as Marty McFly) that adds Ray-Traced Global Illumination (RTGI) to almost any 3D game. By utilizing screen-space data and a game’s depth buffer, this shader simulates how light bounces off surfaces, bringing modern, realistic lighting to older titles and enhancing the visual fidelity of newer ones without requiring dedicated ray-tracing hardware.

This comprehensive guide explores what ReShade RTGI 0.36.1 is, how it functions, the performance impacts to expect, and how to set it up safely. What is ReShade RTGI?
For gamers looking for a genuine leap in lighting realism without waiting for game developers to patch in official ray tracing, is a powerful gateway. While newer versions exist, the "0361 Full" configuration represents a specific moment in post-processing history where performance, compatibility, and visual quality aligned perfectly. By following this guide—installing ReShade, manually adding the qUINT_RTGI shader, tuning the "Full Rate" settings, and troubleshooting the depth buffer—you can finally unlock dynamic, realistic global illumination in your favorite classic titles.
