Transforming Your Gameplay: The Power of ReShade RTGI 0.36.1
If you’ve ever looked at a classic game and wished it had the moody, dynamic lighting of a modern blockbuster, ReShade RTGI 0.36.1 is the bridge you’ve been looking for. Created by Pascal Gilcher (popularly known as Marty McFly), this Ray Traced Global Illumination (RTGI) shader allows almost any PC game to simulate sophisticated lighting effects that were once the exclusive domain of high-end, native ray-tracing titles.
Version 0.36.1 represents a critical sweet spot in the shader's history, balancing the advanced features introduced in the 0.3x branch with a level of stability that makes it a favorite for many modders. What Makes RTGI 0.36.1 Special?
Unlike native ray tracing, which requires specific hardware like NVIDIA's RTX or AMD's 6000-series cards, RTGI is hardware independent. It works by using "screen-space" data—specifically the depth buffer—to calculate how light should bounce off surfaces in your current view. Key Features of the 0.36.1 Era:
Diffuse and Specular GI: It models both the soft glow of light reflecting off matte surfaces (diffuse) and the sharper reflections on shiny objects (specular).
Farplane Optimization: This version is known for its specific "Farplane" tuning. Users often recommend setting the farplane value to 2500 for optimal results, ensuring the lighting effects extend naturally into the distance without cutting off abruptly.
Temporal Stability: Compared to earlier versions, 0.36.1 offers improved stability, meaning you'll see less of the "flickering" or noise that can sometimes plague post-processing shaders.
Sky Color Integration: It includes "Sky Color" tweaking, allowing you to fake out-of-screen luminosity to make the lighting feel more integrated with the game's atmosphere. Installation and Setup Guide
To get RTGI 0.36.1 running, you’ll need a standard installation of ReShade (the universal injector). reshade rtgi 0361
It seems you're referring to ReShade RTGI (Ray Traced Global Illumination) by Pascal Gilcher (also known as Marty McFly), specifically version 0.361 or a variant of the shader with a build identifier like 0361.
Here's what you likely need to know:
To understand why RTGI 0361 is so impactful, we have to understand what it replaces. Traditional game rendering relies on Rasterization. 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.
What rasterization fails to capture is bounce light. In the real world, if you shine a flashlight on a red carpet next to a white wall, the wall glows red. The light bounces. In traditional games? The wall stays white. The carpet stays red. They exist in isolation.
This is why games often feel "gamey" or artificial. They lack the cohesion of light traveling through an environment.
Unlike native ray tracing, which uses geometry data from the engine (buffers), ReShade RTGI is a post-process effect. It has no access to the game's internal 3D world. It only sees what you see: a flat, 2D image. Version 0.3.6.1 perfected the art of lying convincingly.
The shader works by analyzing the depth buffer (how far away pixels are) and the color buffer (what color those pixels are). It then injects a coarse grid of rays into this 2D projection. When you move your camera, those rays recalculate, creating the "boiling" or "noisy" artifact that RTGI is famous for. Yet, when you stand still, the accumulation buffer kicks in, smoothing the noise into a soft, volumetric glow.
Why is 0.3.6.1 special? Because it represents the apex of "good enough." Later versions introduced temporal stability (reducing the boil), but they also introduced a clinical sterility. Version 0.3.6.1 retains a certain analog warmth. The noise looks less like a rendering error and more like film grain. It embraces its imperfection.
ReShade RTGI (Ray Traced Global Illumination) by Pascal Gilcher (alias "Marty McFly") represents a watershed moment in post-processing graphics. Unlike native Ray Tracing (DXR) implemented in game engines like Cyberpunk 2077 or Control, which relies on dedicated hardware cores (RT cores) and deep engine integration, RTGI is a shader-based approximation. It runs via ReShade, a generic post-processing injector.
Version 0.361 is often cited as a "gold standard" or a highly stable milestone in the shader's development lifecycle, balancing accuracy with performance before later, more experimental iterations. If you want, I can:
RTGI does not have access to the game's actual geometric data or scene graph. It only sees a 2D image and a Z-Buffer (depth map).
Reshade RTGI 0361 is more than a graphical tweak; it is a statement. It proves that lighting is the soul of visual fidelity. It allows gamers on a budget to experience a slice of next-generation lighting technology in titles that were abandoned by developers years ago.
Yes, it costs frames. Yes, it requires tweaking. But the moment you see a sunset in The Witcher 3 actually turning the interior of a wooden cabin a dusty orange through the windows, you realize the cost was worth it. You aren't just playing the game anymore; you are seeing the light the developers intended, but could never afford to render.
In the context of the ReShade RTGI 0.36.1 shader, "deep piece" likely refers to the Depth Buffer
(Z-buffer), which is the critical component required for the Ray Traced Global Illumination (RTGI) effect to function. marty's mods
RTGI uses the depth buffer to calculate how light rays bounce off objects in 3D space. If this "piece" of the rendering process is not correctly configured, the shader will not apply correctly, often resulting in no visible effect or lighting that "flickers" through menus. marty's mods Troubleshooting the "Deep Piece" (Depth Buffer)
To ensure the depth buffer is working for RTGI 0.36.1, check the following in your ReShade menu: Enable Generic Depth : Go to the tab and ensure the Generic Depth add-on is checked. Select the Correct Buffer
: Under the Generic Depth settings, you will see several depth buffers listed. Select the one that matches your game's resolution and shows the most "movement" when you move your character. Check Preprocessor Definitions
: If the lighting looks upside down or reversed, you must edit the Global Preprocessor Definitions RESHADE_DEPTH_INPUT_IS_REVERSED (or vice versa). RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN if the image appears inverted. Display Depth Shader : To verify what ReShade sees, enable the DisplayDepth.fx
shader. If you see a solid black or white screen, the depth buffer is not being captured, often due to in-game Anti-Aliasing (MSAA) or being in an online game where depth is disabled to prevent cheating. marty's mods for a particular game?

The ReShade RTGI 0.36.1 refers to a specific legacy version of the Ray Traced Global Illumination (RTGI) shader developed by Pascal Gilcher, also known as Marty McFly. This shader is a post-processing tool that introduces ray-traced lighting and shadows into video games that do not natively support them. Overview of RTGI 0.36.1
In the development timeline of RTGI, version 0.36.1 represents an early stage of the shader's evolution. RTGI functions by utilizing a game's "depth buffer" to calculate how light should realistically bounce off surfaces and cast soft shadows within the player's field of view. Key Features and Mechanics
Screen-Space Ray Tracing: Unlike hardware-accelerated ray tracing (found in RTX cards), RTGI is "screen-space". It only calculates lighting for objects currently visible on your screen, meaning it cannot account for light sources or objects behind the camera or off-screen.
Global Illumination (GI): This simulates the physical behavior of light, allowing it to "bounce." For example, if light hits a red floor, it will subtly reflect a red tint onto the surrounding walls.
Ambient Occlusion: It provides highly accurate contact shadows in corners and crevices, adding depth and "weight" to 3D objects.
Hardware Independence: One of the most significant aspects of this version is that it does not require an NVIDIA RTX or AMD RX 6000-series card. It runs on any hardware capable of supporting ReShade, though it is computationally demanding. Performance and Setup
Impact: Version 0.36.1 was known for being a heavy "beta" version. Activating it typically results in a significant drop in frame rate, often 30-50% depending on the complexity of the scene.
Prerequisites: To use it, users must have ReShade installed and ensure the game's depth buffer is correctly accessed (often requiring the disabling of in-game Anti-Aliasing).
Availability: Most versions of RTGI, including early ones like 0.36.1, were primarily distributed through the creator's Patreon.
While newer versions (such as 0.5x or 0.7x) have since introduced features like restir (for more light sources) and improved temporal stability, version 0.36.1 remains a milestone for bringing "next-gen" lighting to older titles.
When moving the camera quickly, you might see a trail of light behind characters.
