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).
To understand why version 0.361 is significant, one must understand the technical hurdles it overcomes. The shader operates on the G-Buffer (Geometry Buffer) generated by ReShade’s depth pre-pass.
Software rot is real. Newer drivers break old shaders. Windows updates cause flickering. Yet, the community maintains a simple mantra: If it works, don't update it.
Version 0.3.6.1 endures because it represents the last moment of pure, non-commercial experimentation in real-time lighting. It is messy. It boils. It ghosts. But it also turns the flat, matte textures of Skyrim into a living diorama. It gives Dead Space a tangible dread.
Marty McFly has since moved on to a paid, closed-source model. That is his right. But in doing so, he accidentally froze a masterpiece in amber. RTGI 0.3.6.1 is the ghost in the raster—a piece of software that proves light doesn't need to be perfect to be beautiful. It just needs to bounce.
Final Verdict: Install it on an old RPG. Turn off the HUD. Walk through a forest at sunset. Watch the green leaves cast a subtle green tint onto your character's white armor. That interaction—that unintended consequence of a post-process hack—is the most magical thing real-time graphics have ever produced.
ReShade RTGI (Ray-Traced Global Illumination) , specifically version , is a highly regarded post-processing shader developed by Marty Stratton
(Pascal Gilcher). It is designed to simulate ray-traced lighting effects in games that do not natively support them by using the game's "depth buffer" to calculate how light should bounce off surfaces. Core Features & Visual Impact Global Illumination (GI):
This is the standout feature. It calculates light bounces, allowing colors from a bright surface (like a neon sign) to "bleed" onto surrounding objects and walls. Ambient Occlusion (AO):
It provides superior shadowing in crevices and corners compared to standard in-game solutions like SSAO, adding significant depth and "grounding" to objects. Versatility: reshade rtgi 0361
Since it is a ReShade shader, it can be injected into almost any DX9, DX11, DX12, or Vulkan game, including older titles like The "0.36.1" Context
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:
RTGI is significantly more demanding than standard ReShade filters like color correction or sharpening. Users should expect a noticeable drop in frame rates (FPS). Depth Buffer Requirement:
For RTGI to work, the game must provide access to its depth buffer. In some online/multiplayer games, ReShade disables this access to prevent cheating, which renders RTGI non-functional. Screen-Space Limitations:
Because it only knows what is currently on your screen, light from "behind" the camera or behind objects cannot be calculated. This can lead to occasional "flickering" or light disappearing at the edges of the screen. For single-player gaming, RTGI 0.36.1
is a "must-try" for enthusiasts with capable hardware. It can transform the atmosphere of a game, making environments feel more cohesive and realistic. However, it requires manual setup—including configuring Global Preprocessor Definitions to ensure the depth buffer is oriented correctly. marty's mods Portal Reshade RTGI - The Working Class' RTX Portal
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? RTGI does not have access to the game's
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 0.36.1 is a specific older version of the Ray Traced Global Illumination
shader, a popular post-processing mod created by Pascal Gilcher (also known as Marty McFly). It simulates real-time ray-traced lighting, shadows, and color bounce in video games that do not natively support these features. marty's mods Core Technology: Screen Space Ray Tracing
Unlike "native" ray tracing, which calculates light hitting all objects in a 3D scene, ReShade RTGI is a screen-space effect . It uses the game's depth buffer First, let’s clarify the terminology
to "see" the geometry visible on your monitor and shoots rays from those pixels to calculate how light should bounce and where shadows (Ambient Occlusion) should fall.
: It significantly improves the depth and realism of lighting in older titles like Guild Wars 2 Limitation
: Since it only knows what is on your screen, objects behind the camera or hidden behind other objects cannot cast shadows or reflect light. Version 0.36.1 and Development Context
First, let’s clarify the terminology. RTGI is not a full ray-tracing implementation like NVIDIA’s RTX. Instead, it is a post-processing effect that analyzes the depth buffer and screen-space data to approximate how light bounces off surfaces. Version 0361 sits in a specific historical sweet spot: it was released after the major "next-gen" refactor but before the transition to the newer, more demanding "Radiance" UI.
Key features of version 0361 include:
Reshade RTGI works by injecting a compute shader into your game’s rendering pipeline. It utilizes your GPU (preferably NVIDIA, given the architecture, though AMD support is viable) to perform ray tracing calculations.
However, there is a catch. Unlike native hardware ray tracing (RTX), which traces rays through the full 3D geometry of the scene, Reshade RTGI is a Screen-Space effect. It only knows what the camera sees.
Version 0361 is significant because it optimizes this screen-space limitation. It takes the depth buffer and color buffer of your game and traces rays from every pixel to determine how light should bleed onto it.
In the world of PC gaming, graphical fidelity is a never-ending race. While game engines get smarter every year, the hardware requirements often leave older or less optimized titles in the dust. Enter ReShade RTGI (Ray Traced Global Illumination) —a screen-space shader that simulates realistic light bouncing. Among the many iterations released by developer Pascal "Marty McFly" Gilcher, version 0361 has emerged as a landmark build. But what makes ReShade RTGI 0361 so special? Is it stable? Is it worth the performance hit?
