Illuminating Your Library: The ReShade RTGI 0.33 Update The ReShade Ray Traced Global Illumination (RTGI) shader, crafted by Pascal Gilcher (widely known as Marty McFly
), remains the definitive tool for bringing modern lighting to classic titles. Version
represents a significant milestone in this journey, introducing advanced temporal stability and motion-tracking features that bridge the gap between post-process effects and native hardware ray tracing. What is RTGI 0.33?
RTGI is a screen-space ray tracing shader that uses a game's depth buffer to simulate how light bounces off surfaces in real-time. Unlike hardware-level ray tracing (RTX), it is hardware-independent
, meaning it can run on non-RTX cards, including older NVIDIA and AMD hardware. Key Exclusive Features in 0.33
The 0.33 update was a major leap forward, focusing on making the lighting feel "anchored" to the world rather than floating on top of it. Motion Vector Integration: The standout addition to 0.33 is support for motion vectors
. This allows the shader to track object movement between frames, significantly reducing the "ghosting" or trailing artifacts common in previous versions when things moved quickly across the screen. Enhanced Temporal Stability: reshade ray tracing shader rtgi 033 exclusive
By leveraging the new motion data, the shader provides much more stable lighting that resists flickering, a common issue in older screen-space solutions. Improved Specular Reflections:
0.33 refined how the shader handles shiny surfaces, allowing for more accurate light bounces that catch the material properties of the game world. Optimized for ReShade 5.3+:
This version was specifically built to take advantage of the architectural improvements in ReShade 5.3, offering better performance and compatibility. How to Access and Install
Because RTGI is a sophisticated, ongoing project, the latest versions are typically exclusive to Pascal Gilcher’s community supporters. Join the Patreon:
You can access the RTGI 0.33 files by becoming a patron at the Pascal Gilcher Patreon (typically the "Breakfast" or $5 tier). Download & Extract: Once subscribed, you’ll gain access to the PGHub Discord
, where you can download the "ReShade GI Beta" and "Optical Flow/Motion Estimation" archives. Place Shaders: files into your game's reshade-shaders/Shaders folder, and textures into reshade-shaders/Textures Configure Depth: In-game, use the DisplayDepth Illuminating Your Library: The ReShade RTGI 0
shader to ensure your depth buffer is correctly oriented. If it looks like a solid color or inverted, adjust the RESHADE_DEPTH_INPUT_IS_INVERTED setting in the Global Preprocessor Definitions. Performance Consideration
While RTGI 0.33 is highly optimized, it is still a demanding effect. It is recommended to disable in-game Anti-Aliasing (MSAA/SMAA) and Ambient Occlusion (SSAO) to both improve performance and prevent the depth buffer from breaking. specific games that benefit the most from an RTGI upgrade? ReShade 5.3 and RTGI 0.33 Update | August 2022
The RTGI 0.33 update for Pascal Gilcher’s (Marty McFly) ReShade ray tracing shader, released around August 2022, significantly improved performance and visual stability by introducing motion vectors. This version allows for more accurate light bouncing and reduced ghosting in motion compared to older builds. Key Features of RTGI 0.33
Motion Vector Support: The addition of motion vectors allows the shader to track object movement, resulting in much smoother temporal stability and less flickering.
Realistic Global Illumination: Physically simulates how light interacts with the environment, providing realistic indirect lighting and ambient occlusion.
Hardware Independency: Unlike native RTX, this shader operates on depth data, meaning it can run on non-RTX graphics cards (though it remains hardware-demanding). Reduce rays using temporal reuse and importance sampling
Diffuse and Specular GI: Accurately models both soft, scattered light and sharper reflections.
Integration with Launchpad: For 0.33 and later, the iMMERSE Launchpad is required to be at the top of the load order to provide the necessary data for the shader to function.

While the names “Ray Tracing” and “Path Tracing” have become buzzwords for NVIDIA’s RTX series, millions of gamers are still using older GTX cards, AMD Radeon GPUs, or even Intel Arc graphics. Enter the hero of the frame rate: ReShade.
If you have searched for the keyword "ReShade ray tracing shader RTGI 033 exclusive" , you have likely hit a wall of broken links, Patreon paywalls, or outdated GitHub repositories. You are looking for the holy grail of screen-space illumination: the final, optimized, exclusive version 0.33.
This article is your definitive encyclopedia for understanding, acquiring, installing, and optimizing RTGI 0.33. We will cover why this specific version is legendary, where to find the official "exclusive" build, and how to transform games like Skyrim, Cyberpunk 2077 (non-RT mode), GTA V, and Halo Infinite.
The actual exclusive RTGI 0.33 includes three critical files that are hard to find:
RTGI.fx (the main shader)qUINT_rtgi_v0.33.fxh (the core math library)ReShade_Color_Normals.fxh (a helper for precision depth)Note on Legality: Pascal Gilcher has since moved on to a paid "Mortens" version that is closed-source. While distributing the old 0.33 exclusive is technically a violation of his Patreon terms, it is widely archived. You can usually find the untouched exclusive zip file by searching Github Pascal Gilcher RTGI 0.33 release or checking the ReShade Discord’s "archived-shaders" channel.
