RTGI requires depth data to "see" where objects are in 3D space.
, is a post-processing tool developed by Pascal Gilcher (also known as Marty McFly). It simulates ray-traced lighting effects in games that do not natively support them by using the screen's depth buffer. Key Features of RTGI 0.33 Motion Vectors Support
ReShade RTGI (Ray Traced Global Illumination) shader, specifically version
: Unlike native hardware ray tracing (RTX), which calculates light based on an entire 3D scene, RTGI is a screen-space effect reshade ray tracing shader rtgi 033
To use RTGI 0.33, you must install the base ReShade program first, then manually add the premium RTGI shader files. Step 1: Install ReShade
Before diving into the specifics of RTGI 0.33, it helps to understand the underlying framework: ReShade. ReShade is an open-source post‑processing injector that sits between a game’s renderer and your display, allowing you to apply custom shader effects after the game has finished its rendering pass. Because it works in the post‑processing stage, ReShade can enhance lighting, add depth of field, apply colour grading, and more—without modifying the game’s original assets or requiring deep engine access.
Works seamlessly across DirectX 9, DirectX 11, DirectX 12, and Vulkan. RTGI requires depth data to "see" where objects

RTGI 0.33 can cut your framerate by 20% to 50% depending on your configuration. Use these optimization configurations to reclaim performance:
Screen-space ray tracing has revolutionized PC gaming graphics. Pascal Gilcher’s shader for ReShade brings path-traced lighting, ambient occlusion, and physical reflections to almost any 3D game. Version 0.33 introduces critical performance optimizations and image quality adjustments. This comprehensive guide covers how ReShade RTGI 0.33 works, how to install it, and how to optimize your settings for the perfect balance of visual fidelity and framerate. What is ReShade RTGI 0.33? Key Features of RTGI 0
Version 0.33 enhances micro-shadowing. It fills in the gaps that traditional ambient occlusion misses, such as the tiny spaces beneath a character's boots, intricate armor folds, or individual blades of grass. It grounds objects into the world, removing the "floating" effect common in older 3D titles. 3. Advanced Denoising Infrastructure
It is important to understand the limitations of ReShade RTGI v0.33. Unlike native DXR (DirectX Raytracing) or Vulkan Ray Tracing, which have access to the full 3D geometry of the scene, ReShade only sees what is on the screen (the 2D image and depth buffer).
