, 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

Before unpacking the specifics of version 0.33, it’s essential to understand the core technology. RTGI (Ray Traced Global Illumination) is a post‑processing shader for ReShade—an open‑source tool that allows custom shaders to be injected into almost any DirectX 9–12, Vulkan, or OpenGL game. Unlike the hardware‑accelerated ray tracing found in native RTX implementations, RTGI works entirely in using a technique known as SSRTGI (Screen‑Space Ray Traced Global Illumination).

Real-time ray tracing calculates the path of light particles (photons) from a source to your eye. True hardware ray tracing (RTX) does this using dedicated cores. does not do that.

The free version on GitHub (often labeled ReShade_Private_RTGI_v0.33 ) is usually the "Lite" variant. It lacks the ability to write to the normal buffer, leading to light bleeding through walls.

. Created by legendary rendering engineer and mathematician Pascal Gilcher (popularly known as "Marty McFly" ), this particular milestone build leverages advanced screen-space ray marching and depth-buffer analysis. By doing so, it introduces physically simulated ambient occlusion, indirect lighting bounces, and rich color bleeding without requiring native engine integration or dedicated hardware RT cores. 🚀 The Core Breakthrough of RTGI 0.33

: While it works on non-RTX cards by using depth buffer data, it is highly demanding.

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?
