Once the depth buffer works correctly:
Using RTGI 0.33 comes with significant performance considerations: FPS Impact : Users typically see a 25% to 50% drop in frame rate depending on settings and resolution. Hardware Agnostic : Unlike Nvidia’s RTX, this shader works on any graphics card
Better calculation of secondary light bounces for more realistic color bleeding. Hardware and Software Requirements
You will need the latest version of ReShade installed to your target game's executable directory. How to Install and Set Up RTGI 0.33 reshade ray tracing shader rtgi 033
If you encounter a preset that requires “RTGI 0.33 or newer,” the preset author usually provides only the configuration (.ini) file; you must still supply the RTGI shader yourself from Patreon.
Version 0.33 represents a highly stable, mature release of the shader. It focuses on:
The ReShade Ray Tracing Shader RTGI 0.3.3 is a highly optimized, ray-tracing-based implementation of RTGI, designed to work seamlessly with a wide range of applications. Here are some key features and technical highlights:
RTGI v0.33 is perfect for:
: It provides much deeper and more accurate shadows in corners and crevices compared to traditional methods like SSAO or HBAO. Material Interaction

RTGI 0.33 introduced better detection of scene depth across different rendering APIs (DirectX 11/12 and Vulkan). Games that previously required extensive manual tweaking now accepted the shader with minimal configuration. The improvements also laid the groundwork for the “Copy depth buffer before clear operations” workaround that solves black‑screen issues in many titles. | Limitation | RTGI 0
So, what exactly is ray tracing, and how does it enable the creation of such realistic visuals? In traditional rasterization-based rendering, the GPU approximates the final image by projecting 3D geometry onto a 2D screen. Ray tracing, on the other hand, works by simulating the way light behaves in the real world, casting virtual "rays" into the scene to determine how they interact with objects.
: Typically used with ReShade 5.3 or newer to leverage the full feature set of 0.33.
: Since the shader acts on the final image, it can sometimes accidentally "ray trace" the game's user interface (HUD), causing menus or maps to look blurry or shadowed.
