Developed by Pascal Gilcher, popularly known as "Marty McFly", this post-processing mod injects real-time light bounces, realistic ambient occlusion, and physical shadows into almost any 3D game engine.
Notable examples include:
Version 0.33 handles edge detection beautifully. Older versions often caused a dark halo or "glow" effect around a game's User Interface (UI) or character models. The new build introduces smarter depth filtering, ensuring that shadows hug geometry precisely without clipping through foreground objects. 4. Improved Performance Scaling reshade ray tracing shader rtgi 033 exclusive
Traditional hardware ray tracing calculates rays against the entire 3D polygon geometry of a game scene, whether it is visible on screen or hidden around a corner. ReShade RTGI utilizes a advanced process called . It shoots mathematical rays through the Z-buffer (depth buffer) and color information actively rendered on your monitor. Global Illumination and Light Bouncing
While RTGI works on almost any game with a depth buffer, certain engines benefit massively from injected global illumination. Developed by Pascal Gilcher, popularly known as "Marty
: Keep between 8 and 12 to prevent distant objects from causing stutter.

UI Bleeding: The shader can sometimes accidentally apply lighting calculations over text menus and maps.
So why is version still so widely referenced? At the time of its release, RTGI was already mature, but 0.33 introduced a series of refinements that made it the go‑to version for many preset creators and users. The shader was no longer an early beta—it had become stable, performant, and compatible with a broad range of titles.
Because RTGI 0.33 calculates thousands of light rays per frame, it demands decent hardware. However, because it is a screen-space effect, it . System Requirements
