Pascal Gilcher provides new versions of RTGI (like v0.33 at the time) on a "donation-wall" basis. Specifically, the "beta" tier on his Patreon page is set at a minimum of .
To legally obtain the RTGI shader (including older builds like 0.33 or the current 0.36+ versions), you must:
ReShade RTGI (Ray Traced Global Illumination) shader, specifically version , is a sophisticated post-processing tool created by Pascal Gilcher
Features an intuitive interface with quality presets for both diffuse and specular GI, allowing users to balance visual quality against performance costs. marty's mods "Free" vs. Paid Access Paid Access (Patreon):

⚠️ Avoid shady “RTGI 0.33 free download” sites — they often bundle malware. Use GitHub or official ReShade Discord.
Imagine a room. Native RT can tell you how light bounces off the ceiling, the floor, and the walls behind you. RTGI can only tell you how light bounces off what you see through a window from one angle. However, for many static scenes and indirect lighting, RTGI's approximation is remarkably effective and often a massive improvement over a game's native lighting.
: It does not require an RTX card, making it compatible with older hardware as long as they can handle the performance cost. reshade ray tracing shader rtgi 033 free
Unlike "true" ray tracing, it can only trace objects currently visible on your screen.

The RTGI shader is officially a paid mod hosted on Pascal Gilcher’s Patreon page.Developing screen-space ray tracing algorithms requires massive amounts of time and updates. Official Access Pascal Gilcher provides new versions of RTGI (like v0
Copy any accompanying texture or header files ( .fxh ) into reshade-shaders\Textures or Shaders as specified by the readme file. Step 3: Configure the Depth Buffer
The technology relies on a method called , where the shader simulates the paths of millions of light rays per frame. While this is incredibly demanding, RTGI is optimized to run efficiently using a screen-space approach, calculating light bounces in real-time directly from what your monitor displays.
(also known as "Marty McFly"). While ReShade itself is free, the RTGI shader is typically distributed through a paid model, though a "free" version of the technology exists in a limited capacity. Key Features of RTGI 0.33
