Dictates how many rays are cast per pixel. Increase this to reduce noise, but be prepared for a performance hit.
Since 0.33, the RTGI shader has undergone numerous major updates. Version (released in 2024) introduced sky color ray tracing , significant performance improvements, and the ability to disable diffuse or specular GI independently. More recently, Gilcher claimed to have implemented a new sampling algorithm that outperforms ReSTIR GI in quality and added pixel‑perfect path‑traced reflections using HiZ Min‑Max Tracing.
The , created by Pascal Gilcher (also known as Marty McFly), is a highly advanced screen-space ray tracing tool that adds dynamic global illumination (GI) and ambient occlusion (AO) to almost any 3D game. While RTGI has since moved to newer versions like 0.70, version 0.33 remains a landmark release for its specific feature set and widespread adoption in various mod presets.

If you downloaded a preset that is configured for RTGI 0.33, simply copy the provided .ini file into the same directory as your game's executable. When you launch the game, the preset should be applied automatically. If not, press the "Home" or "Del" key (by default) to open the ReShade UI in-game and manually select the preset.
Users could better customize ray depth, step length, and sample count to balance the cinematic look with their GPU's capability. How RTGI 0.33 Works Dictates how many rays are cast per pixel
shader to ensure your depth buffer is correctly oriented. If it looks like a solid color or inverted, adjust the RESHADE_DEPTH_INPUT_IS_INVERTED setting in the Global Preprocessor Definitions. Performance Consideration
The exclusive nature has both practical and ethical dimensions. On one hand, it ensures that Gilcher receives funding to continue his research into advanced real‑time rendering—work that benefits the entire PC gaming community. On the other hand, it has led to a fragmented ecosystem where new users are sometimes confused about how to obtain the shader legally. Official sources always point to and the Raytracers tier (often priced around $5 per month) as the legitimate way to get RTGI. Version (released in 2024) introduced sky color ray
If you are experiencing flickering or noisy visuals, try enabling "Motion Vectors" if your preset supports it. This helps stabilize the temporal accumulation of rays frame-to-frame. You can also check if you have the correct _MARTYSMODS_TAAU_SCALE preprocessor defined if using upscalers.

Known as "true" ray tracing, this calculates all light paths in real-time, often leading to better reflections and shadows.
RTGI reads the game's depth buffer to understand the 3D structure of the scene.
