The year 2021 was a transformative era for PC gaming graphics, largely due to the widespread adoption of the ReShade Ray Traced Global Illumination (RTGI) shader. Developed by Pascal Gilcher (also known as Marty McFly), the represented a pinnacle of post-processing technology, allowing gamers to inject sophisticated lighting effects into almost any title—even those released long before the hardware ray tracing era. What is the RTGI Shader?
Minimized flickering and lag, providing a smoother visual experience compared to earlier versions.
Improved algorithms to reduce the "noise" often associated with ray tracing, leading to a cleaner image. reshade ray tracing shader rtgi 033 2021
Adds realistic shadow casting and material interaction that adapts to the in-game environment.
ReShade Ray Tracing: Unlocking Next-Gen Visuals with RTGI 0.33 (2021) The year 2021 was a transformative era for
Best used with the "Launchpad" pre-pass shader, which provides motion estimation using optical flow for more precise lighting updates.
Using RTGI requires a standard ReShade installation and access to Pascal Gilcher's shader files. Minimized flickering and lag, providing a smoother visual
One of the most significant updates in the 0.33 release was the addition of motion vectors, which drastically improved the accuracy of lighting during fast movement. Key Features of Version 0.33 (2021)
Accurate modeling of both diffuse and specular light, ensuring that shiny surfaces reflect the environment correctly. How to Install and Optimize RTGI 0.33
The ReShade RTGI shader is a post-processing effect that simulates . Unlike traditional baked lighting, RTGI facilitates real-time interactive "bounce lighting," where light reflects off surfaces to illuminate areas not directly hit by a primary light source. Key benefits of the 0.33 version include:
