Unlike native RTX, this shader operates on depth data , meaning it can run on non-RTX graphics cards (though it remains hardware-demanding).
This guide is for educational and archival purposes. Version 0.33 is obsolete (replaced by newer RTGI and then by Marty’s Screen Space Ray Tracing ). It is also closed-source/Patreon-era software. reshade ray tracing shader rtgi 033 exclusive
, meaning it only calculates light based on what is currently visible on your monitor and the game's depth buffer. Unlike native RTX, this shader operates on depth
The primary appeal of RTGI v0.33 lies in its ability to fundamentally alter the atmosphere of a scene. In standard rendering, shadows are often stark and black, lacking nuance. This is known as the "void" effect, where unlit areas feel artificially dark. RTGI addresses this by simulating light bounce. It is also closed-source/Patreon-era software
The update, released in August 2022 by Pascal Gilcher (also known as Marty McFly), introduced significant technical advancements to the Ray Traced Global Illumination shader, most notably the integration of motion vectors . Key Features of RTGI 0.33
