(with further refinements reaching version 0.33 by August 2022). It is a screen-space post-processing effect that simulates ray-traced lighting and shadows by using a game's depth buffer. Key Features of RTGI 0.33 Motion Vectors Support:
Because it was purely screen-space, anything off-screen (e.g., a bright light behind the camera) couldn’t contribute – a known limitation. Yet, for first-person games where the camera moves often, the effect felt surprisingly natural. reshade ray tracing shader rtgi 033 2021

The shader is designed to work with a wide array of games, especially those that might not natively support ray tracing or are limited by their rendering engines. Its compatibility is largely dependent on the ReShade framework, which supports DirectX 9, 10, 11, and 12, as well as Vulkan.
This report evaluates the , released in 2021 by developer Pascal "Marty McFly" Gilcher. Unlike hardware-accelerated ray tracing (DirectX Raytracing – DXR), this shader implements a screen-space ray marching algorithm within the ReShade post-processing framework.
