Pascal Gilcher’s RTGI (often called the "Martys Mod" or "Screen Space Ray Tracing") is a shader that simulates and Ambient Occlusion . Unlike simple screen-space ambient occlusion (SSAO), RTGI traces rays in screen space to calculate how light bounces off surfaces. This adds realistic color bleeding (e.g., a red carpet making a white wall slightly pink) and deep shadows, creating volumetric depth that standard rasterization cannot achieve.
: Open the ReShade menu in-game (usually with the Home key) and ensure the "DisplayDepth" shader shows a proper greyscale image. If it doesn't, RTGI will not work correctly. reshade rtgi 0361 full
The "0361" in the phrase referred to a specific build of the ReShade RTGI software, a beta version that had been leaked online. This particular build was said to contain a previously unknown feature, codenamed "Erebus." Rumors swirled that Erebus was an AI-powered rendering engine that could generate entirely new, dynamic environments on the fly. Pascal Gilcher’s RTGI (often called the "Martys Mod"
to find the sweet spot between visual fidelity and his GPU's survival, watching as the "Full" version’s advanced filtering smoothed out the noise until the lighting looked like a high-budget film. : Open the ReShade menu in-game (usually with
RTGI requires access to the game’s "depth map" to know where objects are in 3D space.
