is a highly popular post-processing shader developed by Pascal Gilcher (Marty McFly) . It uses a technique called Screen Space Ray Tracing to simulate how light bounces off surfaces, adding realistic lighting, shadows, and color bleeding to games that do not natively support Ray Tracing. reshade ray tracing shader rtgi 033
RTGI stands for . In traditional game rendering (rasterization), lighting is often "baked" into the textures or simulated via pre-placed light sources that don't naturally bounce. A light source illuminates a wall, but the light doesn't bounce off that wall to illuminate the floor.
: This is the headline feature for version 0.33. By utilizing motion vectors, the shader can track pixel movement between frames, significantly reducing "ghosting" or trailing artifacts common in previous versions. Extract the Shaders and Textures from the RTGI
, version 0.33 is often cited in community guides for its stability and specific feature set: Infinite Bounces
Once this reconstruction is built, RTGI 0.33 performs a "path tracing" simulation on this screen-space data. Because it has no access to geometry outside your current field of view, RTGI must make intelligent estimates for occluded areas and surfaces that are hidden from the camera. While this approach has limitations, Gilcher's algorithm used a proprietary method distinct from the earlier, more popular ReSTIR GI technique, aiming to maintain high visual fidelity even while relying on limited data. By version 0.33, the technology had proven itself capable of generating temporally stable lighting, minimizing the distracting flickering that often plagued other screen-space solutions. It uses a technique called Screen Space Ray
: Better detection of object depth, which prevents light from "leaking" through thin walls or character models.
Running the shader at half-rate resolution drastically improves performance while the temporal filter keeps the lighting looking sharp.
