The shader casts rays from the camera and light sources across this map.
When a ray hits an object, it calculates the color of that object and "bounces" that color onto nearby surfaces.
The RTGI shader is a product of intensive independent research and development. It is typically distributed through , making the specific 0.33 build part of an "exclusive" tier of early-access software. This support model has allowed the shader to evolve from a niche experiment into a tool used by digital photographers and "ultra-modded" gameplay enthusiasts globally. Conclusion
Improved precision in how light rays interact with the geometry provided by the game's depth map.
While true infinite bounces are impossible for a post-process shader, 0.33 uses clever approximation to simulate secondary light bounces, giving interiors a much warmer, more realistic glow. How it Works: The ReShade Integration
RTGI 0.33 doesn't modify the game's code; instead, it hooks into the framework. It utilizes the Depth Buffer —the 3D data the GPU uses to determine what is in front of what—to cast rays. Depth Access: ReShade captures the 3D "map" of the scene.
Running RTGI 0.33 is demanding. Because it is a software-based ray tracing solution, it relies heavily on your GPU's raw compute power.
This build includes improved logic for estimating the thickness of objects, preventing light from "leaking" through walls or thin surfaces—a common issue in earlier screen-space ray tracing versions.
