The centerpiece of update 0.36.1 is Gilcher's decision to abandon a widely respected industry algorithm in favor of his own creation. Originally, he tried to implement NVIDIA's ReSTIR GI algorithm into his shader, but he encountered significant and persistent issues. These included "chroma noise" (because the reservoir sampling method could only hold light from a single direction), sample correlation problems that broke the denoiser's variance estimation, and an unstable white noise output.
Because everything works from depth data only, RTGI does not read full material properties (roughness, metalness, albedo). In practice, the visual effect is still impressive, though a few limitations remain—more on that in the limitations section.
Turn on to smooth out graininess during camera movement.
: Dictates how far light travels before fading. Higher values create larger, softer shadows but can cause light leaks through thin walls. 2. Temporal Filtering (The Secret to Smooth Performance) Reshade Rtgi 0.36.1
Reshade is a post-processing injector that can be used to enhance the graphics of games and other applications. It works by injecting shaders into the rendering pipeline, allowing for a wide range of visual effects to be applied. RTGI, or Real-Time Global Illumination, is a technology that simulates the way light interacts with objects in a scene. It calculates how light bounces off surfaces, creating more realistic and dynamic lighting conditions. When combined, Reshade RTGI offers users the ability to experience advanced lighting effects in games and applications that may not natively support RTGI or similar technologies.

RTGI 0.36.1 works well alongside:
: Move the qquint_rtgi.fx file above your game UI shaders in the ReShade list, or use a specialized UI mask add-on.
RTGI (Ray Traced Global Illumination) is a post-processing shader that adds dynamic, realistic lighting to games by simulating how light bounches off surfaces. Unlike native RTX, it uses . It relies on the game’s "depth buffer" to understand the 3D layout of a scene and calculate indirect lighting and ambient occlusion. Key Features in Version 0.36.1
: Increase the temporal blending factor or slightly lower the ray amount to let the engine refresh cache frames faster. The centerpiece of update 0
Check the DisplayDepth shader to ensure your depth buffer is loading correctly.
Simulates light bouncing off surfaces to illuminate surroundings realistically.
Ray tracing is computationally expensive. Evaluations indicate: Because everything works from depth data only, RTGI
It adds "color bleeding," where light hitting a colored object (like a red wall) naturally reflects that color onto surrounding surfaces. How to Install Reshade RTGI 0.36.1
