Because it only calculates what is currently visible on your screen, RTGI is vastly more efficient than native ray tracing, allowing older hardware to experience next-generation lighting physics. What’s New in RTGI Version 0.36.1?
This version, specifically, hit the sweet spot of performance-to-quality. Turning the "Ray Length" to medium and "AO Strength" to 0.3 provides 90% of the visual benefit of native ray tracing at 50% of the performance cost of modern AAA implementations.
Controls the precision of the calculation. Increase this if the lighting looks patchy or grainy.
Unlike screen-space techniques (like SSAO) that only darken corners, RTGI 0.36.1 computes actual rays to determine how light travels from a source, hits surfaces, and illuminates dark areas. As of late 2025/early 2026, the technology has evolved toward spectral rendering to improve saturation in colored scenes, but 0.36.1 remains a robust and high-performing version of the core Marty McFly RTGI technology.

However, this power comes with responsibility. Because RTGI is screen-space, it suffers from . If you turn the camera quickly, information at the edge of the screen disappears. For a split second, the "bounced light" might vanish until the new pixels are processed. Version 0361 handles this smoothing better than most, but it requires the user to understand that this is a post-process effect, not native engine integration.

While true multi-bounce ray tracing is too heavy for real-time post-processing, RTGI 0.36.1 uses clever mathematical approximations to simulate the soft, ambient scattering of secondary light.
Navigate to your game’s installation directory where the executable resides. Open the reshade-shaders folder. Place the qquint_rtgi.fx file inside the Shaders folder. (Z-buffer), which is the critical component required for
RTGI does not have access to the game's actual geometric data or scene graph. It only sees a 2D image and a Z-Buffer (depth map).
Check the box for your game's current resolution/depth format.
ReShade RTGI 0.36.1 is a specific older version of the Ray Traced Global Illumination
Controls how far a light ray travels before stopping. High values create sweeping shadows but can cause light leaking. Low values restrict the effect to tight corners. Ray Amount (Sample Count) Recommended Value: 3 (Medium) or 4 (High) This version, specifically, hit the sweet spot of
Light takes on the color of the surfaces it hits and bounces onto neighboring objects.
Always keep this checked. It relies on data from past frames to clean up the image, meaning you need fewer raw rays to get a clean look. Best Genres for ReShade RTGI
RTGI uses to simulate how light bounces off surfaces in a game world. Version 0.36.1 was part of the early "Beta" cycle, prior to the major overhauls seen in the 0.5x and 0.7x versions.
Find and download the ReShade_GI_Beta_0.36.1 files. You're looking for folders named "Shaders" and "Textures".
