Reshade Rtgi 0361 Extra Quality May 2026

The ReShade RTGI 0.36.1 shader, developed by Pascal Gilcher (widely known as Marty McFly), represents a significant milestone in post-processing technology, bridging the gap between legacy rendering and modern, high-fidelity lighting. The Mechanics of Ray-Traced Global Illumination (RTGI)

At its core, RTGI (Ray Traced Global Illumination) is a screen-space effect that simulates how light bounces off surfaces to illuminate others. Unlike standard lighting, which often leaves corners and non-directly lit areas looking flat, RTGI calculates:

Secondary Bounces: Light hitting a red floor will subtly "bleed" a red hue onto the surrounding white walls.

Ambient Occlusion: Accurate, soft shadows are generated in crevices and where objects meet, grounding them in the world.

Diffuse Global Illumination: It creates a natural gradient of light that flows through scenes, particularly beneficial for older titles with static or pre-baked lighting. The "Extra Quality" Benchmark

In version 0.36.1, the "Extra Quality" setting maximizes the precision of these calculations. While standard settings might use fewer rays to save performance, "Extra Quality" increases the ray count and sampling density, leading to:

Reduced Flickering: Higher sample counts stabilize the light, reducing the "wobbly" light artifacts common in lower-tier screen-space ray tracing.

Fine Detail Shadowing: It allows for microscopic contact shadows on textures, making materials look "grittier" and more "lived-in". reshade rtgi 0361 extra quality

Extended Bounce Distance: Light can travel further from its source before fading, creating more realistic interior lighting in cavernous spaces.

RTGI (Ray-Traced Global Illumination) by Pascal Gilcher (Marty McFly) is a highly sought-after shader for ReShade that simulates real-time ray tracing in games that don't natively support it. The version 0.36.1 represents a refined iteration of this shader, offering "Extra Quality" settings to enhance path-traced lighting, shadows, and ambient occlusion. Core Features of RTGI 0.36.1

Path-Traced Lighting: Simulates how light bounces off surfaces, creating realistic color bleeding (e.g., a red wall casting a red tint on the floor).

Advanced Ambient Occlusion: Adds deep, realistic shadows in corners and crevices where light is naturally occluded.

Extra Quality Settings: Includes higher sample counts and improved denoising filters to reduce the "flickering" or noise often associated with screen-space ray tracing.

Motion Vectors Support: Modern versions (0.33+) use motion vectors to better track lighting between frames, significantly reducing ghosting during movement. Optimal "Extra Quality" Configuration The ReShade RTGI 0

To achieve the best visual results with version 0.36.1, focus on these specific parameters within the ReShade menu:

Ray Length & Steps: Increasing these values allows light to travel further and interact with more geometry, but it is the most performance-heavy adjustment.

Sample Count: For "Extra Quality," set this to High or Ultra. This determines how many "rays" are cast per pixel; higher values result in smoother shadows and less noise.

Denoising Filter: Ensure the denoiser is active. This smooths out the raw, grainy ray-traced output into a cohesive image.

Z-Thickness: Adjust this to prevent light from "leaking" through thin walls or objects, a common artifact in screen-space effects. Setup Requirements

Access: RTGI is typically available through Marty McFly's Patreon.

Depth Buffer: You must have a working depth buffer for RTGI to function. Disable in-game Anti-Aliasing (MSAA) and ensure "Copy depth buffer before clear operations" is checked in the ReShade "Generic Depth" tab. Installation: Download the shader files (qUINT_rtgi.fx and textures). Ambient Occlusion : Accurate, soft shadows are generated

Place them in your game's reshade-shaders/Shaders and Textures folders. Enable qUINT_rtgi at the top of your shader list. Performance Impact

Using "Extra Quality" settings on RTGI 0.36.1 is demanding. It is recommended for users with at least an RTX 3060 / RX 6700 XT or higher to maintain a stable 60 FPS, especially at 1440p or 4K resolutions.

To utilize the Extra Quality moniker, you cannot leave the settings on default. Here is the optimal performance-to-quality preset.

Before diving into the specifics of version 0361, let’s establish the basics. ReShade is a generic post-processing injector for games. It allows developers and artists to create custom shaders (FX files) that alter the game’s render output.

RTGI, or "Ray Traced Global Illumination," is a shader that approximates how light bounces off surfaces. Unlike simple screen-space ambient occlusion (SSAO), which only darkens corners, RTGI analyzes the depth buffer and color buffer to cast light and shadow from nearby surfaces.

The result? Corners are no longer just dark; they are filled with naturally colored bounce light.
