Reshade Rtgi 0.36.1 May 2026

| Setting | What it does | Recommended start | |--------|--------------|------------------| | Quality | Ray sample count (Low = noisy, High = slower) | Medium or High | | Radius | How far light bounces (small = local, large = room-scale) | 0.4 – 0.8 | | Bounce Intensity | Brightness of indirect light | 0.6 – 1.2 | | Bounce Saturation | Color bleed strength (red brick reflecting red onto wall) | 0.3 – 0.6 | | Ambient Occlusion Mix | Blends SSAO-style darkening with GI | 0.4 – 0.7 | | Temporal Amount | Reduces flicker using previous frames | 0.65 – 0.85 (higher = less noise, more ghosting) |

Avoid overdoing Bounce Intensity above 1.5 – it crushes shadows and washes out contrast.

RTGI (Ray Traced Global Illumination) is a ReShade shader that approximates light bounces in real time. Unlike screen-space ambient occlusion (SSAO), which only darkens crevices, RTGI simulates color bleeding and indirect lighting.

Version 0.36.1 is special because:

Important limitations (free vs. paid):

Nevertheless, for 80% of games, 0.36.1 delivers a stunning, noticeable upgrade in lighting depth.

If you’ve ever wanted ray-traced global illumination in older games like Skyrim, GTA V, Fallout 4, or Mass Effect, ReShade RTGI 0.36.1 is the most accessible entry point. This version represents the last free, open-source release of the shader before it evolved into the paid "RTGI (Full)" available on Patreon. Reshade Rtgi 0.36.1

Below is everything you need to know: what it does, how to install it, and how to tune it for actual visual gains (not just a crushed black mess).

While RTGI 0.36.1 is impressive, it is bound by the constraints of Screen-Space effects:

Version 0.36.1 refined the balance between visual fidelity and performance. Key configuration parameters in this version include: | Setting | What it does | Recommended

In the ever-evolving world of PC gaming graphics, few mods have generated as much excitement as Pascal "Marty McFly" Gilcher’s Ray Tracing Global Illumination (RTGI) shader. While hardware-accelerated ray tracing (RTX) remains exclusive to newer graphics cards, RTGI has democratized cinematic lighting for thousands of older titles. Among its many iterations, one version stands out as a landmark release: ReShade RTGI 0.36.1.

This article dives deep into what makes version 0.36.1 special, how it differs from standard screen-space effects, the technical requirements, installation steps, and the best settings to transform your games.
