RTGI is a paid shader available through Marty McFly's Patreon . While version 0.36.1 was a major milestone, later versions (such as 0.40 and beyond) have since been released, further improving reflection quality and integration.
| Feature | RTGI 0.36.1 | Newer versions (0.51+) | |---------|-------------|-------------------------| | | Extremely stable, well‑tested | May have early bugs after big changes | | Performance | Balanced, known behavior | Potentially faster or slower depending on algorithm changes | | Compatibility | Works with most games and older GPUs | Some new features may require driver or API updates | | Availability | Easier to find as the older stable version | Requires Patreon subscription at higher tiers | | Reflections | Good, but screen‑space only | Newer version adds HiZ Min‑Max Tracing for pixel‑perfect reflections |
: Because it operates on depth data rather than dedicated hardware cores, RTGI is compatible with non-RTX cards, though it remains "performance hungry" and should not be used on low-end systems.
Gilcher continues to develop RTGI while also working on more advanced path‑tracing add‑ons. However, RTGI remains his signature work, and version 0.36.1 is the result of years of refinement.
Ensure is enabled in the ReShade "DX11/12" tab if shadows appear flicker or transparent. Reshade Rtgi 0.36.1
While Gilcher has released later builds (0.51, 0.52, and a major “biggest update yet” in 2025), version 0.36.1 still holds value for many players.
represents a mature stage of this technology, focusing heavily on fixing previous limitations regarding color accuracy and flickering. Key Features of the 0.36.1 Era
RTGI 0.36.1 works with . That means:
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. RTGI is a paid shader available through Marty
To understand what makes RTGI effective, it helps to know what happens when you turn it on:
Expect a performance drop of 15% to 40% depending on your hardware and chosen settings. Conclusion
For the best results in 0.36.1, ensure your "MotionVectors.fx" shader is properly configured to allow the lighting to stick to moving objects. Installation Steps
For gamers with high-end hardware, ReShade RTGI 0.36.1 offers an opportunity to experience games with visual fidelity that rivals, if not surpasses, next-generation console graphics. Gilcher continues to develop RTGI while also working
Acquiring RTGI 0.36.1 is a straightforward process, though it is not free. Pascal Gilcher's work is funded directly by the community through his . The shader is currently available to supporters at the "Photon Mappers" tier , which costs $20 per month. This tier also provides access to the new path-traced volumetric fog and other experimental features.
This guide covers how version 0.36.1 works, its system requirements, installation steps, and optimization strategies. What is ReShade RTGI 0.36.1?
: Refinements to the sampling algorithm provide more realistic light bounces and better-defined contact shadows (ambient occlusion).
The update brings forth a more sophisticated algorithm for calculating global illumination. This results in more accurate lighting that closely mimics real-world conditions. Moreover, efforts have been made to minimize common artifacts associated with real-time GI solutions, such as flickering or incorrect lighting in certain scenarios.
