Understanding the RTGI 0.17.0.2 Release Fixed Version The RTGI 0.17.0.2 update is a specific version of the Ray Traced Global Illumination (RTGI) shader for ReShade, created by developer Pascal Gilcher (also known as Marty McFly). This specific release, originally launched on October 30, 2020, was a key milestone in the shader's development, addressing critical stability and performance issues found in earlier versions. What is RTGI?
RTGI is a post-processing shader that adds real-time, ray-traced lighting effects to almost any video game. By simulating how light bounces off surfaces, it introduces dynamic global illumination and ambient occlusion that can dramatically improve the realism of older titles or games lacking native ray tracing support. Key Features of the 0.17.0.2 "Fixed" Release
While the term "fixed" often refers to user-applied patches or official hotfixes, the 0.17.0.2 release itself was a stability-focused update following the initial 0.17 rollout. Key aspects of this era of RTGI include:
Depth Buffer Stability: Improvements to how the shader interacts with a game's depth buffer, reducing flickering and incorrect shadow placement. rtgi 01702 release fixed
Performance Optimization: Refinements to the shader code allowed for a better balance between lighting quality and frame rate.
Broad Compatibility: This version maintained support for a wide range of APIs, including DX9, DX11, DX12, OpenGL, and Vulkan. Evolution Since Version 0.17
It is important to note that as of 2026, version 0.17.0.2 is considered highly outdated. The shader has since evolved into the iMMERSE Pro: RTGI suite, which is adopted by NVIDIA for use in their GeForce Experience FreeStyle filters. marty's modshttps://www.martysmods.com Devlog July 2023 - MARTY'S MODS
Release Date: February 2024 (Legacy Update)
The latest iteration of the ReSTIR-based path tracing shader, RTGI v0.17.02, has been released as a targeted hotfix. While the v0.17 branch introduced significant improvements to ReGIR (ReSTIR with GIR) and temporal stability, version 0.17.02 focuses on correcting critical bugs that impacted visual quality and performance in specific game engines (notably Unity and ReShade-based pipelines).

RTGI 0.17.02 is a stability-first release. If you experienced ghosting, fireflies, or crashes with 0.17.00/01, this update is essential. For users on 0.16.x, the jump to 0.17.02 brings the full ReGIR lighting benefits without the initial branch's growing pains.

The release tagged as RTGI 0.17 (specifically the builds circulating as 0.17.02) resolved the critical "Crash on Toggle" bug that plagued the v0.16 user base. It established a new baseline for stability, making the shader viable for extended gameplay sessions without fear of instability. For users still on older versions, updating to the fixed v0.17 release is mandatory to ensure compatibility with modern GPU drivers and ReShade versions.
The primary focus of this release was correcting stability issues introduced during recent optimization passes. According to the release notes, the update specifically addresses the following: Note: RTGI is a Patreon-supported project

For users who may have reverted to older builds (such as 0.16) due to crashes, the 0.17.02 release is a strong invitation to upgrade back to the latest version. The performance overhead remains consistent with the 0.17 branch, offering better visual fidelity than 0.16 for roughly the same frame cost, provided the crashes have been resolved.
Users are reminded that RTGI remains a Patreon-supported project. As such, access to the 0.17.02 binary requires an active subscription to the developer's Patreon page.
