The RTGI 0.17.0.2 release is a critical update for Marty McFly’s (Pascal Gilcher) Ray Traced Global Illumination shader, a popular ReShade add-on that brings realistic path-traced lighting to nearly any 3D game. This version was specifically released to address compatibility issues and "broken" lighting effects in certain titles, such as Alien: Isolation and older DX9/DX11 games. What is RTGI 0.17.0.2?
RTGI (Ray Traced Global Illumination) is a shader that calculates how light "bounces" off surfaces in real-time, adding depth, shadows, and color bleeding that typical game engines miss. Version 0.17.0.2 was a "fix" release designed to improve the shader's stability on newer ReShade builds and fix specific edge-case artifacts. Key Fixes in this Release
While primarily a maintenance update, the 0.17.0.2 release addressed several community-reported bugs:
Depth Buffer Alignment: Fixed issues where the ray tracing would "separate" or ghost at the edges of the screen, particularly when using ReShade 4.9.1.
Object Vanishing: Addressed a bug where objects would disappear or flicker when viewed directly through the shader’s light path.
Performance Stability: Refined the shader’s interaction with the ReShade API to reduce crashes in 32-bit and 64-bit environments. How to Install and Fix RTGI 0.17.0.2
To get the 0.17.0.2 "fix" working correctly, follow these steps:
Download Files: You must be a subscriber to Pascal Gilcher’s Patreon to access the official ReShade GI Beta 0.17.0.2.zip.
Update ReShade: Ensure you are using a compatible version of ReShade. While 4.9.1 was common at the time of release, many users now recommend ReShade with Full Add-on Support to avoid depth buffer glitches.
File Placement: Drag the Shaders and Textures folders from the RTGI zip into your game’s reshade-shaders directory. Configure Depth Buffer: rtgi 01702 release fix
In the ReShade menu, enable DisplayDepth.fx to verify your depth buffer is visible.
If the screen is black or "split," disable in-game Anti-Aliasing (MSAA/TXAA) and Post-Processing, as these often block the data RTGI needs.
Check RESHADE_DEPTH_INPUT_IS_REVERSED in the global preprocessor definitions to ensure shadows cast in the right direction. Common Issues & Solutions
Here’s a blog post draft tailored for the RTGI (Realtime Global Illumination) shader, specifically for a fix release labeled 01702. Adjust the project name or context (e.g., a specific game mod, Reshade shader, or rendering tool) as needed.

We’re pleased to announce the immediate availability of RTGI update 01702. This is a fix-focused release aimed at resolving several issues reported by the community since the previous build.

shader created by Pascal Gilcher (also known as Marty McFly). What is RTGI 0.17.0.2? Released in October 2020
, version 0.17.0.2 was a beta update for the RTGI shader, which adds high-end ray-traced lighting effects to older or non-RT games via the ReShade injector. This specific version was part of a series of early refinements designed to optimize how light interacts with game environments. Key Fixes and Features in this Release While the full changelog is behind the Marty's Mods Patreon
, common "fixes" associated with this era of RTGI development included: Depth Buffer Stability:
Improvements to how the shader accesses a game's "depth buffer" to accurately place light and shadows. Noise Reduction:
Updates to the "denoiser" to prevent flickering or graininess in the lighting. Performance Tweak:
Optimizations to reduce the heavy FPS hit that ray tracing typically causes. Common Troubleshooting for RTGI
If you are looking for a "fix" because the shader isn't working for you, users often solve issues by: Checking Depth Buffer Settings: In the ReShade menu, ensure RESHADE_DEPTH_INPUT_IS_REVERSED is set correctly (toggle between 0 and 1). Disabling In-Game Anti-Aliasing:
Many games use TAA (Temporal Anti-Aliasing) or MSAA that can block the shader from "seeing" the depth of the scene. Update to Latest Version: Title: RTGI v01702 Release: Critical Fixes & Stability

The RTGI release fix checks process affinity; any process older than the release timestamp will cause a conflict.
The term "release fix" suggests that there's a specific problem or set of problems being addressed in a software or game release. This could be a maintenance release, a patch, or an update aimed at resolving issues found in the initial release or previous versions.
The RTGI engine creates a .release_lock file in the deployment directory during promotion. If a previous release was interrupted (power failure, Ctrl+C, network timeout), this file persists. The new release sees the lock and throws 01702.
Do not delete the entire cache if you need rollback ability. Instead, clear only the validation cache:
rtgi-cli cache clear --type validation
If the error continues after the steps above, perform a full release directory purge (excluding configuration files):
mv /opt/rtgi/releases/current /opt/rtgi/releases/current.corruptedrtgi-cli init --fresh --config /etc/rtgi/config.ymlThis approach forces a clean slate but loses the ability to roll back to the previous release.
