Rtgi 01702 Release Fix

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:

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

Traditional global illumination (GI) in older games is often baked or relies on low-fidelity screen-space ambient occlusion (SSAO). The development of the RTGI shader by Pascal Gilcher represents a paradigm shift, allowing real-time path-traced approximations in legacy DX9-DX12 titles 2. Methodology: Screen-Space Path Tracing

Unlike hardware-accelerated ray tracing (RTX/DirectX Raytracing), RTGI operates strictly on the information visible on the screen. It utilizes: Ray Marching:

Stepping through the depth buffer to detect geometry intersections. Denoising:

Filtering high-frequency noise inherent in low-sample-count ray tracing. Temporal Reprojection:

Reusing data from previous frames to stabilize the lighting solution.

The RTGI 0.17.0.2 update (released October 30, 2020) is a beta version of Pascal Gilcher's Ray Traced Global Illumination shader for ReShade. This specific version was widely adopted by modding communities for its balance of performance and visual quality in titles like Red Dead Redemption 2 and Skyrim. Core Fixes & Performance Tips

If you are experiencing issues with this version, the most common "fixes" involve configuring the depth buffer correctly, as RTGI requires accurate depth data to calculate lighting.

Depth Buffer Setup: Ensure "DisplayDepth" is active to troubleshoot. If the screen is gray or inverted, go to the "Edit global preprocessor definitions" and toggle RESHADE_DEPTH_INPUT_IS_REVERSED between 0 and 1.

Buffer Access: In the ReShade "Add-ons" tab, check "Copy depth buffer before clear operations" if the lighting effects are flickering or missing.

Resolution Matching: Verify that the depth buffer layer matches your game's current resolution. Uncheck "Generic Depth" and manually select the correct layer if necessary. The RTGI 0

In-Game Conflict: Disable temporal effects like TAA or MSAA within your game's settings, as these often block ReShade from accessing the depth buffer.

The RTGI 01702 release fix refers to a critical update for Ray Traced Global Illumination (RTGI), a specialized post-processing shader developed by Pascal Gilcher (also known as "Marty McFly"). This shader is used via ReShade to simulate advanced lighting effects like global illumination and ambient occlusion in games that do not natively support them.

The "01702" version (also referred to as v0.17.0.2) was primarily a hotfix designed to resolve stability and rendering issues introduced in the major v0.17 branch. Key Improvements in the 0.17.0.2 Fix

Buffer Depth Resolution: Fixed issues where the shader would fail to correctly interpret the depth buffer in certain DX11 and DX12 titles, which previously led to flickering or "ghosting" effects.

Performance Optimization: Refined the spatial denoising algorithms to reduce the GPU overhead. This allows for smoother frame rates when the "Ultra" quality preset is selected.

Material Interaction: Improved how light bounces off transparent or semi-opaque surfaces, preventing the "glowing" artifact sometimes seen on water or glass textures.

UI/Config Fixes: Addressed a bug where specific user-saved presets would revert to default settings upon restarting the game. How to Apply the Fix

Download: Access the updated .fx and .fxh files through the official Marty's Mods Patreon or authorized distributor.

Installation: Replace the existing RTGI.fx file in your game's reshade-shaders/Shaders folder.

Compiler Refresh: Inside the game, open the ReShade menu (usually the Home key) and click "Reload" at the bottom to ensure the 01702 logic is active.

Phase 3: Nuclear Option (If error persists)

If the error continues after the steps above, perform a full release directory purge (excluding configuration files):

1. Stop all RTGI-related services.
2. Rename the existing release folder:
   mv /opt/rtgi/releases/current /opt/rtgi/releases/current.corrupted
3. Re-initialize the RTGI runtime:
   rtgi-cli init --fresh --config /etc/rtgi/config.yml
4. Redeploy the release from the CI/CD artifact store.

This approach forces a clean slate but loses the ability to roll back to the previous release.

5. Permission Degradation on Temp Directories

RTGI writes temporary validation files to %TEMP%\RTGI\session_id. If a security policy changed (e.g., Group Policy Objects removing write access), the release cannot finalize.

Known Remaining Issues

• HDR output on OpenGL remains experimental (targeting next release).
• Performance regression in heavy foliage scenes – we’re investigating.

6. Version Skew in Dependent Modules

RTGI 01702 often appears when a core module (e.g., rtgi_core.so or RTGI.Engine.dll) is at version X.Y.Z but a dependent plugin expects X.Y.Z+1.

2. The Star Feature: The "Filter" Slider

This was introduced in the 0.27 branch and polished in the fix. It is a game-changer for image quality.

• Before (Legacy versions): RTGI often suffered from "splotchy" noise or jagged shimmering, especially on distant surfaces. You had to crank up the "Sampling Quality," which tanked your FPS.
• With the Fix: The "Filter" slider applies a smart spatial filter that smooths out the noise without blurring the detailed ray-trounced shadows.
• Why it’s helpful: You can now run the shader at lower sampling rates (saving FPS) and use the Filter to clean up the image. It makes the "High" setting look like "Ultra" at a fraction of the cost.

3. Regular Cache Rotation

Configure a cron job or scheduled task to clear the RTGI validation cache weekly: "RTGI" could stand for a project name, a

0 2 * * 0 /usr/local/bin/rtgi-cli cache clear --type validation --older-than 7d
