If you are new to the scene, RTGI is a ReShade filter that approximates the look of hardware-accelerated ray tracing on virtually any game. Unlike traditional screen-space reflections (SSR) or ambient occlusion (SSAO), RTGI calculates light bounces from the screen buffer, allowing for:

RTGI 0.17.0.2 refers to a specific, historical beta release of the Ray Traced Global Illumination (RTGI) shader created by Pascal Gilcher, widely known in the modding community as "Marty McFly". This shader is a post-processing tool injected into video games via ReShade to simulate advanced lighting effects like light bouncing and ambient occlusion without requiring native hardware-based ray tracing. 1. Overview of RTGI 0.17.0.2
Released on October 30, 2020, version 0.17.0.2 was a "Beta" milestone in the shader's development.
Purpose: It calculates how light fills a scene and bounces off surfaces to illuminate areas that standard game engines might leave unnaturally dark.
Compatibility: Unlike official RTX implementations, this shader operates on "Screen Space" data, meaning it can run on non-RTX graphics cards as long as the user can access the game's depth buffer.
Key Features (0.17.x Era): This version focused on stabilizing the temporal (time-based) aspects of the shader to reduce the "flickering" commonly seen in earlier releases. 2. Download and Distribution
The RTGI shader is not an open-source or free-to-distribute public file. Its official distribution is handled through a subscription model. Pascal Gilcher — Graphics Mods for Video Games - Patreon rtgi 0.17.0.2 download
If you have more details about where RTGI 0.17.0.2 is supposed to come from (e.g., a game, a specific 3D rendering software), I could offer more targeted advice.
The RTGI 0.17.0.2 (Ray Traced Global Illumination) shader is a graphics modification tool for ReShade, developed by Pascal Gilcher (also known as Marty McFly). This specific version was released in October 2020 as part of a beta testing phase. Download and Access
Official access to RTGI is strictly managed through a subscription model to support the developer's work.
Primary Source: The only official way to download RTGI 0.17.0.2 is through Pascal Gilcher's Patreon .
Cost: You must be a member of the $5 tier (Beta tier) or higher to unlock the download link.
Package: The download typically comes as a .zip file (e.g., ReShade GI Beta 0.17.0.2.zip) containing shader and texture folders. Installation Guide
To use RTGI, you must have ReShade already installed for your specific game. If you are new to the scene, RTGI
Install ReShade: Visit the official ReShade site to download and install the latest version for your game (e.g., GTA 5, Skyrim, or Horizon Zero Dawn).
Locate Shader Folder: Go to your game's installation directory and find the reshade-shaders folder.
Deploy Files: Extract the Shaders and Textures folders from the RTGI zip file and move them into the reshade-shaders directory. Replace files if prompted. Activate In-Game:
Press the Home key (or your designated ReShade hotkey) to open the menu. Search for "RTGI" and check the box to enable it. Community Status and Reception
Early Access Model: The shader has been noted for its "endless alpha" state, which some users on Reddit have criticized as a way to maintain monthly Patreon revenue.
Performance: RTGI 0.17.0.2 has known incompatibilities with ReShade’s "performance mode," which can cause breaking bugs if both are active.
Comparison: While newer versions exist, 0.17.0.2 remains a significant milestone in the beta's history for adding depth-based lighting and shadows to games that don't natively support ray tracing. How install RTGI/ReShade (2021) GTA 5 MODS RTGI 0
RTGI (often called Pascal Gli Shaders) is a popular screen-space ray tracing global illumination shader for ReShade. It adds realistic light bouncing, ambient occlusion, and indirect lighting to older or non-ray-traced games.
Version 0.17.0.2 is a well-known stable release from the pre‑5.0 era, before the developer (Pascal Gilcher) moved to a paid early access model for newer versions.
Because the newer RTGI versions moved to a paid tier via Patreon (archived access), many free users specifically seek out 0.17.0.2 as the last fully stable, widely distributed free version.
How does this 2-year-old shader compare to native RTX?
| Feature | RTGI 0.17.0.2 | Native RTX (Cyberpunk) | | :--- | :--- | :--- | | Performance Hit | Medium (10-20 FPS loss) | Severe (30-50 FPS loss) | | Per-Pixel Accuracy | No (Screen-space noise) | Yes (Hardware accelerated) | | Reflections | No | Yes | | Shadows | No (Uses in-game shadows) | Yes | | Cost | Free | Expensive (RTX GPU required) |
Verdict: RTGI 0.17.0.2 is a phenomenal upgrade for GTX 1000/1600 series cards that cannot run official ray tracing. For RTX users, you can run this alongside DLSS for a unique hybrid look.
