Assuming you have a copy, here is how to inject it into your game (using The Witcher 3 or Cyberpunk 2077 pre-Path Tracing as an example).

In the rapidly evolving world of PC gaming graphics, Ray Tracing Global Illumination (RTGI) has become a sought-after technology. Specifically, user-modified shaders like —often associated with Marty McFly’s Reshade shader—offer incredible visual enhancements to older or non-ray-traced games.

RTGI 0.17.0.2 is an early beta version of the popular screen-space ray tracing shader. Unlike native Ray Tracing, which requires specific hardware like NVIDIA's RTX cores, RTGI works through , a post-processing injector. It calculates lighting and shadows based on the game's depth buffer . rtgi 01702 download verified
Full RTGI is part of the iMMERSE Pro suite, which is Marty’s high-end effect collection. ( www.patreon.com/mcflypg ). This is the only official and verified source for the full RTGI shader. Once you become a patron, you will get access to a download for the iMMERSE Pro suite. Inside this package, you will find the RTGI shader files, which are typically what you place in your game's reshade-shaders\Shaders folder.
Released around late 2020, this version was considered a significant, stable release during the early, rapid development phase of the project.
When prompted to select effect packages, ensure the standard and Quint packs are checked, then complete the installation. Phase 2: Deploying RTGI Shaders Extract your verified RTGI 0.17.0.2 zip archive. Inside, locate the Shaders and Textures folders.
This removes the complexity of manually downloading and verifying shader files. It ensures that specific presets like rtgi 01702 are applied only to hardware that can support them, preventing game crashes or unplayable frame rates. Assuming you have a copy, here is how
Setting up RTGI can require some fine-tuning for each game. Here are solutions to common problems:
because it uses depth-buffer data rather than dedicated ray-tracing cores. Compatibility: It is widely used for games like The Witcher 3 to give them a "next-gen" look. Installation Basics
: Websites claiming to offer a "free cracked download" of version 0.17.0.2 frequently package the zip archive with trojans or crypto-miners.
The only legitimate and verified source for the most up-to-date and reliable versions of RTGI shaders is through page. You are getting the actual code from Marty McFly/iMMERSE
If playing single-player games, ensure you check the box to install ReShade with full add-on support. This allows the software to read the game's depth map, which RTGI requires to calculate light paths.
Step 2: Download Free Community Alternatives (If Budget is an Issue)
Before we explain how to download a verified copy, let’s examine the risks of grabbing the first link from a search engine.
RTGI needs to access the game's depth buffer to work. After launching your game, open the ReShade overlay (default key: Home ), go to the "Add-ons" tab, and select the correct depth buffer until the "DisplayDepth" shader shows a half-color, half-greyscale image. Then, deselect the "DisplayDepth" shader and enable RTGI in the "Home" tab.
