Below is a draft of the key features and technical improvements included in this specific version: RTGI 0.17.0.2 Feature Set Integrated Spatial Denoising
Since 2020, the shader has evolved into the iMMERSE Pro suite, featuring more advanced algorithms like ReSTIR and improved denoising.
, bringing another layer of visual fidelity to your favorite titles. This update continues to refine how light, shadows, and color bounce interact with 3D environments, making "flat" game worlds feel remarkably physical and alive. What’s New in 0.17.0.2? rtgi 0.17.0.2 release
The RTGI project has been actively developed over the past few years, with a team of dedicated researchers and engineers working tirelessly to push the boundaries of real-time lighting. The project has seen several significant releases, each bringing incremental improvements and new features to the table. The latest release, RTGI 0.17.0.2, marks a major milestone in this journey, offering a plethora of enhancements that solidify its position as a leading solution for real-time global illumination.

For the uninitiated, RTGI is a post-processing shader used via ReShade. It injects path-traced global illumination, ambient occlusion, and physical light bounces into almost any 3D game. It essentially transforms aging titles and modern games alike, giving them the visual fidelity of native ray tracing without needing a native engine overhaul.
This version focuses on performance optimization and stability, ensuring that high-end lighting doesn't always require a high-end frame rate tax. Refined Lighting Accuracy What’s New in 0
Earlier versions often struggled with flickering in high-contrast areas; this release cycle introduced workarounds and patches to stabilize the lighting channel.
You can easily run the shader on "Ultra" or "Very High" settings at 1440p or 4K, experiencing a minor performance hit of roughly 10–15%.
The 0.17.0.2 release was a testament to RTGI's growing influence. By 2020, the shader's ability to deliver fully dynamic ray traced lighting was already being featured in news outlets and adopted by major industry players. Its integration was so seamless that NVIDIA had already incorporated the technology into its NVIDIA FreeStyle and Ansel driver modules for select games under the name “SSRTGI”.
