Rtgi 0.17.0.2 Release Verified Info
The updated SDK improves compatibility with the latest HLSL and DXC (DirectX Shader Compiler) versions. Shader compilation times have been reduced, and edge-case compiler warnings that previously disrupted automation pipelines have been ironed out. Architecture: How It Works Under the Hood
Ray tracing is inherently demanding. Marty McFly improved the shader code to allow for a better balance between visual quality and GPU load, making it more feasible to run at higher resolutions without severe frame drops.
Install a compatible version of ReShade (often version 4.9.1 or higher was used for this build).
(often called ReSTIR GI or Pascal Gilcher’s GI ) remains the most advanced screen-space global illumination shader for ReShade. Version 0.17.0.2 is a minor but impactful patch following the major 0.17 update.

One of RTGI's most significant achievements is its . By operating solely on depth data, it is fully compatible with non-RTX video cards and has no inherent hardware feature requirements. This democratises ray tracing, allowing millions of gamers with older or non-RTX GPUs to experience the visual benefits of ray-traced lighting.
Improved temporal stability in high-motion scenes – less trailing behind moving objects/characters.
Installing RTGI 0.17.0.2 requires with depth buffer access enabled. The shader comes as a .fxh and .fx file. Add it to your ReShade Shaders/Shaders folder.
More recently, Gilcher has been working on a new sampling algorithm that, according to him, significantly outperforms (ReSTIR GI is a stochastic sampling algorithm that aims to achieve high-quality ray tracing with a limited sample budget). These advancements continue to push RTGI to the forefront of real-time ray tracing, even as GPU technology evolves. The updated SDK improves compatibility with the latest

Since 2020, the shader has evolved into the iMMERSE Pro suite, featuring more advanced algorithms like ReSTIR and improved denoising.
Today, when you browse through modding sites like Nexus Mods, you will frequently encounter references to the "RTGI 0.17.0.2 release." For many preset creators, it remains the gold standard for compatibility and stability. As one mod author notes, while the latest versions of RTGI (now part of the "iMMERSE Pro" suite) are significantly more advanced, presets built for version 0.17.0.2 are still celebrated for their consistent results. Marty McFly improved the shader code to allow
This dictates how far light can bounce.
The release of marked a pivotal moment in the shader's evolution. Arriving in late 2020, it represented a major leap forward in performance and visual fidelity. This update wasn't just another incremental fix; it was a carefully engineered overhaul that made ray-traced global illumination more accessible and effective than ever before.
Upgrade Guidance
The 0.17.0.2 update focused on three core areas: sampling efficiency, performance optimisation, and visual refinement.
