: Download the corresponding framework version from ReShade's official site and run the installer.

If the shader does nothing, your depth buffer is likely not set up correctly. Check the DisplayDepth shader to see if you have a clear black-and-white view of the world.

Disable in-game Anti-Aliasing (MSAA) and Ambient Occlusion (SSAO), as these often conflict with ReShade's depth access. rtgi 0.17.0.2

In the rapidly evolving world of PC gaming graphics, few community-driven tools have made as significant an impact as . Specifically, the RTGI 0.17.0.2 beta release, released in late 2020 by developer Pascal Gilcher (Marty McFly), was a landmark version that significantly enhanced visual fidelity and temporal stability in thousands of titles.

Reduce performance cost on rough surfaces while maintaining quality on smooth/reflective ones.

represents a milestone update for the Ray Traced Global Illumination (RTGI) shader developed by graphics modder Pascal Gilcher (commonly known as Marty McFly). Released via Pascal Gilcher's Patreon , this specific beta version significantly improved how classic and modern video games process screen-space lighting. It bridges the gap between traditional rasterized graphics and hardware-accelerated path tracing without requiring a native RTX graphics card. Reduce performance cost on rough surfaces while maintaining

The following sections break down the mechanics, core features, installation steps, and optimization strategies for the RTGI 0.17.0.2 shader. What is RTGI 0.17.0.2?

Version 0.16.x was considered the gold standard for years. However, changes the game.

Drastically reduces the "noise" or graininess typical of real-time ray tracing, delivering a butter-smooth image. while games with solid

RTGI cannot see the sides or backs of objects that are not visible to the camera—it must estimate how far objects extend beyond their visible surfaces. The parameter controls this estimation. The default value is 0.250 , which works well for many games. However, optimal values vary significantly: games with thin objects (like foliage) typically need lower values, while games with solid, thick geometry may benefit from higher numbers.

RTGI 0.17.0.2 is now available for download on the official website, with a free trial and demo version offered for developers to test the technology. A commercial license is required for production use.
