Rtgi 0.17.0.2 Release [work] Jun 2026

Installing 0.17.0.2 (concise steps)

Common troubleshooting

Ensure you are using the latest version of ReShade with full add-on support enabled, as depth buffer access is mandatory.

To appreciate what makes the 0.17.0.2 version a critical stepping stone, it helps to understand what the shader actually does. rtgi 0.17.0.2 release

: Return to the main shader list, check the box next to RTGI, and tweak the user interface sliders to match your game's art style. The Verdict: Is It Worth It?

Unlike modern implementations that rely on NVIDIA's dedicated RT cores, RTGI operates solely on depth and color data from the game's final rendered frame. This ingenious approach gives it a unique advantage: . By using innovative methods to accelerate ray marching and reconstructing meshes from depth input, it often outperforms hardware-accelerated ray tracing on certain meshes. Initially distributed through his Patreon as a paid beta, the RTGI 0.17.0.2 release quickly became a sought-after tool for enhancing lighting quality across hundreds of games, from The Witcher 3 to Cyberpunk 2077 .

Surfaces now interact realistically with ambient light based on their material properties. Matte surfaces diffuse light softly across a wide area, while glossy materials exhibit sharper, localized reflections. Infinite Bounces Simulation Installing 0

The solidifies Pascal Gilcher's shader as an indispensable tool for PC gaming enthusiasts. By shifting the focus toward stability, temporal cleanup, and clever caching algorithms, this update moves RTGI away from being a mere "screenshot tool" into a highly viable, real-time gameplay enhancement. Whether you are wandering the streets of an older Grand Theft Auto , exploring the wastes of Fallout 4 , or upgrading an indie title, 0.17.0.2 delivers breathtaking, next-generation atmosphere right to your screen.

Move the .fx and .fxh files from the RTGI package into your game's reshade-shaders/Shaders and Textures directories.

A screen-space shader is only as good as the depth data it reads. This iteration ironed out standard bugs where weapons or user interface (UI) elements would accidentally catch light rays or cast giant, unrealistic silhouettes across the skybox. 3. Infinite Bounce Approximations The Verdict: Is It Worth It

Let’s be honest: RTGI has looked good since version 0.12. The question is, how much better can screen-space ray marching get?

Older versions of RTGI struggled with dark corners, often creating a flat, pitch-black look where light died out too quickly. Version 0.17.0.2 introduces a more refined approximation of infinite light bounces. Light now accurately reflects off a surface, hits a second surface, and subtly illuminates a third. This completely eliminates the harsh, unnatural black gradients in indoor scenes. 2. Radical Temporal Accumulation Upgrades

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
