Enhanced stability across a wider variety of hardware, making it a safe "upgrade back" point for those who had reverted to legacy builds for reliability. Key Performance Benefits
: While the RTGI shader itself is often behind a paywall, the underlying math for shaders like this is frequently documented in white papers on Spatio-temporal Denoising Screen Space Ray Tracing available on platforms like ACM Digital Library NVIDIA Developer Are you trying to troubleshoot a specific rendering error in a game, or are you looking for the installation files themselves?
: High-frequency reflections scale back during intensive fast-paced scenes to save frames.

It works best with games that have a clear depth buffer, such as DirectX 9, 10, 11, and 12, or Vulkan titles. rtgi 01702 release fixed
Version 0.17.0.2 targeted game-breaking interaction flaws between the custom ray tracer and the ReShade depth buffer wrapper.
The 0.17.0.2 build introduced features that changed how screen-space data is calculated without hardware-bound RTX cores:
Improvements to how the shader interacts with a game's depth buffer, reducing flickering and incorrect shadow placement.
The many of the hurdles holding back early adopters of ray-traced ReShade. By addressing temporal stability and color accuracy, it enabled a superior visual experience. Even as technology progresses, the 0.17.02 update remains a testament to the rapid improvement of software-based ray tracing. Enhanced stability across a wider variety of hardware,
Within the ReShade menu, ensure the depth buffer is active (check the "DisplayDepth" shader to confirm it’s working).

Certain scenes, particularly those with dynamic weather or heavy skyboxes, caused the global illumination calculations to crash or cause severe screen flickering.

RTGI is a premium shader. The latest official builds and support are available through the creator's Marty's Mods Patreon or the PGHub Discord server.
If you experienced ghosting, fireflies, or crashes with 0.17.00/01, this update is essential. For users on 0.16.x, the jump to 0.17.02 brings the full ReGIR lighting benefits without the initial branch's growing pains.
Another critical issue resolved in this update was "light leaking," where light from a source would incorrectly illuminate areas behind solid objects, such as walls. The root cause was a disconnect between where the shader efficiently found intersections (for ambient occlusion) and where it accurately pinpointed them (for bounce light), leading to inaccurate lighting. The 0.17.0.2 release implemented a quick and effective fix for this issue, ensuring that shadows and light behavior were more physically accurate and eliminating the distracting glow-through-walls effect that can break immersion. Pascal Gilcher noted that he was already investigating even better methods for future releases, but this fix solved the problem for good in the immediate term.
