The primary focus of this release was correcting stability issues introduced during recent optimization passes. According to the release notes, the update specifically addresses the following:
However, pushing the boundaries of screen-space ray tracing often comes with trade-offs. Previous versions occasionally struggled with VRAM allocation or conflicts with ReShade’s depth buffer handling. The 0.17.02 release serves as a "quality of life" patch, ensuring that the graphical leaps taken in the 0.17 update remain stable across a wider variety of hardware configurations.
RTGI 0.17.0.2 (Ray Traced Global Illumination) beta was a significant update released by Pascal Gilcher

The RTGI 01702 release incorporates several technical advancements, including:
| Test case | 0.1701 result | 0.1702 result | |------------------------|---------------------|---------------------| | Outdoor day + shadows | Crash on load | Stable, correct | | Indoor multiple lights | Flickering indirect | Smooth indirect | | Temporal + motion | Ghosting visible | Ghosting removed |
Before diving into what’s new, it’s important to understand what RTGI is and what it does. The term "RTGI" stands for Ray-Traced Global Illumination , and at its core, it’s a method for generating incredibly realistic lighting in a 3D scene. Standard video game lighting often relies on "pre-baked" light maps and shortcuts. In contrast, real-time ray tracing simulates the physical behavior of light rays, bouncing them around a scene to produce more lifelike shadows, reflections, and ambient light. The primary focus of this release was correcting
