A calculation error in the surface normal detection caused light to bounce off objects at incorrect, pixelated angles.
The update targets long-standing screen-space global illumination glitches across DirectX 11 and DirectX 12 titles. Implementing this fix stabilizes lighting bounces, mitigates temporal flickering, and ensures seamless compatibility with the latest ReShade frameworks. Key Issues Resolved in 1.17.0.2
A milky, gray overlay that reduces contrast and destroys blacks. Performance drops: Higher-than-normal GPU usage. Shimmering/Noise: Unstable lighting behavior.
: If RTGI refers to a game engine feature like Real-Time Global Illumination, then "RTGI 01702 Release Fix" could be a patch to fix issues related to lighting in a game.

Optimizations to reduce the heavy FPS hit that ray tracing typically causes. Common Troubleshooting for RTGI
The 0.17.0.2 maintenance cycle isolates specific hardware conflicts and software engine interactions that previously caused screen-space ray tracing paths to collapse.
Resolving issues where the "flipping" or "inverting" of the depth buffer prevented the ray tracing effect from correctly detecting game geometry. Performance Optimization:
ReShade deliberately disables the depth buffer if it detects significant network traffic to stop players from exploiting competitive advantages. If you are playing an online or multiplayer game, RTGI will not function reliably unless you utilize a custom, modified build of ReShade that bypasses network blocking (only advised for offline private servers or single-player modes). A calculation error in the surface normal detection
RTGI 0.17.0.2 remains a foundational version for post-processing ray tracing. While it requires precise folder structure and depth buffer access, it provides a high-fidelity lighting solution for legacy and modern titles lacking native RTX support.
Always enable the option if your frame rate drops below your monitor’s refresh rate. Because RTGI applies a heavy blur and denoiser over the light passes, rendering the ray tracing at half resolution is rarely noticeable during active gameplay, but it can rescue 15 to 20 frames per second. Troubleshooting Ongoing Issues
The 01702 error often triggers because ReShade cannot locate the companion files required to build the RTGI effect.
