Rtgi 01702 Fixed Jun 2026

The RTGI shader works by utilizing . It analyzes the depth data of the current frame to simulate:

: Ensure your "Launchpad" or depth-prepass shader is at the top of the load order to provide accurate depth data. Enable Motion Vectors

Dictates fine-detail secondary light scattering across complex geometry.

Global illumination (GI) simulates how light bounces between surfaces, producing soft shadows, color bleeding, and ambient occlusion. For decades, real-time applications relied on static or pre-baked solutions (e.g., lightmaps, probe volumes). The emergence of hardware-accelerated ray tracing (e.g., NVIDIA RTX, DirectX Raytracing) enabled dynamic RTGI, but at high computational cost.

This article explores what RTGI is, how it works, and why numbers like “01702” might be attached to it, offering a comprehensive guide for gamers looking to push their visual experience to the next level.
