Running RTGI comes at a high computational cost. Fine-tuning the shader options in the ReShade overlay ( Home key) balances framerates and visual fidelity. Setting Name Recommended Value Performance Impact Visual Result Determines the crispness of light paths and soft shadows. Step Amount Limits how far a ray can check for geometry intersections. Ray Length Controls the distance light bleeds across flat planes. Z-Thickness Prevents light leaking behind thin background objects. ⚠️ Troubleshooting Common Depth Buffer Issues

: When a ray hits an illuminated surface, it samples its color and reflects it onto adjacent textures.

In games with moving suns (like The Witcher 3 or Skyrim ), shadows shift smoothly, stretching and softening naturally as dusk approaches. Optimal Settings Guide for RTGI 0.17.0.2

Expect a 20% to 30% drop in FPS at 1080p/1440p using optimized settings.

For modders and visual purists, the quest for perfect lighting is never-ending. While modern "RTX-ready" games come with built-in ray tracing, older classics are often left in the dark—literally. Enter , the specialized shader for ReShade that brings global illumination and ambient occlusion to titles that were never designed for it. What makes RTGI 0.17.0.2 special?

RTGI is a software solution that allows developers to integrate high-quality global illumination into their applications in real-time. Global illumination, a crucial aspect of computer graphics, simulates the way light interacts with various objects and materials in a scene, creating a more immersive and realistic experience for users. RTGI achieves this through advanced algorithms and techniques, making it possible to render complex lighting scenarios quickly and efficiently.

A common question: "Why use RTGI if I own an RTX card?"

Help you (like the depth buffer not working).

She turned the avatar toward the fireplace. In reality, the fire had been the death of the house. In the simulation, she had never dared to turn it on. The emissive source—the flames—would always crash the shader. The logs would read: Unstable radiance cache . But version 0.17.0.2 had a new line: Improved stability near emissive sources.

If your character stands next to a neon blue sign, their clothes and the surrounding concrete will realistically catch a blue tint.
