Allows you to feed the game's actual sky color into the ambient lighting calculations. Setting this to "Dynamic" ensures that morning light looks warm and night light looks cool. 3. The Performance Checklist
RTGI stands for Real-Time Global Illumination, a technology that simulates the way light interacts with the environment in a scene. In traditional rasterization-based rendering, lighting is often approximated using techniques like baked lighting maps or screen-space ambient occlusion (SSAO). However, these methods have limitations, particularly when it comes to accurately capturing complex lighting scenarios.
Released in 2021, RTGI 0.3.3 is a proprietary ReShade shader shader developed by Pascal Gilcher (Marty McFly). It is designed to emulate ray tracing in real-time by analyzing the screen's depth buffer and color data, essentially performing a "screen-space path tracing" operation.
Drastically improved contact shadows in corners and crevices. 🚀 What Made Version 0.33 Special?
To achieve the best balance between visual fidelity and framerate, tweak these specific parameters inside the ReShade menu: Ray Amount and Steps

RTGI cannot function without a perfectly configured depth buffer. Open the ReShade overlay (usually the Home key). Navigate to the tab.
Works best on DirectX 11, DirectX 12, or Vulkan titles. 🛠️ Installation Steps
