Controls the brightness of the bounced light. Keep this subtle (around 1.0 to 1.5 ) to prevent the scene from looking washed out.
Unlike native ray tracing solutions from Nvidia (RTX) or AMD (RX), RTGI 0.33 does not rely on hardware-level BVH (Bounding Volume Hierarchy) traversal. It executes entirely through standard compute shaders. This means you can run ray-traced global illumination on older graphics cards, including the Nvidia GTX 10-series or older AMD Radeon cards.

Ray tracing used to be reserved for high-end GPUs and modern titles. However, thanks to Pascal Gilcher’s , players have been able to inject path-traced lighting into almost any game with a depth buffer. Controls the brightness of the bounced light
It combined ambient occlusion (micro-shadows in cracks and corners) with global illumination, preventing objects from looking like they were "floating" in the game world.
Reflections are calculated based on the environment. It executes entirely through standard compute shaders
This version refined the balance between diffuse lighting (soft color bounces) and specular reflections, allowing for more realistic metallic and wet surfaces.

Unlike SSAO, which simply darkens corners, RTGI calculates "color bleeding"—if a red car drives next to a white wall, the wall will actually take on a soft red hue, simulating light bouncing off the car surface. Installation and Setup (Context: 2021)
