Compared to earlier versions like 0.17 or 0.25, 0.36.1 offers vastly improved sampling accuracy and reduced "flickering" in high-contrast scenes.

represents a significant milestone in the evolution of real-time lighting for gaming. Developed by Pascal Gilcher (better known as Marty McFly ), this shader is a sophisticated post-processing tool designed to bring the visual fidelity of ray-traced lighting to almost any game, regardless of its original engine or age.

It does not require a dedicated ray-tracing (RTX) graphics card. It runs on the general processing power of any modern GPU that supports ReShade .

While newer versions like the iMMERSE Pro suite have since been released, version 0.36.1 is often cited by enthusiasts for its stability and specific calibration requirements.

It adds "color bleeding," where light hitting a colored object (like a red wall) naturally reflects that color onto surrounding surfaces. How to Install Reshade RTGI 0.36.1

Unlike hardware-native ray tracing (like NVIDIA RTX), which calculates light paths using physical world data, (Ray Traced Global Illumination) works within the screen space by analyzing a game's "depth buffer" to simulate how light bounces off surfaces. What Makes Version 0.36.1 Special?
