Updated - Reshade Rtgi 0.36.1

The update for ReShade, developed by Pascal Gilcher (Marty McFly), focuses on significant architectural improvements to his "Ray Traced Global Illumination" shader. This version serves as a bridge toward the modern iMMERSE Pro suite, refining how the shader handles light bounces and screen-space data to approximate high-end ray tracing on almost any GPU. Overview of ReShade RTGI

Unlike native ray tracing (e.g., Cyberpunk 2077’s RT or NVIDIA RTX), RTGI does know whether a surface is wet, rough, metallic, or translucent. It assumes all surfaces behave similarly. Some users have noted that RTGI can darken corners too much or brighten areas that should remain shadowed. The effect is a lighting approximation , not a physically accurate simulation.

After installing, bind "Toggle RTGI" to a key (e.g., F9 ). Turn it on and off while standing inside a dim room near a doorway. Watch the sunlight bounce onto the ceiling behind you. That moment—that subtle, free upgrade—is why 0.36.1 remains a legend.

: The game must allow ReShade to "see" the depth map. You may need to disable in-game Anti-Aliasing (MSAA) for this to work.

The first step is to download the ReShade installer from the official website. Ensure you select the version compatible with your system. Reshade Rtgi 0.36.1

Because it operates as a post-processing shader through ReShade, it uses the game’s to calculate light vectors. This means you can add realistic color bleeding, soft ambient occlusion, and dynamic micro-shadows to titles released well before the ray-tracing era. Key Features in Version 0.36.1

Adjust the slider. Lower values reduce noise but increase ghosting behind moving objects. Find a middle ground around 0.40 . 3. Material Properties
