0.36.1

Since version represents a specific point in the development of Pascal Gilcher’s (Marty McFly) RTGI shader, a paper on this topic would typically explore the technical intersection of screen-space ray marching and global illumination within a post-processing framework.

Overview

RTGI v0.36.1 adds realistic indirect lighting and bounce lighting to any DirectX 9–12, OpenGL, or Vulkan game. Unlike standard screen-space ambient occlusion (SSAO), RTGI traces rays in screen space to compute both occlusion and color bleeding from nearby surfaces. reshade rtgi 0361

ReShade RTGI (Ray Traced Global Illumination)

In the world of PC gaming, graphical fidelity is a never-ending race. While game engines get smarter every year, the hardware requirements often leave older or less optimized titles in the dust. Enter —a screen-space shader that simulates realistic light bouncing. Among the many iterations released by developer Pascal "Marty McFly" Gilcher, version 0361 has emerged as a landmark build. But what makes ReShade RTGI 0361 so special? Is it stable? Is it worth the performance hit? Noise: increase samples or temporal accumulation

What is RTGI v0.361?

• Noise: increase samples or temporal accumulation.
• Ghosting/Smearing: enable motion vectors or lower temporal blend.
• Light leaks across thin geometry: increase thickness/bias or use geometry-aware masking.
• Overbright spots (fireflies): enable clamping or lower max contribution.
• Loss of fine detail from aggressive denoising: reduce denoiser strength or edge smoothing.

• Depth Reconstruction: The shader reconstructs the 3D position of every pixel on the screen using the depth buffer and the camera’s inverse projection matrix.
• Normal Estimation: This is the most critical step. Since ReShade doesn't usually have access to the game's "Normal Buffer" (which way a surface is facing), RTGI must calculate it. It uses a Sobel operator or cross-plane difference on the depth buffer to estimate the surface normals.
• The Problem: This estimation is flawed at distance or with complex geometry, leading to "flat" lighting on round objects.
