RTGI (Ray Traced Global Illumination)

The ReShade shader, specifically version 0.36.1 , represents a peak in community-driven graphics enhancement, bridgeing the gap between aging game engines and modern lighting technology. Developed by Pascal Gilcher (Marty McFly), this shader uses screen-space information to simulate complex light bounces and shadows that were never originally programmed into the games. Why RTGI 0.36.1 is a Major Leap

• Quality Mode: Extra (not Ultra – that’s for 0.372+)
• Use High Precision Buffer: On (reduces banding)
• Temporal Accumulation: 0.850 – 0.920 (lower = less ghosting but more noise)
• Denoising Passes: 2 (default for Extra)

Color Bleeding:

If you stand next to a red wall in-game, your character’s armor should catch a subtle red tint. The 0.36.1 version improved the accuracy of this effect, preventing the "glow" look and replacing it with realistic light transfer.

• Saturation: 1.0 (neutral) or 1.2 for vibrant color bleeding
• Luminance Threshold: 0.05 (lower = darker areas receive more bounce)

• Ghosting / Trailing

  In the pursuit of photorealism in PC gaming, few technologies have caused as significant a shift in visual fidelity as Ray Tracing. However, for years, the benefits of Ray Traced Global Illumination (RTGI) were locked behind expensive hardware requirements and specific game engines. That changed with the advent of Reshade RTGI.
