Simulates realistic light distribution and multi-bounce lighting.

Pascal Gilcher is a German shader developer and one of the most influential ReShade modders. His breakthrough was the shader, which appeared in May 2019. The effect became so popular that NVIDIA eventually integrated it into GeForce Experience Freestyle as “SSRTGI”.

Native ray tracing calculates light rays across an entire 3D world map, which requires massive hardware power. RTGI uses a smarter, highly optimized shortcut: .

The RTGI (Ray Traced Global Illumination) shader from Marty McFly, also known as Pascal Gilcher, has become one of the best-known ways to upgrade a game’s lighting and atmosphere without waiting for an official patch. This article covers the unique position of version within RTGI’s evolution, including how it compares to newer builds and why it can be the ideal starting point for players on mid-range systems.

For a high‑end card you can push quality to the max; on a mid‑range GPU you can drop quality to maintain 60 FPS while still getting better ambient occlusion than the game's native shading.

: This version improved the shader's ability to guess the thickness of objects it can't "see" behind, reducing the "ghosting" or halo effects that often plague screen-space effects. Technical Limitations

Apply to any third-person or FPS game from 2010–2018. Adjust Radius down to 0.5 for interiors, up to 1.0 for exteriors.

Adding full‑screen ray tracing inevitably costs performance. In Hogwarts Legacy , one user tested RTGI 0.36.1 and reported that GPU usage increased to 100%, yet frame rates remained stable and turning the camera no longer produced stutter. In that test, the user replaced the game's native ray tracing with RTGI and observed including GTX 1080 and RX 5700.

Controls how bright the bounced light is. If the game looks washed out, lower this setting.
