Reshade Rtgi 0.36.1 💫

Reshade RTGI 0.36.1 (Ray Traced Global Illumination) is a highly sought-after shader developed by Pascal Gilcher (Marty McFly). It brings real-time ray-traced lighting, shadows, and reflections to almost any DX9, DX11, DX12, or Vulkan title, drastically improving visual fidelity without requiring native engine support.

Step-by-Step Installation Guide

Installing RTGI 0.36.1 is more involved than a modern ReShade preset. You need the specific shader files, which are often hosted on the ReShade forum or the author’s Patreon (the free version is usually available after a delay). Reshade Rtgi 0.36.1

• Custom passes: you can chain RTGI with other Reshade shaders (e.g., SSR, AO, Bloom). Order matters: run RTGI before bloom and after primary tonemapping depends on desired look—commonly run RTGI early enough to affect lighting but after the main scene pass.
• LUTs & Color grading: apply final LUT after RTGI combine pass so GI contribution is color-corrected consistently.
• Multiply with ambient occlusion: combine AO and RTGI carefully—AO is darkening contact shadows while RTGI adds indirect light; stacking both with excessive strength can over-darken.
• Scripted presets: create separate presets for gameplay vs screenshots, switching RTGI parameters or disabling it automatically.
• Use AI upscalers (DLSS/FSR) for full game to offset RTGI cost; alternatively, run RTGI at lower resolution and upscale it.

ReShade RTGI version 0.36.1, developed by Pascal Gilcher, transitioned into the iMMERSE Pro suite in early 2024, focusing on performance optimizations and improved denoising. This update enhanced temporal filtering to reduce ghosting and introduced simplified modes for better performance on mid-range hardware.

Best Practices for Different Game Genres

First-person games (Fallout 4, Bioshock, Dishonored)

• Use Radius: 0.5 – 0.7 to keep lighting local.
• Set Temporal Amount: 0.8 – reduces noise without heavy ghosting when turning quickly.
• Pair with MXAO (Medium preset) to fill in fine crevices.

Conclusion

RTGI (Ray Traced Global Illumination) is a post-processing shader that adds dynamic, realistic lighting to games by simulating how light bounches off surfaces. Unlike native RTX, it uses Screen Space Ray Tracing. It relies on the game’s "depth buffer" to understand the 3D layout of a scene and calculate indirect lighting and ambient occlusion.
