ReShade Ray Tracing Shader RTGI 0.3.3 Exclusive: A Comprehensive Write-up

Part 3: Step-by-Step Installation Guide

Before we begin, you need ReShade version 5.9.2 or newer. RTGI 0.33 does not work on ReShade 6.0+ without a compatibility patch. reshade ray tracing shader rtgi 033 exclusive

Known Issues & Fixes

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Black screen or no GI | Wrong ReShade version | Use 4.9.1, not 5.x | | Flickering/boiling light | Screen-space + no denoiser | Increase ray length, lower intensity, or accept as style | | GI only near screen center | Screen-space artifact | Turn camera or accept limitation | | Crashes on launch | Depth buffer access | Enable Copy depth buffer before clear in ReShade settings | | Objects glow incorrectly | Incorrect depth buffer | Use DisplayDepth shader to debug; adjust Depth Buffer in ReShade add-ons | ReShade Ray Tracing Shader RTGI 0

• Two approaches:
  • This code uses HLSL (High-Level Shading Language) for DirectX.
  • It assumes that the input textures (g_texDepth, g_texNormal, and g_texAlbedo) are bound to the correct texture slots and are in the same space as the compute shader.
  • The g_rwOutput texture is used to store the ray tracing output.
  • The RTGIParams buffer stores the parameters for the RTGI algorithm, such as ray length, minimum ray length, intensity, and number of samples.

  . This allows the shader to track object movement between frames, significantly reducing the "ghosting" or trailing artifacts common in previous versions when things moved quickly across the screen. Enhanced Temporal Stability: Two approaches:
