Reshade Ray Tracing Shader Rtgi 033 Exclusive May 2026

| 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 |

Because you are using an archived, exclusive version, you will encounter bugs. Here is how to fix them.

  • Edge-preserving weights: w = exp(-|d_depth|/sigma_z - ||d_norm||^2/sigma_n - ||d_albedo||^2/sigma_c).
  • For specular/glossy indirect, apply stronger spatial filtering along roughness.
  • Cause: The depth buffer is flipping. Fix: In Add-ons, check "Reverse depth buffer" . Also, ensure your game is not running in "Windowed Borderless" mode. Exclusive tip: Force "Fullscreen Exclusive" mode via Windows Graphics Settings.
