Reshade Ray Tracing Shader Rtgi 033 Instant

Prior versions of RTGI were highly susceptible to "shimmering" or aggressive visual noise when the camera moved quickly. Version 0.33 specifically resolved these historical pain points through two core features:

: Higher values improve quality but significantly impact FPS. reshade ray tracing shader rtgi 033

True global illumination requires light to bounce multiple times across a room. Version 0.33 utilizes an optimized math model to simulate secondary and infinite light bounces. If a bright red light hits a white floor, the red tint will realistically bounce up onto the ceiling and nearby walls, creating an incredibly cohesive atmosphere. 3. Infinite Thickness Dynamic Depth Tracing Prior versions of RTGI were highly susceptible to

| Setting | Effect | |:--------|:-------| | | Controls the number of ray steps and samples. Higher values produce more accurate illumination but increase GPU load. Options typically range from “Low” to “Ultra”. | | Resolution | The internal resolution at which rays are traced. “Full” gives the best quality; “Half” or “Quarter” significantly improve performance at the cost of some precision. | | Intensity | How much bounce lighting is added. Values around 0.3 – 0.8 are subtle and natural; values above 1.0 create dramatically over‑lit scenes. | | Bounce | Number of times light can reflect between surfaces. Higher values produce more realistic indirect illumination but increase noise and GPU cost. 2–3 bounces is a good balance. | | Luminance | Affects how bright light sources are interpreted. Raising this value can make lights bleed more aggressively into dark areas. | | Radius | The maximum distance over which light bounces are evaluated. Lower values limit the effect to nearby surfaces (faster), higher values allow long‑range illumination (slower). | | Fade Start / Fade End | Define at what distance the RTGI effect smoothly fades out. Useful for keeping distant objects from becoming unnaturally bright. | | Depth Tolerance | Determines how aggressively the shader differentiates between foreground and background objects. Adjust this if you notice light “leaking” through thin walls or around occluders. | Version 0

It is important to understand the limitations of ReShade RTGI v0.33. Unlike native DXR (DirectX Raytracing) or Vulkan Ray Tracing, which have access to the full 3D geometry of the scene, ReShade only sees what is on the screen (the 2D image and depth buffer).
