Reshade Ray Tracing Shader | Rtgi 033
, which significantly improves the stability of the lighting during fast movement. Screen-Space Simulation
Think of RTGI as “intelligent screen-space ambient occlusion with color bleed.” It’s a cheat, but it’s a beautiful cheat.

If you’ve used RTGI v0.28 or v0.30, the changes in v0.33 are subtle but significant:
| 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. | , which significantly improves the stability of the
Keep the ray count between 3 and 5 for a balanced experience. Higher counts offer diminishing returns for heavy performance costs.
The sweet spot? with baked lighting. RTGI adds dynamic bounce light that those engines never had. Let me know your FPS hit below
Moving light sources interact seamlessly with static objects, altering shadows in real time. What Makes Version 0.33 a Critical Update?
Once activated, you will see 15+ sliders. Here is the optimal starting point for 1080p/1440p gaming.
: An RTX card is not required; the shader works on any modern GPU (Nvidia or AMD) as it relies on the depth buffer rather than dedicated hardware ray-tracing cores.
