Enable the internal temporal denoiser inside the RTGI UI. It pools data across multiple frames, giving you smooth ray tracing at lower sample settings.
Ray tracing is inherently "noisy" because it is impossible to calculate an infinite number of rays in real-time. Version 0.33 introduced a more robust temporal denoiser that uses information from previous frames to smooth out the graininess without causing the "ghosting" effects seen in earlier iterations.
RTGI requires access to the game’s depth map. Games with anti-cheat software (like Valorant or Destiny 2 ) will disable the depth buffer entirely to prevent wallhacking, making RTGI incompatible with competitive multiplayer titles. 3. Step-by-Step Installation Guide Follow these steps to integrate RTGI 0.33 into your game:
A major addition in 0.33 is the utilization of motion vectors, which significantly improves the temporal stability of the lighting.
Navigate to your game’s root directory (where the .exe is located). You should see a folder named reshade-shaders . Reshade Ray Tracing shader RTGI 0.33
A toggle feature in RTGI 0.33 that simulates multiple light bounces using an algorithmic cache. Enabling this adds substantial depth to shadows and light bleeding, closely matching native hardware path-tracing. 6. Performance Optimization and Troubleshooting
To check if RTGI is reading the scene correctly:
RTGI 0.33 accurately models both diffuse (soft, bounced light) and specular (shiny reflections) global illumination. How RTGI Transforms Your Game
⚠️ Note: While it works on many cards, ray tracing is inherently demanding. As Marty McFly puts it, using it on "a toaster" is not recommended. Enable the internal temporal denoiser inside the RTGI UI
Version 0.33 was a "golden era" release, known for stability. However, more recent updates (0.36+) have built upon 0.33’s foundation with massive leaps. Here is what RTGI brings to the table, covering the 0.33 release as well as the future evolutions of the shader.

True ray tracing calculates light bouncing infinitely around a room. RTGI 0.33 uses highly optimized mathematical approximations to simulate secondary and tertiary light bounces. If a bright red laser shines on a white wall, the white wall will realistically cast a soft red glow onto the floor beneath it. 2. Enhanced Denoising Filter Version 0
It can only calculate lighting for objects currently visible on your screen. If a light source or an object is behind the camera or off-screen, it cannot contribute to the lighting.
: Simulates multiple light bounces, allowing color from a bright floor to reflect onto a wall, and then onto the ceiling.
For years, the PC gaming community has been split into two distinct camps: those who own an expensive NVIDIA RTX GPU and can toggle "Path Tracing" in Cyberpunk 2077 , and those who rely on raw rasterization power, hoping for a slice of that visual fidelity pie.
