Reshade Ray Tracing Shader Rtgi 0.33 High Quality -
Stands for Ray Traced Global Illumination . This is the specific shader made by developer Pascal “Marty McFly” Gilcher . It bounces light in screen space to simulate indirect lighting, making shadows and colors look more natural.
Unlike native Nvidia RTX or AMD DXR, which require access to a game's underlying engine code and geometry data, RTGI utilizes the of the game. It reads the 3D depth map of what is currently visible on your screen and casts rays across those surfaces.
A upgraded temporal filter blends frames smoothly to eliminate the "grainy" look of earlier versions. Installation Requirements
Turn off SSAO, HBAO, or CACAO in your game's native graphics menu. RTGI completely replaces these features, saving you valuable processing power. Reshade Ray Tracing shader RTGI 0.33
Launch the game and press the (or Pos1 ) key to open the ReShade overlay. Check the box next to qquint_rtgi to enable the shader. Fine-Tuning RTGI 0.33 for the Perfect Balance
: Download the latest version from the official ReShade website . 2. Installation Steps
Screen-space ray tracing has revolutionized PC gaming graphics. Pascal Gilcher’s Screen-Space Ray Traced Global Illumination (RTGI) shader for ReShade allows players to add realistic lighting, ambient occlusion, and reflections to almost any 3D game. Version 0.33 introduces critical performance optimizations, better temporal stability, and refined user controls. Stands for Ray Traced Global Illumination
: By using motion vectors, the shader can track how pixels move from frame to frame. This drastically reduces the "ghosting" or flickering often seen in older screen-space effects.

RTGI 0.33 reads the scene's bright areas (like skies or neon signs) and treats them as dynamic light sources. If you are standing under a bright blue virtual sky, your character's shoulders and top surfaces will subtly inherit a blue tint, blending assets perfectly into their environment. Step-by-Step Installation Guide Unlike native Nvidia RTX or AMD DXR, which
While RTGI runs on standard hardware (unlike hardware-accelerated RTX), it is highly demanding. A mid-range or high-end GPU is recommended.
Drop the RTGI 0.33 shader files: copy the .fx files into the Shaders folder, and the .fxh (header) files into the Textures or Shaders folder as specified by the shader documentation. Step 3: Configure the Depth Buffer
Because this shader runs at the post-processing level inside ReShade, it does not require dedicated RT cores. You can run RTGI 0.33 on Nvidia GTX cards, AMD Radeon RX cards, and even modern integrated graphics, provided the GPU has enough raw compute power. How to Install Reshade RTGI 0.33
