Run the installer and select the target game’s executable (.exe) file.
Launch the game and press the key to open the ReShade overlay.
Navigate to your game’s root folder. Locate the reshade-shaders folder. Inside, you will usually find a Shaders subfolder and a Textures subfolder. Copy and paste the qUINT_RTGI.fx and associated texture files from your downloaded folder directly into the Shaders folder of the game.
: Simulates multiple light bounces, allowing color from a bright floor to reflect onto a wall, and then onto the ceiling. Reshade Ray Tracing shader RTGI 0.33
While earlier versions focused on diffuse light, later iterations (following the 0.33 lineage) introduced "HiZ Min-Max Tracing" for reflections. This allows the shader to trace "pixel-perfect paths" for specular reflections, making shiny surfaces look sharp.
The shader transforms scenes by adding depth and realistic color interaction. Global Illumination:

If your frame rate takes too heavy of a hit, use these optimization strategies to recover performance without sacrificing the ray-traced look:
RTGI provides a much more accurate form of ambient occlusion than standard SSAO, adding weight to corners and the intersection points of objects. Visual Artifacts: Despite improvements, RTGI is limited by being a screen-space effect Locate the reshade-shaders folder
While it runs on non-RTX cards (including GTX and AMD Radeon hardware), it is incredibly demanding. Expect a performance hit ranging from 20% to 50% depending on your settings. Step-by-Step Installation Guide Step 1: Install ReShade
Complete the initial tutorial, then navigate to the tab in ReShade.
In version 0.33, enabling the temporal accumulation limits allows you to lower raw ray counts while maintaining smooth, noise-free lighting over time.
