: Unlike native RTX, RTGI works on non-RTX cards (GTX, AMD) because it uses the game's depth buffer rather than dedicated hardware cores. 2. Installation Steps
This is a paid shader. You must have the files ( qUINT_rtgi.fx and textures) from Pascal Gilcher’s Patreon.
Version 0.33 refined the approximation of secondary and tertiary light bounces. If a character stood next to a bright red wall, the red light naturally reflected onto their clothes. reshade ray tracing shader rtgi 033 2021
With the release of their shader in 2021, RTGI_033's hard work paid off. The graphics community was abuzz with excitement as users began to share their experiences with the ReShade RTGI shader. Suddenly, games and applications that previously lacked luster were transformed, boasting more realistic lighting, reflections, and shadows.
Move these files directly into your game’s directory where ReShade installed its folders (usually game_directory/reshade-shaders/ ). Step 3: Configure the Depth Buffer : Unlike native RTX, RTGI works on non-RTX
Setting up RTGI 0.33 requires a specific workflow to ensure the depth buffer functions correctly.
: Light takes on the color of the surfaces it reflects from, creating realistic ambient lighting. You must have the files ( qUINT_rtgi
The 0.33 iteration of RTGI focused heavily on balancing visual fidelity with hardware performance.
The shader can only calculate lighting for objects visible on your screen. If a bright light source goes behind your camera view, its bounce light will disappear.
If a bright red car sits next to a white wall, RTGI calculates the light reflecting off the car, accurately "bleeding" red light onto the wall.
By 2021, the ReShade community had accepted RTGI as the definitive lighting enhancement tool. Version 0.33 became a "must-have" and a "stable baseline" for mod creators, and it was specifically recommended for new presets because it was both reliable and widely available.
