RTGI 0.3.3 offers a more accurate and efficient way to simulate global illumination in real-time. This technology allows for the creation of more lifelike environments by accurately capturing the way light interacts with the scene, including indirect lighting effects.
RTGI v0.33 is perfect for:
RTGI also use RT cores or benefit from DLSS (Deep Learning Super Sampling). It is a pure compute shader that runs on general‑purpose GPU cores, which is why it remains compatible with older hardware.
The result? Dark corners feel deeper, colored light bleeds realistically onto nearby walls, and your character no longer looks like they’re floating above the ground. reshade ray tracing shader rtgi 033
It achieves this through a technique known as . Unlike hardware ray tracing, which has access to the full 3D geometry of the game world, RTGI can only "see" what is currently being displayed on your monitor. The shader utilizes the depth buffer (information on how far away every pixel is from the camera) and the color buffer (the actual colors on screen) to construct a rough reconstruction of the visible 3D scene.
Controls the color bleeding effect. If a red character stands near a white wall, higher saturation forces more red light to reflect onto that wall. The Denoise Filter
: This is the headline feature for version 0.33. By utilizing motion vectors, the shader can track pixel movement between frames, significantly reducing "ghosting" or trailing artifacts common in previous versions. RTGI 0
This version shines in games with and few dynamic light sources :
Unlike newer pathtracers, v0.33 uses a technique. It is sensitive to quality settings.

The ReShade Ray Tracing Shader RTGI 0.3.3 represents a significant step forward in real-time lighting technology, offering users a powerful tool to enhance their gaming and 3D application experiences. With its balance of performance and visual fidelity, RTGI 0.3.3 is a valuable addition to any gamer's or developer's toolkit looking to push the boundaries of visual realism.
While native ray tracing (DXR) utilizes hardware-accelerated calculations based on the entire 3D scene,
stands as a landmark achievement in the history of PC graphics modding. By employing sophisticated screen-space path tracing algorithms, it managed to bring the visual complexity of Global Illumination to titles that were never designed for it. Despite requiring a subscription for the shader files and demanding substantial GPU power, it democratized ray tracing, allowing GTX 1060 users to experience lighting effects that were conceptually similar to those of flagship RTX cards. While later versions and alternative mods have improved performance and accuracy, version 0.33 remains the foundation upon which modern post-process ray tracing is built, and it continues to be the gold standard for a stable, well-documented ray tracing experience in ReShade.
