Reshade Ray Tracing Shader Rtgi 033 Jun 2026

Standard game engine lighting often relies on static lightmaps or simplified ambient occlusion (like SSAO or HBAO) which leaves corners unnaturally dark or uniformly lit. RTGI 0.33 calculates how light from a primary source (like the sun or a torch) bounces off a colored surface and illuminates the surrounding environment. If a character stands next to a bright red wall, a subtle red tint will naturally bleed onto their clothing. 2. Screen Space Ray Traced Reflections and Shadows

: Version 0.33 features a more "stable" denoiser, reducing the "flickering" or "boiling" effect common in older screen-space implementations.

The 0.3.3 version of the shader brought improvements in performance and stability compared to earlier versions, making it more accessible to users with mid-range hardware.

Gilcher has also introduced a high‑end path‑traced volumetric fog shader, currently available only to the highest tier (“Photon Mappers”) of his Patreon at $20 per month. Standard game engine lighting often relies on static

Launch your game, then press the key (or the key you assigned during ReShade installation) to bring up the ReShade overlay. If this is your first time, click through the brief tutorial.

Given the recent updates to RTGI and the existence of alternatives, it is valuable to understand how 0.33 compares to newer solutions. In the Reshade overlay (Home key)

RTGI 0.33 can cut your framerate by 20% to 50% depending on your configuration. Use these optimization configurations to reclaim performance:

: RTGI requires access to the game's Depth Buffer to work. In the Reshade overlay (Home key), ensure the "DisplayDepth" shader looks correct (smooth gradient from black to white). Configuration : Ray Length : Adjusts how far the light travels.

It is important to understand what RTGI does—and does not—do, especially when comparing it to a game’s built‑in ray tracing.
