Installing RTGI involves two main parts: installing ReShade itself, and then adding the RTGI shader files. Below is a detailed walkthrough.
(e.g., RTXGI, DXR) uses the actual 3D geometry of the scene, stored in acceleration structures like bounding volume hierarchies (BVH). It can produce physically accurate illumination, shadows, and reflections, and it typically leverages dedicated RT cores in modern GPUs to accelerate BVH traversal.
When DisplayDepth is active, you should see the left half of the screen in a colourful, heat‑map style, and the right half in greyscale. If you see this, the depth buffer is already correctly detected. If the screen is or shows only colours/greyscale on the wrong side , proceed to the next step.
You cannot find RTGI 0.33 on the official ReShade shader repository (Shadez) anymore. You must find the legacy archive (usually hosted on GitHub or community forums).
Fine details, clothing folds, and geometry intersections receive realistic micro-shadows that ground objects in the environment.
: In-game, open the ReShade menu (usually the Home key) and enable qUINT_rtgi Copy Depth Buffer
In the Home tab, scroll through the effect list until you find DisplayDepth (sometimes labelled DebugDepth ). Enable it by ticking its checkbox. This replaces your game view with a visualisation of the depth buffer.
