Ultimate Guide to ReShade RTGI 0.33: Ray Traced Global Illumination Setup
is a special shader created for the ReShade post-processing tool. It was developed by Pascal "Marty McFly" Gilcher, a rendering engineer who has become one of the most famous names in the ReShade community.
Dynamic, soft shadows form naturally in corners, cracks, and crevices.
This is a limitation of screen-space ray tracing. The shader can only calculate lighting for objects currently visible on your screen. If an object goes off-screen, its light bounce disappears.
Set to 0.5 (Half Resolution). The internal denoiser will clean up the edges, saving you up to 30% in performance with minimal visual loss.
RTGI is available via Patreon (Pascal Gilcher) for a small monthly subscription ($5 or more). Once you subscribe, you gain access to the "full" stable build, including version 0.33. Alternatively, a free public version (often older like 0.29) exists, but it lacks the performance optimizations of 0.33.

When prompted to select shader packages to download, ensure you check and SweetFX by CeeJay.dk . Complete the installation. Step 2: Add the RTGI 0.33 Shader Files Extract your downloaded RTGI 0.33 zip file.
Extract the downloaded RTGI folder and copy the contents of the folders into the reshade-shaders directory in your game's installation folder. Configure Depth Buffer:
is a generic post-processing injector for games and video software. It allows you to add effects like bloom, HDR, and ambient occlusion to games that don't originally support them.
RTGI works with games that utilize . However, the shader absolutely requires access to the game's depth buffer to calculate depth and light bounces. Single-player games: Excellent compatibility.
: Models how light bounces off both matte and shiny surfaces, creating more realistic shadows and ambient light.
