Caption: Finally got my hands on the new RTGI 0.33 update for ReShade. 🤯

The improvements to temporal stability are a game-changer—no more shimmering while moving the camera. The lighting feels so much more natural and grounded now. It’s crazy what a shader can do for immersion in games that are years old. reshade ray tracing shader rtgi 033

RTGI stands for Ray Traced Global Illumination. In traditional game rendering (rasterization), lighting is often "baked" into the textures or simulated via pre-placed light sources that don't naturally bounce. A light source illuminates a wall, but the light doesn't bounce off that wall to illuminate the floor.

RTGI solves this by calculating how light bounces around a scene in real-time. It simulates how light behaves in the real world: colors bleed onto nearby surfaces (color bleeding), shadows become softer and more realistic the further they get from the object (contact hardening shadows), and ambient light feels natural rather than flat.

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).

  • When asked to select effect packages: Uncheck everything. You will manually add RTGI.
  • Click Install. This creates the ReShade DLL and the ReShade.ini file.

    • RTGI stands for Ray-Traced Global Illumination. Unlike traditional screen-space ambient occlusion (SSAO) or even static lightmaps, RTGI simulates light bouncing off surfaces. It analyzes the depth, color, and normal vectors of the scene in front of your camera and then casts rays to approximate where light would scatter.

    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.

    Version 0.33 isn’t a revolutionary rewrite—it’s a refinement of the shader that first dropped in 2020. But those refinements matter. Skip it if:
