It is important to manage expectations regarding hardware. While this is a "shader," it is computationally expensive.
Ensure ReShade has access to your game’s depth buffer (disable MSAA in-game). In 2021, the gaming industry was in the
If your shadows look "floaty," decrease the ray length. If the lighting feels too local, increase it. 🎮 Final Verdict
| Parameter | Function | | :--- | :--- | | | Maximum distance a ray travels to find a surface. Higher = more bounce light but more performance cost. | | Intensity | Strength of the indirect lighting contribution. | | Bounce Count (Hidden) | Fixed in v0.33 to 1-2 bounces for performance reasons. | | Temporal Factor | How much the current frame blends with previous frames to reduce noise. | | Quality Mode | Low (performance) vs. High (visuals). High used 4 rays per pixel. | | AO Mix | Blends traditional ambient occlusion with ray traced AO for cleaner shadows. | Run the installer, select your game's
is a ReShade shader that approximates the visual effects of hardware-accelerated Ray Tracing (like DLSS or DXR) on almost any game, even those that don't natively support it.
In games like The Witcher 3 or Skyrim , RTGI 0.33 transforms the atmosphere by adding moody lighting and natural, soft-shadowed,, ambient occlusion, making the world feel tangible.
