: A feature in newer versions that allows light to bounce multiple times, creating much more realistic interior lighting.
Depending on your GPU and the number of rays, you might see a 10%-30% performance drop, but for slower-paced, atmospheric games, it is well worth the cost.
While many games have basic shadowing, RTGI provides much deeper, more accurate ambient occlusion. This means shadows in crevices, corners, and where objects meet are darker and more defined, adding significant depth and realism to the game world. Users have noted that RTGI made a big difference in titles that "lack good Ambient Occlusion" or have "weak shadows". Reshade Ray Tracing shader RTGI 0.33
Before you touch the settings, you must set the stage, or the shader will look flickery or "noisy."
This is the core of the shader. It simulates how light from a primary source (like the sun or a lamp) hits a surface and then scatters onto other surfaces, creating realistic bounced lighting. For instance, a sun-exposed wall will subtly illuminate the area next to it, creating a more natural and immersive visual experience. : A feature in newer versions that allows
Choose the rendering API the game uses (DirectX 9, 11, 12, or Vulkan).
I’ve written this for a typical PC gaming/graphics enthusiast blog — informative, slightly technical, but not overly academic. This means shadows in crevices, corners, and where
If light changes abruptly when you rotate your camera, your depth buffer settings are likely inverted. Look at the bottom of the ReShade UI, click , and change RESHADE_DEPTH_INPUT_IS_REVERSED from 0 to 1 (or vice versa). RTGI Shines Through In-Game Menus or HUDs
