The wasteland becomes genuinely post-apocalyptic. Sunlight bounces off sand dunes, and vault interiors look cold and metallic. Plus, it is less buggy than the game's native SSAO.
Native ray tracing operates on the geometry of the game world. It casts rays from the camera (or lights) that interact with 3D meshes and acceleration structures stored in the GPU memory. This allows for accurate reflections and lighting of objects that are not currently visible on the screen. reshade ray tracing shader rtgi 033 free
Conversely, the Reshade RTGI shader operates in the Post-Processing stage. It does not have access to the game's underlying 3D geometry. It only has access to the final 2D image rendered by the game engine. To simulate lighting, it utilizes a technique called Raymarching through the depth buffer.

Here is how to get RTGI 0.33 Free running in your favorite game (e.g., Skyrim, Fallout 4, GTA V, Elden Ring, or Cyberpunk 2077 for older GPUs). Native ray tracing operates on the geometry of
Final recommendation: Use the free v0.33 to test if you like the concept, but consider supporting the developer for the latest version.
GTA V’s native lighting is essentially last-gen (2013). RTGI adds bounce light from car headlights onto wet pavement and color bleed from neon signs. It feels like a remaster.
