Check the box for your game's resolution under the generic depth plug-in.

Softer, more realistic shadows based on light sources.

If you are looking for specific standalone versions of the Ray Tracing features:

If your game supports upscaling technologies like Nvidia DLSS or AMD FSR, turn them on. This offsets the performance cost of the heavy screen-space calculations. rtgi shader free download free

While Pascal Gilcher maintains a Patreon for the latest updates, older builds and standard RTGI shaders are available in the public ReShade shader repository.

Uses dedicated GPU cores (RTX or RX cards) to calculate light across an entire 3D world. Check the box for your game's resolution under

The most famous RTGI shader was created by developer Pascal Gilcher (McFly).While early beta versions were locked behind a Patreon subscription, older stable builds and alternative open-source ray tracing shaders are widely available for free. 1. Pascal Gilcher’s RTGI (Legacy Free Versions)

In the shader parameters at the bottom of the ReShade menu, reduce the sample amount. This degrades the quality slightly but recovers substantial FPS.

Go to the or DX12 tab in ReShade and check the box to enable the depth buffer. This offsets the performance cost of the heavy

| Feature | Free RTGI (v0.17) | Paid RTGI (v0.25) | | :--- | :--- | :--- | | | 40-50% FPS loss | 15-25% FPS loss | | Flickering | High (noisy) | Low (stable) | | Setup Difficulty | High (manual tweaking) | Medium (auto-config) |

Why pay for it? The development log for June 2025 revealed that the new RTGI algorithm significantly outperforms NVIDIA’s state-of-the-art ReSTIR GI algorithm without suffering from typical drawbacks like chroma noise or white noise output. Additionally, reflections now use HiZ Min-Max Tracing for precise path tracing.

Ray Tracing Global Illumination (RTGI) transforms video game graphics by simulating how light bounces off surfaces. While official ray tracing often requires expensive hardware, software-based RTGI shaders allow players to experience next-generation visuals on existing systems.

Simulates actual light rays as they bounce from one object to another. If you stand next to a red wall, the light hitting your character’s shoulder will have a subtle red tint. It adds a level of depth, realism, and "groundedness" that standard shaders can't match. Can You Get the RTGI Shader for Free?
