Real-Time Global Illumination: How to Get RTGI Shaders for Free

Disable Anti-Aliasing (MSAA/FXAA) in your game's video settings, as native anti-aliasing can sometimes block ReShade from reading depth data. Performance Impact and Optimization

Screen-space ray tracing is demanding. Because it calculates lighting based on your resolution, you will experience a drop in frames per second (FPS).

, you can access several high-quality free alternatives that provide similar ray-traced lighting and global illumination effects. Top Free RTGI Alternatives

To use an RTGI shader, you first need , a generic post-processing injector.

This comprehensive guide covers how RTGI shaders work, where to find legitimate free downloads, and how to optimize them for the best performance. What is an RTGI Shader? Real-Time Global Illumination: How to Get RTGI Shaders

A highly optimized, completely free shader available on GitHub.

Searching for "rtgi shader free download free" will yield mixed results. The best, most up-to-date version of the RTGI shader is a paid product by Pascal Gilcher. However, free alternatives exist within the standard ReShade shader packs, and older versions of the shader can sometimes be found on GitHub or Discord.

This is a community-driven, public ray tracing shader for ReShade designed to be a free alternative to paid versions. DHYCIX/RTShade on GitHub . 3. NVIDIA's Free Version (SSRTGI) | Source Type | Probability of Malware |

During the installation, ReShade will ask which shader packs you want to download.

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.

Unlike many community mods, Marty McFly’s RTGI shader was placed behind a on Patreon , typically requiring a $5/month "Beta tier" membership to access.

Turn off in your game's video menu, as it breaks the depth buffer.

Look for or the dedicated qQUINT repository, which contains optimized lighting and ambient occlusion shaders.
