Enable the RTGI shader in the main list. Adjust the Ray Length to match the scale of the game world, and fine-tune the Amount slider to blend the global illumination naturally with the original art style. Compatibility and Visual Impact
Software-based ray tracing strains the GPU. The developer rewritten core parts of the underlying code to utilize modern GPU architectures more efficiently. Users report a 10% to 15% frame rate improvement compared to the early 0.16 builds, making 60 FPS gameplay much more achievable on mid-range graphics cards. Performance Impact: What to Expect
The RTGI project has been actively developed over the past few years, with a team of dedicated researchers and engineers working tirelessly to push the boundaries of real-time lighting. The project has seen several significant releases, each bringing incremental improvements and new features to the table. The latest release, RTGI 0.17.0.2, marks a major milestone in this journey, offering a plethora of enhancements that solidify its position as a leading solution for real-time global illumination. rtgi 0.17.0.2 release
Installing 0.17.0.2 (concise steps)
RTGI, or Real-Time Global Illumination, is a technology that enables the rendering of accurate, dynamic lighting in real-time applications such as video games, simulations, and interactive experiences. This is achieved through a combination of advanced algorithms, data structures, and software techniques that simulate the way light behaves in the real world. Enable the RTGI shader in the main list
To capitalise on this, the sample counts for all quality settings were reduced without any visual loss. The result was a significant performance gain, essentially providing "performance for free" as Gilcher put it. This meant that users could run the shader at higher quality presets or on weaker hardware and still enjoy smooth gameplay, a massive win for accessibility.

Surfaces now interact realistically with ambient light based on their material properties. Matte surfaces diffuse light softly across a wide area, while glossy materials exhibit sharper, localized reflections. Infinite Bounces Simulation
