The impact of RTGI on game development has been profound. It allows for:
Whether you’re a gamer, a 3D artist, or a modder, you can get true RTGI right now for . Here is your complete guide.

As computational power continues to grow and algorithms become more efficient, the future of RTGI looks bright. We can expect to see:
Ray Traced Global Illumination (RTGI) simulates how light bounces off surfaces in a 3D environment. Traditional game lighting is often "baked" (pre-rendered), which makes environments look flat. RTGI calculates indirect lighting in real-time, meaning light from a fire will properly illuminate a wall, and bright sunlight will make colors bleed onto nearby surfaces. No plugins
Screen Space Global Illumination (SSGI) shader included in the qUINT_SSGI suite. It’s not ray traced, but it fakes light bounces incredibly well at zero performance cost.
