RTX Global Illumination (RTXGI)

Fast multi-bounce indirect lighting has never been easier.

RTXGI's probe-based data structure temporally accumulates and filters lighting and distance information in real time, creating a high quality multi-bounce lighting cache with visibility information.

Strict frame budget? RTXGI provides an ideal balance between quality and performance for real-time applications with tight frame budgets through a low frequency approximation of the full path tracing process.

Infinite Bounce Lighting in Real Time

Content Creation at the Speed of Light

Accelerate your tools, pipeline, and artist workflows.

With RTXGI, the long waits for offline lightmap and light probe baking are a thing of the past. Artists get instant results in-editor or in-game. Move an object or a light, and global illumination updates in real time.

Decrease iteration times by cutting out time spent tuning light probe positions. No light or shadow leaking, right out of the box, without obsessing over probe placements.

Full source code puts you in control.

Customize RTXGI to your needs on any DXR-enabled GPU, including the GeForce RTX 30 series, RTX 20 Series, GTX 1660 Series, and GTX 10 series. RTXGI's scalable design gives you the control to decide when and where you want to crank up performance or max out image quality.
