The RTX Global Illumination (RTXGI) SDK is now available. With the RTXGI SDK, game developers and artists can leverage the power of ray tracing to achieve multi-bounce global illumination without bake times, light leaks, or prohibitive run-time performance requirements.

RTXGI is supported on any DXR-enabled GPU, and is an ideal starting point to bring the benefits of ray tracing to your games and applications.

If you’re a developer, you’ll benefit from a fully managed data structure that supports any material and lighting model. The SDK provides optimized memory layouts and compute shaders, support for multiple coordinate systems, and hooks for engine and gameplay events to prioritize lighting updates.

If you’re an artist, you’ll be able to speed up your workflow significantly, thanks to real-time lighting updates in-game and in-editor. No UV parameterization or probe blockers are needed, and early access features provide automatic probe placement and dynamic performance optimization.

Key Highlights of the RTXGI SDK v1.0 release include: 

  • Full Source Code. We are providing full source code so you can easily integrate RTXGI into your tools and customize it to your specific needs.
  • No Baking, No Leaks. Dramatically speed up your iteration time with real-time ray traced lighting. No more waiting for bakes. No more obsessing over light probe positioning either; no light or shadow leaking.
  • Any DXR GPU. RTXGI runs on a broad range of hardware. All DXR-enabled GPUs are supported, including GeForce RTX 20 Series, GTX 1660 Series, and GTX 10 series.
  • Tuned & Optimized. Easy to integrate and fast to provide results, right out of the box. Performance optimized to fit in 60Hz frame budgets.
