Nvidia Zorah RTX neural rendering tech demo

Nvidia's Zorah showcases the latest advancements in neural rendering powered by GeForce RTX 50 series and AI.

Zorah is a large-scale Nvidia RTX neural rendering tech demo powered by Unreal Engine 5, designed to demonstrate the latest advancements in real-time rendering. Originally presented at CES 2025 and further refined for GDC, the demo is now publicly available as a 108 GB download.

It highlights key innovations in geometry processing, lighting, character rendering, and neural shader technologies, and is intended for developers and researchers working with next-generation graphics pipelines.

Note: The download is packaged as an Unreal Engine project, not an executable. Requires you to install Unreal Engine first.

The project runs on the Nvidia RTX branch of Unreal Engine 5 (NvRTX) and is optimized for the GeForce RTX 5090, utilizing features from the Blackwell architecture. Zorah includes scenes composed of nearly 500 million triangles, over 30,000 materials, more ...
