Today, NVIDIA made its tech demo Zorah, A New Era of Rendering, available as a free 108 GB download. Built for Unreal Engine 5, Zorah shows off the sheer power of the new Blackwell architecture, led by the GeForce RTX 5090 and its neural rendering capabilities. After debuting the first version at CES 2025 and refining it at GDC, the company has now opened the doors for anyone with a fast connection and enough storage to explore it firsthand. Downloading the project takes about 15 minutes on a Gigabit link, after which you can fire up Unreal Engine 5 (available from the Epic Games Store) and dive straight into the demo. Once it's running, you'll find yourself in a scene built from nearly 500 million triangles, more than 30,000 materials, over 2,000 particle lights, and 1,500 textures. All of that horsepower would grind any GPU to a halt without NVIDIA's suite of neural tricks.
At the core of Zorah's performance are features like DLSS 4 with frame generation, a Transformer‑based AI model, and the full set of RTX Neural Shaders. These small neural networks run right inside the shaders, creating textures, materials, lighting volumes, and even hair detail in real time. Supporting tools such as RTX Texture Filter, Neural Material networks, Neural Texture Compression, Character Rendering, Neural Faces, Neural Hair, and Mega Geometry help round out the package, delivering visuals that look every bit as rich as big‑budget CGI. That level of efficiency shows how neural rendering can boost image quality and interactivity without hogging resources. NVIDIA hopes developers will experiment with these new tools and push game graphics into what the company calls a new era. If you have a modern RTX 5090 rig and a bit of patience, you can see that future for yourself. Click here to start the 108 GB download.
