2. The demo runs on Unreal Engine 5 and utilizes Nvidia’s RTX 5090 to achieve nearly photorealistic visuals with realistic lighting and shadows.
3. An updated version of the demo was released on March 13, receiving praise for its artistic quality, though concerns about its practical application in gaming remain.
4. A preview of the DirectX 12 Agility SDK supporting neural rendering will be available in April through a partnership with Microsoft.
5. Nvidia plans to release Unreal Engine 5 plugins for developers, but the timeline for implementing this technology in game development is still uncertain.
Nvidia has introduced an innovative tech demo named “Zorah,” which highlights the power of neural rendering. This AI-based technology is designed to boost efficiency in handling complex graphics by substituting traditional shaders with trained neural networks. The aim is to enhance image quality while simultaneously improving performance. Additional insights can be found in a blog post from Nvidia.
Tech Demo Features
The Zorah tech demo operates on Unreal Engine 5 and has been specifically crafted utilizing Nvidia’s unique RTX branch (NvRTX), a specialized version of the engine. It is powered by the latest RTX 5090, which is the flagship model in the 5000 series, striving to provide visuals that are nearly photorealistic, complete with authentic lighting and shadow effects. Nvidia first demonstrated this technology back in January:
Recent Updates
On March 13, an updated iteration of the tech demo was unveiled, showcasing even greater detail:
YouTube users have lauded the artistic quality and visual excellence of the tech demo. Nonetheless, its stationary nature has led to questions about whether these advancements are truly ready for integration into game development. Some commenters have humorously noted potential low frame rates, making remarks like ‘RTX 5090: 17 FPS’ or ‘Without DLSS: 4 FPS.’
Future Collaborations
In partnership with Microsoft, a preview edition of the DirectX 12 Agility SDK that supports neural rendering will be launched in April. Nvidia also plans to provide various Unreal Engine 5 plugins for developers. However, it is yet unclear when and how this cutting-edge technology will be utilized in the realm of game development.
