Nvidia officially released Zorah to the public this week. Zorah is a small game (demo) that demonstrates the capabilities of the GeForce RTX 50 Series graphics processing unit (GPU). Previously, Zorah was revealed by the American chip company at the Consumer Electronics Show (CES) 2025 in January and the Game Developers Conference (GC) 2025 in March. Zorah was created using the Unreal Engine 5 (UE5) application which is equipped with additional Nvidia features called Nvidia RTX (NvRTX). NvRTX comes with a number of supporting technologies typical of the RTX 50 Series GPU. One of them is RTX Neural Shaders which allows artificial intelligence (AI) technology to improve the quality of objects and materials in the game environment.
There is also RTX Neural Radiance Cache (NRC) which can speed up the lighting rendering process in the environment, as well as RTX Neural Texture Compression so that the graphics rendering process can be efficient, but still "friendly" or not "torturing" the hardware. NvRTX is also equipped with support for other Nvidia technologies, such as RTX Mega Geometry to display geometric objects with the help of ray tracing. Then there is DLSS (Deep Learning Super Sampling) 4 so that AI can improve the quality of objects in the game, and Frame Generation to improve the quality of the frame rate with the help of AI. Back to Zorah, with the various technologies above, Nvidia claims that this game can display visual objects with super sharp details and lighting that resembles the real world.
