Building Night City: The Technology of 'Cyberpunk 2077'


Night City is one of the most ambitious virtual cities realized in a video game to date. Since it has a scale that, from the technical perspective, makes even The Witcher 3: The Wild Hunt seem small, the tech team at CD Projekt RED had to re-design many parts of their in-house engine. This talk describes the challenges faced and solutions developed when building Red Engine 4from using a prefab-based hierarchy to build and assemble the world, to the approaches taken for streaming different game systems, as well as how the team managed memory and CPU performance. In addition to covering the technical decisions that were made, this talk will dig into the "why" behind those decisions, as well as look at where the technology succeeded and what could be done differently.
