When talking about the Elder Scrolls 6, the topic is debatable. Looking at the game, it will be years away to be ready, but people working at it are doing a remarkable job. The question asked about whether or not Elder Scrolls 6 will have a new engine, is not so easy to answer. First, we have to understand how the game is working.
The Elder Scrolls 6
When talking about an engine, there is no single entity. It’s composed of modules (bits), units, and pipelines (rendering, physics, animation, data management). So when a game is developed, a lot of things are changed, replaced, or upgraded. That means that the engine isn’t going to change at once.
However, Todd Howard explained that confusion exists among the people who don’t make games. People see the engine as one thing, and the developers are viewing as a technology. Everything is working piece by piece, the rendering, the animation system, the scripting, the AI, the controls, and so on. When Howard is referring to piece by section, he’s saying that the Creation Engine that Bethesda is using for Elder Scrolls and Fallout is changing everything piece by piece.
Also, for Fallout 76, the company changed everything from the rendering to the new landscape system. To Starfield they’ve made even more changes and to the Elder Scrolls 6 even more. Talking about the Elder Scrolls 6, this is that kind of game that it’s staying a lot of years in pre-production. In full production is Starfield. In the Elder Scrolls 6, the developers are using photogrammetry for high-resolution photo scanning for places and people.
Finally, Bethesda is trying to solve all the problems with the bugs, and the company is using a new engine and new technologies for stopping them. The bugs are appearing due to the free roaming open world where hundreds of mission, people, and objects are encounter. Because of these combinations, something can work wrong.
