In March, CDPR announced the new "The Witcher" game (not called "The Witcher 4") and said that it would switch to Unreal Engine 5 development. Bart Wronski, a former employee of CDPR, explained on Twitter why: Every time a new game was developed, he had to rewrite the RedEngine engine, but it would waste a lot of time, and the staff would have to work a lot of overtime, which was very difficult to maintain. To avoid this happening later, CDPR chose Unreal Engine 5, which has a solid foundation.
At last night's Unreal Engine 5 live event, CDPR Game Director Jason Slama also explained why the new "The Witcher" game switched to Unreal 5, which confirmed Bart Wronski's statement. Jason Slama said Epic's Unreal Engine is more stable, and at least one code change won't affect the remaining 1600 places.
"One thing to keep in mind when talking about the contrast between open-world games and linear games is that there are more situations that can go wrong or have to be paid attention to," he says. Players are free to choose the direction of their advance, not bound by the rules of the game, and theoretically they can play in any order. If this is to be truly achieved, it means that a very stable environment is needed. ”
