CDPR officially announced yesterday that a new Game of The Witcher is in development, and mentioned that it will be produced with Unreal Engine 5 instead of its own RedEngine game engine. Bart Wronski, a former EMPLOYEE at 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 employees 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.
In another tweet, Bart Wronksi further elaborated on what he meant by rewriting the engine, confirming that many core-level systems were rewritten in The Witcher 2 and The Witcher 3, as well as cyberpunk 2077.
"The core of our internal RedEngine 2.0 transformation is a greater focus on technology, and our partnership with Epic Games is based on that principle, which we and Epic both see as a long-term, satisfactory technology partnership." For CD Projekt Red, it's important to decide the technical direction of the next game from an early stage! ”
"In the past, we've spent a lot of resources and effort improving and adapting RedEngine to every game that comes after that. This collaboration is very exciting because it will improve the predictability and efficiency of development while giving us access to cutting-edge game development tools. I can't wait to make a bigger game with Unreal Engine 5! ”
