CD Projekt says abandoning in-house engine for The Witcher 4 had nothing to do with Cyberpunk 2077's technical woes

CD Projekt co-head Michał Nowakowski said the switch to Unreal Engine 5 for The Witcher 4 is not related to Cyberpunk 2077's technical problems. He said the company never aimed to develop its own technology and wants to tell stories; CD Projekt became the only studio outside Epic with access to the engine's internals.

• CD Projekt will replace REDengine with Unreal Engine 5 in The Witcher 4
• Nowakowski: Cyberpunk 2077 problems were not related to REDengine itself
• Studio gained access to Unreal Engine 5 internals
• Decision made after The Matrix Awakens demo on UE5
