The Witcher 4 is in production hell because of the Unreal Engine

Daniel Vavra, creator of the Kingdom Come trilogy and Warhorse Studio co-founder, criticizes Unreal Engine's limitations for complex open-world games. He claims its inability to effectively handle intricate environments, particularly vegetation, is the source of The Witcher 4's reported development struggles.

"Unreal excels in desert and rock landscapes, but struggled with trees for a considerable time," Vavra stated, highlighting Nanite technology's shortcomings in rendering realistic vegetation. A CD Projekt employee reportedly confirmed to Vavra that scenes easily managed by RED Engine presented significant challenges in Unreal Engine, leading to extensive production difficulties.

Vavra points out that most open-world developers utilize proprietary engines, questioning CD Projekt's decision to switch to Unreal, given the capabilities of their existing RED Engine. While acknowledging Unreal Engine's visual prowess, he notes its high system requirements, making it inaccessible to many players.

Despite its age, Kingdom Come: Deliverance maintains considerable popularity. Its sequel, launching February 4th, promises enhanced graphics, refined combat, and a historically-grounded narrative continuing Indřich's journey.
