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

Daniel Vávra, creator of the Kingdom Come trilogy and Warhorse Studios co-founder, has voiced strong criticism of Unreal Engine, claiming its limitations hinder the creation of complex, open worlds. He suggests this is a significant factor in the reported difficulties faced during The Witcher 4's development.

Vávra asserts that while Unreal Engine excels in rendering barren landscapes, its handling of vegetation, particularly trees, has historically been problematic, even with Nanite technology. He cites conversations with a CD Projekt Red employee who reportedly described extensive challenges adapting scenes that functioned perfectly within the REDengine to Unreal Engine. This, Vávra implies, is a major contributor to the game's troubled production.

Vávra points out the common practice of open-world developers utilizing proprietary engines, questioning CD Projekt Red's decision to switch to Unreal Engine given their established and successful REDengine. He further notes that Unreal Engine's visually impressive results often demand high-end PC hardware costing thousands of euros, potentially excluding a significant portion of players.

Despite the release of the original Kingdom Come: Deliverance several years ago, the medieval Bohemian setting continues to captivate players. The highly anticipated sequel, launching February 4th, will continue Indřich's story with enhanced visuals, refined combat, and a historically-grounded narrative.
