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-world games. He suggests this engine's shortcomings are a significant factor in The Witcher 4's reportedly troubled development.

Vávra contends that while Unreal Engine excels in rendering barren landscapes, its handling of vegetation, particularly trees, has historically been problematic, even with Nanite technology.

A CD Projekt employee, according to Vávra, described extensive difficulties adapting scenes that functioned perfectly in REDengine to Unreal Engine. These struggles, Vávra implies, are contributing to significant production challenges for The Witcher 4.

Vávra points out that most open-world games utilize proprietary engines, questioning CD Projekt's decision to switch to Unreal Engine, given the established capabilities of their REDengine.

While acknowledging Unreal Engine's visual prowess, Vávra highlights the substantial hardware requirements, necessitating expensive high-end PCs inaccessible to many players.

Despite its release several years ago, Kingdom Come: Deliverance continues to captivate players with its medieval Bohemian setting. The highly anticipated sequel, launching February 4th, promises to continue Indřich's adventures with improved graphics, refined combat, and a historically-grounded narrative.
