Witcher 4 Struggles in Development, Unreal Engine Blamed

Daniel Vavra, creator of the Kingdom Come trilogy and Warhorse Studio co-founder, criticizes Unreal Engine's limitations in handling complex, open-world environments. He claims this engine's shortcomings are the root cause of The Witcher 4's troubled development.

Vavra highlights Unreal Engine's struggles with vegetation, stating, "Unreal works well for deserts and rocks, but the engine couldn't handle trees for a long time." He points out the limitations of Nanite technology in rendering realistic foliage.

A CD Projekt employee, reportedly speaking with Vavra, confirmed difficulties adapting scenes that functioned perfectly on the RED Engine to Unreal Engine. These challenges are allegedly causing significant production delays.

Vavra questions CD Projekt's decision to switch to Unreal Engine, given their existing, robust RED Engine, noting that most open-world games utilize custom engines.

He also points out the high system requirements of Unreal Engine, requiring expensive hardware beyond the reach of many players, despite its ability to generate stunning visuals.

Despite the years since the first Kingdom Come: Deliverance, anticipation remains high for its sequel. Launching February 4th, Kingdom Come: Deliverance 2 promises enhanced graphics, refined combat, and a historically-grounded narrative continuing Indřich's journey.
