Daniel Vavra, creator of the Kingdom Come trilogy and Warhorse Studio co-founder, criticizes Unreal Engine's limitations for complex open-world games, suggesting it contributed to The Witcher 4's troubled development. He claims Unreal struggles with intricate environments, particularly vegetation, stating, "Unreal works well for deserts and rocks, but the engine couldn't handle trees for a long time." Vavra highlights the inadequacy of Unreal's Nanite technology for realistic vegetation rendering.

A CD Projekt employee reportedly confirmed to Vavra that scenes previously running smoothly on RED Engine now cause significant production issues in The Witcher 4's Unreal Engine development. Vavra questions CD Projekt's decision to switch engines, noting that most open-world developers utilize proprietary engines.

Vavra also points out Unreal Engine's high system requirements, demanding expensive hardware inaccessible to many players, despite its impressive visual capabilities.

Meanwhile, anticipation builds for the February 4th release of Kingdom Come: Deliverance 2, continuing Indřich's story with improved graphics, combat, and a historically-grounded narrative. This post will provide updates on system requirements and estimated playtime, along with download instructions upon release, ensuring you're among the first to experience the enhanced medieval setting.
