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 is a significant factor contributing to the reported production challenges faced by The Witcher 4.

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

A CD Projekt employee, reportedly speaking to Vávra, described extensive difficulties adapting scenes that ran smoothly on REDengine to Unreal Engine, further fueling claims of significant production hurdles.

Vávra questions CD Projekt's decision to switch to Unreal Engine, given their established and apparently well-suited REDengine, noting that most open-world developers utilize proprietary engines.

He also highlights the high system requirements of Unreal Engine, demanding costly hardware beyond the reach of many players, despite its capacity for stunning visuals.

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

This post summarizes the latest details surrounding the upcoming release, including system requirements and estimated playtime. We will also provide download instructions upon release, ensuring you can experience the medieval atmosphere firsthand.
