"Witcher 4 Faces Delays Due to Unreal Engine Issues"

Daniel Vavra, the creator of the Kingdom Come trilogy and one of the founders of Warhorse Studio, has expressed strong criticism towards Unreal Engine, claiming it struggles with the demands of creating an intricate and open world. According to Vavra, this limitation has significantly impacted the development of The Witcher 4, plunging it into what he describes as "production hell."

"Unreal works well if you want to make a game with desert and rocks, but the engine couldn't handle trees for a long time," Vavra remarked. He further criticized the engine's Nanite technology, stating it is inadequate for rendering vegetation effectively. A CD Projekt employee reportedly confirmed to Vavra that scenes which ran smoothly on the RED Engine were causing significant issues when ported to Unreal Engine.

Vavra questions the decision by CD Projekt to switch from their own RED Engine, which he considers robust, to Unreal Engine for open-world games. He points out that most studios developing open-world games opt to use custom engines tailored to their specific needs. Additionally, Vavra highlighted that while Unreal Engine can produce stunning visuals, it demands high-end computers that are prohibitively expensive for most gamers.

Despite the years since the release of the first Kingdom Come: Deliverance, interest in its medieval Bohemian setting remains high. Fans are eagerly awaiting the sequel, set to launch on February 4, which promises to continue Indřich's adventures with upgraded graphics, a refined combat system, and a narrative deeply rooted in historical events.
