"Witcher 4 Production Struggles with Unreal Engine"

Daniel Vavra, the creator of the Kingdom Come trilogy and a co-founder of Warhorse Studios, has been vocal about his dissatisfaction with Unreal Engine, criticizing its inability to handle the demands of a detailed and expansive open world. According to Vavra, this limitation has contributed to the tumultuous development of The Witcher 4, which he describes as being in "production hell."

"Unreal Engine might be suitable for creating games set in deserts and rocky terrains, but it struggled significantly with rendering trees for an extended period," Vavra stated. He further critiqued Unreal's Nanite technology, asserting that it falls short when it comes to generating realistic vegetation. This viewpoint was reportedly echoed by a CD Projekt employee, who mentioned that scenes which ran smoothly on the RED Engine were causing significant issues on Unreal.

Vavra expressed confusion over CD Projekt's decision to transition from their well-regarded RED Engine to Unreal Engine for their open-world projects. He pointed 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 deliver stunning graphics, it often requires high-end computers costing thousands of euros, a luxury many gamers cannot afford.

Turning to his own project, the first installment of Kingdom Come: Deliverance captivated players with its medieval Bohemian setting years ago, and the anticipation for its sequel remains high. Kingdom Come: Deliverance 2, set to release on February 4, promises to continue the adventures of Indřich with upgraded graphics, a refined combat system, and a narrative deeply rooted in historical events.
