"Witcher 4 Production Struggles with Unreal Engine"

Daniel Vavra, the visionary behind the Kingdom Come trilogy and a co-founder of Warhorse Studios, has openly criticized Unreal Engine for its limitations in creating complex, open-world environments. He attributes the challenging development process of The Witcher 4 to these limitations, claiming that Unreal Engine struggles with intricate settings like forests, stating, "Unreal works well here if you want to make a game with desert and rocks, but the engine couldn't handle trees for a long time." He further criticizes Unreal's Nanite technology, asserting it falls short in rendering vegetation effectively.

A CD Projekt employee reportedly told Vavra that scenes which ran smoothly on the RED Engine were causing significant delays on Unreal Engine, leading to what has been described as "production hell" for The Witcher 4. Vavra questions the decision of CD Projekt to switch from their successful RED Engine to Unreal, especially since custom engines are typically preferred for open-world games.

Moreover, Vavra points out that while Unreal Engine can deliver stunning graphics, it demands high-end computers that are beyond the reach of many gamers, saying, "The Unreal Engine can produce beautiful visuals, but it requires computers costing several thousand euros, which most players simply don't have."

Despite these industry insights, the excitement for the Kingdom Come series remains undiminished. The upcoming sequel, Kingdom Come: Deliverance 2, set to release on February 4, continues the saga of Indřich in medieval Bohemia. This eagerly awaited game promises enhanced graphics, an advanced combat system, and a narrative deeply rooted in historical events.

In anticipation of the release, we have gathered all the latest information, including system requirements and estimated playthrough times. We will also provide guidance on how to download Kingdom Come: Deliverance 2 immediately upon its release, ensuring you can immerse yourself in its medieval world without delay.
