"Witcher 4 Development Struggles with Unreal Engine"

Daniel Vavra, the visionary behind the Kingdom Come trilogy and a key figure at Warhorse Studios, has been vocal about his dissatisfaction with Unreal Engine, particularly in the context of developing intricate open-world games. Vavra asserts that Unreal Engine struggles with rendering complex environments, such as those filled with vegetation, which he claims the engine's Nanite technology is ill-equipped to handle. This, he believes, has contributed to the production challenges faced by The Witcher 4.

"Unreal Engine may excel in environments like deserts and rocky terrains, but it has historically struggled with rendering trees effectively," Vavra noted. He also mentioned conversations with a CD Projekt employee, who confirmed that scenes that ran smoothly on the RED Engine were problematic on Unreal. Vavra questions the decision of CD Projekt to switch from their well-regarded RED Engine to Unreal for an open-world game, pointing out that most studios in this genre develop their own engines.

Furthermore, Vavra criticized Unreal Engine for its high system requirements, stating that the engine demands computers that cost several thousand euros—far beyond the reach of most gamers.

Shifting focus to his own projects, Vavra's Kingdom Come: Deliverance, released several years ago, continues to captivate fans with its immersive medieval Bohemian setting. The much-anticipated sequel, Kingdom Come: Deliverance 2, is set to release on February 4. This sequel promises to enhance the original's experience with upgraded graphics, a refined combat system, and a narrative deeply rooted in historical events, continuing the adventures of Indřich.
