The Witcher 4 is in production hell because of the Unreal Engine

Daniel Vavra, the creator behind the Kingdom Come trilogy and a co-founder of Warhorse Studios, has expressed strong criticism towards the Unreal Engine, claiming it struggles with the demands of creating intricate and expansive open worlds. According to Vavra, this limitation is a significant factor contributing to the production challenges faced by The Witcher 4. He argues, "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." He further criticizes the engine's Nanite technology, stating it's inadequate for rendering vegetation effectively.

A CD Projekt employee reportedly shared with Vavra that scenes which functioned perfectly on the RED Engine were problematic on Unreal, leading to significant delays in development. Vavra finds it perplexing that CD Projekt chose to switch from their successful RED Engine to Unreal for open-world game development, as custom engines are typically preferred in such cases.

While acknowledging Unreal Engine's capability to produce stunning visuals, Vavra points out its high system requirements, noting that it demands computers costing several thousand euros, which are beyond the reach of most gamers.

Despite years passing since the release of the first Kingdom Come: Deliverance, the fascination with its medieval Bohemian setting remains strong.
