Challenges Faced with Unreal Engine 5 in The Witcher 4 Development

The anticipation for The Witcher 4 has fans excited. However, the journey of its development has not been smooth. The game faces several hurdles, with many developers raising concerns about the Witcher 4 Unreal Engine 5 Issues. This article explores these challenges and their implications for the game’s development.

Witcher 4 Unreal Engine 5 Issues

Daniel Vávra and others have expressed concerns over using Unreal Engine 5 for The Witcher 4. Vávra mentioned that a colleague at CD Projekt RED indicated the game is stuck in «development hell,» a complex situation that can lead to significant delays and problems. For more details, see this source.

Need for Optimization

One primary issue discussed by Vávra is the optimization of UE5. He pointed out that this engine struggles to handle complex open worlds. Generating vegetation is particularly challenging, as the Nanite technology does not effectively process trees or other detailed objects.

Challenges with Nanite

Nanite is designed to provide high-quality graphics without sacrificing performance. However, its limitations have raised doubts. Developers need a reliable method to create rich environments without impacting frame rates. Unfortunately, UE5’s current state falls short.

Comparison with RED Engine

In the discussion of game engines, a significant comparison arises between UE5 and the previously used RED Engine. Vávra critically evaluates the decision to abandon RED Engine, believing it was more suitable for The Witcher series, given its successful use in games like Cyberpunk 2077 and The Witcher 3.

Advantages of RED Engine

RED Engine provided a tailored experience for both developers and players, offering better optimization and integration of game features. With its departure, concerns grow over UE5’s ability to deliver a similar experience, sparking debates among gamers and developers alike.

Technical Challenges

Another major point of contention is the technical challenges associated with UE5. Optimizing this engine for various computer configurations is crucial. Vávra mentioned that achieving peak performance often requires high-end hardware. For a perspective on how engine competitions unfold, check this article.

Performance Requirements

Many players do not own high-performance computers, raising concerns about accessibility. Players with standard setups might face performance drops or lag, potentially detracting from the overall gaming experience.

Loss of Specialists

The transition from RED Engine to UE5 also brought about another key issue: the loss of technical specialists. After personnel changes at CD Projekt RED, the remaining staff had to deal with training new employees. This transition proved to be costly in time and resources.

Impact on Development

This insufficient workforce has ramifications for The Witcher 4’s timeline. A limited number of specialists skilled in UE5 could contribute to delays. The need for quick adaptation to new tools can impede the game’s progress, raising concerns about the quality of the final product.
