During today’s State of Unreal from Epic Games, CD Projekt Red shared new information on how they’re utilizing Unreal Engine 5 for development of The Witcher 4.
Since the strategic partnership was announced in 2022, CDPR has been working with Epic Games to develop new tools and enhance existing features in Unreal Engine 5 to expand the engine’s open-world development capabilities and establish robust tools geared toward CD PROJEKT RED’s open-world design philosophies. The demo, which runs on a PlayStation 5 at 60 frames per second, shows off in-engine capabilities set in the world of The Witcher 4, including the new Unreal Animation Framework, Nanite Foliage rendering, MetaHuman technology with Mass AI crowd scaling, and more. The tools showcased are being developed, tested, and eventually released to all UE developers, starting with today’s Unreal Engine 5.6 release. This will help other studios create believable and immersive open-world environments that deliver performance at 60 FPS without compromising on quality — even at vast scales. While the presentation was running on a PlayStation console, the features and technology will be supported across all platforms the game will launch on.
The Unreal Animation Framework powers realistic character movements in busy scenes. FastGeo Streaming, developed in collaboration with Epic Games, allows environments to load quickly and smoothly. Nanite Foliage fills forests and fields with dense detail without sacrificing performance. The Mass system handles large, dynamic crowds with ease, while ML Deformer adds subtle, realistic touches to character animation — right down to muscle movement.
We started our partnership with Epic Games to push open-world game technology forward. To show this early look at the work we’ve been doing using Unreal Engine running at 60 FPS on PlayStation 5, is a significant milestone — and a testament of the great cooperation between our teams. But we’re far from finished. I look forward to seeing more advancements and inspiring technology from this partnership as development of The Witcher 4 on Unreal Engine 5 continues.
