When CD Projekt Red unveiled The Witcher 4 tech demo at Unreal Fest, the reaction was immediate. A glimpse of the future of The Witcher, a peak behind the curtain at a new partnership and the launch of Unreal Engine 5.

The demo was built using Unreal Engine 5.6, and shows new protagonist Ciri exploring some forested lands and a marketplace known as Valdrest. Epic says the demo is designed in part to show off how the latest iteration can handle both bustling scenes and foliage in an open-world setting.
