Unreal Engine 5 Gets Stunning Demo With Incredible Graphics, Enters Early Access Epic shows off Unreal Engine 5 in even more depth and detail. It's a big day for Epic's Unreal Engine, as the Fortnite studio announced on Wednesday that Unreal Engine 5 is now available in early access for game developers ahead of its public release in early 2022. Not only that, but Epic also released a stunning new tech demo showing off the new engine and its capabilities, and it's very, very impressive. The Valley of the Ancient tech demo shows off new features like Nanite and Lumen that promise to provide a "generational leap" in visual fidelity. The video also covers some of the new systems for developers, such as World Partition, which breaks big game worlds down into chunks so developers can streamline their processes and work more efficiently. Additionally, Unreal Engine 5 now has Quixel built in, so developers can more quickly and easily incorporate photorealistic items and objects into games.
