The Witcher 4 demo at State of Unreal

CD Projekt Red showed a stunning tech demo at Unreal Fest Orlando 2025 of The Witcher 4 running on a base PlayStation 5 (PS5) with ray tracing enabled.



Read the official synopsis:

"This demo provides a glimpse at a number of 5.6’s powerful new open world features in action—all running on PlayStation 5 at 60 fps with raytracing—including the new, faster way to load open worlds via the Fast Geometry Streaming Plugin.

We get a peek at the power of 5.6 for handling busy scenes full of high-fidelity characters and visual effects like Chaos Cloth and an early look at Nanite Foliage, which provides a fast and memory-efficient way to achieve gorgeous foliage density and fidelity, slated for release in UE 5.7."

Remember that this isn’t gameplay of The Witcher 4 itself, but a deep dive into the technological groundwork.

Speaking on The Witcher 4 Unreal Engine 5 tech demo, Joint-CEO of CD Projekt Red, Michał Nowakowski, stated:

“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.”

I vividly remember playing Unreal Tournament on my iMac DV SE in 2000. The Unreal Engine has evolved, and The Witcher 4 promises truly next-gen fidelity.

Tim Sweeney, Founder and CEO of Epic Games, said:

“CD Projekt Red is one of the industry’s best open-world game studios, and we’re grateful that they’re working with us to push Unreal Engine forward with The Witcher 4. They are the perfect partner to help us develop new world-building features that we can share with all Unreal Engine developers.”

Sony's $250 million investment in Epic Games is paying dividends, and I can't wait to play The Witcher 4 on PS5.
