'Witcher 4' tech demo shows unreal engine 5's latest features
CD Projekt Red and Epic Games have unveiled a new technology demonstration for The Witcher 4, offering an early look at the game's graphical fidelity and open-world design powered by Unreal Engine 5.
Presented during the State of Unreal keynote at Unreal Fest 2025 in Orlando, the demo follows protagonist Ciri and her horse Kelpie exploring the newly introduced region of Kovir, a location not previously seen in the Witcher series. Below is the full video of the event.
Although not actual gameplay footage, the tech demo highlights several advanced Unreal Engine technologies designed to elevate realism and performance.
Nanite foliage technology renders individual leaves and branches on trees with dynamic wind effects, while chaos physics simulates natural movements of cloth and muscle, exemplified by Ciri's cape and Kelpie's musculature. Character motion matching ensures fluid interaction between Ciri and Kelpie, showing realistic weight shifts and movement synchronization.

The Witcher 4: Geralt's voice actor shuts down ‘woke' claims over Ciri being lead
Doug Cockle, the voice actor for Geralt of Rivia, has defended the decision to make Ciri the lead character in The Witcher 4, responding to criticism that the move is 'woke' by urging sceptics to read the original novels. Speaking in a recent interview, Cockle said it was natural for the franchise to focus on a different protagonist after Geralt's story had reached its conclusion. 'You can't just have Geralt for every single game for The Witcher ad nauseam through eternity,' he said. 'It's a cool character from the Witcher, and they're going to focus on that character.' The Witcher 4 was officially announced at the 2024 Game Awards, revealing that Ciri would star in the upcoming game. Cockle said the previous expansion, Blood and Wine, was intended to wrap up Geralt's journey. 'We've seen the end of Geralt's journey,' he said. 'Celebrate Ciri, I celebrate her being the protagonist.' Some fans have criticised the choice, describing it as a 'woke' decision. Cockle rejected this, stating: 'If you think it's woke, read the damn books — they're good, first of all. And secondly, you won't think it's so woke anymore.' The Witcher games are based on a series of novels by Polish author Andrzej Sapkowski, which increasingly centre on Ciri's character. Cockle noted that the games had not yet fully explored her story, which the new game now plans to address. 'There's a whole rich world of stuff to explore with Ciri that they didn't do when they put her into Witcher 3, because the story was about Geralt. But she hints at it,' he said. Cockle also compared the transition to other popular franchises that have moved on from their original leads. 'Uncharted put Nathan Drake into retirement so we could focus on Chloe and Nadine in The Lost Legacy, and they were a breath of fresh air,' he said. No release date has yet been announced for The Witcher 4. In the meantime, fans are encouraged to revisit The Witcher 3 or explore similar role-playing games.

Cyberattack to cost UK retailer Marks & Spencer £300mn
LONDON: British clothes-to-food retailer Marks and Spencer on Wednesday said a cyberattack affecting its online service is set to last through to July and cost the group £300 million ($404 million). Marks last week revealed that some personal data of its customers had been stolen in a cyberattack that has crippled its online services for weeks. 'In Fashion, Home & Beauty, online sales and trading profit have been heavily impacted by the necessary decision to pause online shopping, however stores have remained resilient,' Marks said in a statement. 'We expect online disruption to continue throughout June and into July as we restart, then ramp up operations.' The impact on annual group operating profit is estimated at 'around £300 million… which will be reduced through management of costs, insurance and other trading actions', the retailer added. Epic Games' Fortnite returns to Apple App Store in US after nearly 5 years The news came as Marks on Wednesday reported operating profit before adjusting items of £985 million for its financial year to the end of March. Following the update, its share price dropped 2.5 percent at the start of trading in London. Group operations have since Easter been hampered by a ransomware sting which forced the retailer to suspend online sales, contactless payments instore and even recruiting operations. Marks said information stolen could include names, dates of birth, home addresses and telephone number. However, it did not include 'useable payment or card details', nor account passwords. The company reported the incident to relevant government authorities and law enforcement. A wave of cyberattacks have hit British retailers in recent weeks, including luxury department store Harrods and the Co-op food chain.
