We also reveal the never-before-seen region of Kovir, a rugged land where cities are built on trade and keep a careful distance from the military conflicts that plague the rest of the north.<\/p>\n<p class=\"\">But the focus of this tech demo is just that \u2014 tech \u2014 and we were proud to show it live on stage, running at 60 frames per second on a PlayStation 5. The tools highlighted won\u2019t just power The Witcher 4, but will also be shared with the wider video game development community through Unreal Engine 5. The tech we\u2019re creating with Epic will benefit the entire industry, ultimately bringing a better experience to players.<\/p>\n<div class=\"shortcode shortcode--youtube\">\n<div class=\"youtube-video\" data-youtube-id=\"lOAiB3GZOQo\" data-title=\"\">\n\t<button class=\"youtube-video__load-button\"><br \/>\n\t\t\t<svg class=\"icon icon--play icon--26 icon--play icon--blue\" aria-hidden=\"true\" viewbox=\"0 0 20 20\" focusable=\"false\" version=\"1.1\">\n\t\t<title><\/title><path fill-rule=\"evenodd\" class=\"icon-primary-color\" d=\"M0 1.75v17l20-8.5z\"><\/path>\t<\/svg><br \/>\n\t\t\t\t\t<span class=\"screen-reader-text\">Play  Video<\/span><br \/>\n\t<\/button><\/p>\n<div class=\"youtube-video__iframe\"><\/div>\n<\/div><\/div>\n<h2 class=\"wp-block-heading\">ML Deformer<\/h2>\n<p class=\"\">Early in the tech demo we introduce Ciri\u2019s horse Kelpie to the world \u2014 and how she\u2019s far more complex than our old friend Roach. Alongside tech that makes controlling Kelpie feel much more grounded and lifelike, we\u2019ve worked hard to develop high-quality, real-time character deformations.<\/p>\n<p class=\"\">ML Deformer allows elements like Kelpie\u2019s muscles to move and flex accurately, thanks to high-fidelity data providing it with the ability to approximate complex deformations efficiently during gameplay. This allows these incredibly realistic movements to take place without the game taking a performance hit.<\/p>\n<p><a href=\"https:\/\/live.staticflickr.com\/65535\/54563969559_d193328a53_4k.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/live.staticflickr.com\/65535\/54563969559_d193328a53_4k.jpg\" alt=\"\"><\/a><\/p>\n<h2 class=\"wp-block-heading\">Fast Geometry Streaming<\/h2>\n<p class=\"\">We\u2019re paying attention to the large scale too. Fast Geometry Streaming allows everything in the tech demo \u2014 from the snowy mountaintops to the deep valleys and vast forests \u2014 to seamlessly load without compromising performance. It\u2019s present throughout the tech demo, and the fact it can\u2019t be noticed proves it\u2019s doing its job.<\/p>\n<p class=\"\">Consider when we catch up with Ciri before she reaches the bustling trading hub of Valdrest, for example. We move quickly through the world, in and around different elements of the environment, but there\u2019s no stuttering or object pop-ins. Fast Geometry Streaming is optimized to quickly load static geometry, using a lightweight method to register and unregister assets. The result is what we show throughout the tech demo: smooth and seamless world loading that allows the beauty of Kovir to shine.<\/p>\n<p><a href=\"https:\/\/live.staticflickr.com\/65535\/54564020643_5c9460f6cc_4k.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/live.staticflickr.com\/65535\/54564020643_5c9460f6cc_4k.jpg\" alt=\"\"><\/a><\/p>\n<h2 class=\"wp-block-heading\">Nanite Foliage<\/h2>\n<p class=\"\">Speaking of Kovir, we take a detour through one of its dense forests while Ciri is riding to Valdrest. Nanite Foliage technology we\u2019re developing with Epic, and how it allows our developers\u2019 artistic vision to be fully realised in Unreal Engine 5. This tech renders incredibly detailed and realistic trees and vegetation in terms of both density and fidelity, without compromising performance.<\/p>\n<p class=\"\">Nanite Foliage is a new technology that efficiently renders vast amounts of foliage at runtime, making it possible to effortlessly populate landscapes with complex assets \u2014 such as lush trees with individual branches that sway in the wind.<\/p>\n<p><a href=\"https:\/\/live.staticflickr.com\/65535\/54564117780_047a0daa43_4k.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/live.staticflickr.com\/65535\/54564117780_047a0daa43_4k.jpg\" alt=\"\"><\/a><\/p>\n<h2 class=\"wp-block-heading\">Unreal Animation Framework<\/h2>\n<p class=\"\">We always want to make our open worlds feel alive and lived in, and the Unreal Animation Framework shown off in the tech demo lets us add more life than ever to the villages, towns, and cities of the Continent. This tech powers advanced blending, state machines, and procedural animation workflows, letting us have many complex characters interacting with the world at once.<\/p>\n<p class=\"\">When we place a band on the stage in Valdrest, for example, we utilize Unreal Animation Framework to drastically increase the number of NPCs on screen. And these aren\u2019t just simple onlookers standing still or operating on a loop; each one reacts to what\u2019s going on around them. We want the gap between Ciri and the NPCs of The Witcher 4 to be as small as possible.<\/p>\n<p><a href=\"https:\/\/live.staticflickr.com\/65535\/54563788121_cc1f763b5c_4k.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/live.staticflickr.com\/65535\/54563788121_cc1f763b5c_4k.jpg\" alt=\"\"><\/a><\/p>\n<h2 class=\"wp-block-heading\">Mass Framework<\/h2>\n<p class=\"\">Another tool that adds to the believability and lived-in feeling of the world, Mass Framework simulates large crowds and AI behaviour like the ones seen in the busy market of Valdrest. The data-driven design of Mass manages thousands of agents with minimal performance cost, making it ideal for creating realistic, dynamic populations in games.<\/p>\n<p class=\"\">It also allows smart objects and complex interactions to function. As Ciri approaches the market we see her bump into a man carrying a crate of apples, for example. Notice how he doesn\u2019t just react to her collision; he loses his footing and drops several apples, which roll down the hill and trigger further, unscripted chain reactions like children running to steal one or pigs looking for an early lunch. Implementing interactions like these is one way we\u2019re making The Witcher 4 the most immersive Witcher game to date.<\/p>\n<\/div>\n<p><a href=\"https:\/\/blog.playstation.com\/2025\/06\/03\/the-witcher-4-unreal-engine-5-tech-demo-on-ps5-revealed\/\">Go to Source (PlayStation.com)<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We at CD Projekt Red are collaborating with Epic Games to push open-world game design further than ever before, and we wanted to share our progress with the gaming community through The Witcher 4 Unreal Engine 5 Tech Demo \u2014 a showcase of how we\u2019re bringing more life, depth, and reactivity to the Continent than<\/p>\n","protected":false},"author":4,"featured_media":64270,"comment_status":"registered_only","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[6097,2919,1041,1489,43,169,930,15,2119,6688,222],"class_list":["post-64269","post","type-post","status-publish","format-standard","has-post-thumbnail","category-playstation","tag-collaborating","tag-design","tag-epic","tag-further","tag-game","tag-games","tag-openworld","tag-playstation","tag-projekt","tag-push","tag-than"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>The Witcher 4 Unreal Engine 5 Tech Demo on PS5 revealed | Xtreme Servers<\/title>\n<meta name=\"description\" content=\"View The Witcher 4 Unreal Engine 5 Tech Demo on PS5 revealed for free, here on XtremeServers.
