The highly anticipated next installment in the Witcher series, currently known as The Witcher 4, is set to leverage cutting-edge RTX Mega Geometry technology, according to recent announcements. This marks a significant shift for CD Projekt Red, who are developing the game using Unreal Engine 5, a departure from their in-house REDengine. The collaboration with Epic Games, the creators of Unreal Engine, aims to deliver a visually stunning and expansive open world experience, and RTX Mega Geometry is poised to play a crucial role in achieving that ambition.
The move to Unreal Engine 5 was first announced in 2022, signaling CD Projekt Red’s intent to streamline development and potentially turn into a multi-production studio. As Charles Tremblay, VP of technology at CD Projekt Red, explained in an interview with Digital Foundry, the decision wasn’t a criticism of their previous engine, but rather a strategic choice to better position the company for future projects. “I don’t seek people to think the tech we had was problematic – we’re super proud of what we achieved with Cyberpunk,” Tremblay stated. “when we started the new Witcher project, we wanted to be more of a multi-production company, and our technology was not well made for that.”
Unreal Engine 5 and the Promise of a Vast Open World
The partnership between CD Projekt Red and Epic Games has been focused on enhancing Unreal Engine 5’s capabilities, particularly in the realm of open-world development. The tech demo showcased at Unreal Fest Orlando in June 2025 offered a glimpse into the potential of this collaboration. The demo, set in the previously unseen region of Kovir, featured protagonist Ciri and her horse, Kelpie, traversing rugged mountains, dense forests, and the bustling port town of Valdrest. This region, Kovir, will be entirely new to players of the video game series, marking a significant expansion of the Witcher universe.
The demonstration highlighted several innovative features within Unreal Engine 5, designed to drive performance, visual fidelity, and create a truly immersive open world. A key component of this visual enhancement is Nvidia’s RTX Mega Geometry, a technology that addresses the challenges of rendering scenes with incredibly detailed geometry, particularly when utilizing ray tracing. This technology was previously demonstrated in the game Alan Wake 2, showcasing its ability to handle complex visual elements.
RTX Mega Geometry: A Deep Dive into the Technology
RTX Mega Geometry is designed to overcome limitations in traditional rendering methods when dealing with highly detailed scenes. Specifically, it excels in scenarios like rendering dense foliage or intricate natural environments. The system accelerates the process of creating Bounding Volume Hierarchies (BVH), which are essential for efficient ray tracing. By streamlining BVH creation, RTX Mega Geometry allows for significantly improved performance in complex scenes, enabling the rendering of up to 100 times more ray-traced triangles within a single scene. This translates to a richer, more detailed, and visually realistic gaming experience.
According to the Digital Foundry interview with CD Projekt Red, the tech demo ran at 60 frames per second on a base PlayStation 5, demonstrating the potential for high-fidelity graphics on current-generation consoles. This is particularly impressive given the ambition of the project and the complexity of the environments showcased. The team at CD Projekt Red and Epic Games worked closely to optimize the technology and ensure a smooth and visually compelling experience.
Kovir: A New Frontier in the Witcher Universe
The choice of Kovir as the setting for the tech demo is significant. This region, previously only mentioned in the Witcher novels, represents a new and unexplored territory within the franchise. Kovir is known for its diverse landscapes and unique cultural influences, offering a fresh backdrop for the next chapter in Geralt’s—and now Ciri’s—story. The demo provided a tantalizing glimpse of the region’s potential, showcasing its rugged beauty and the intricate details of its towns, and settlements.
The development team emphasized their commitment to creating a truly immersive and believable world. This includes not only the visual fidelity of the environments but as well the attention to detail in the character models, animations, and overall atmosphere. The use of Unreal Engine 5 and RTX Mega Geometry is intended to elevate the Witcher experience to new heights, offering players a level of visual immersion previously unseen in the series.
The Development Timeline and Anticipated Release
Whereas an official release date for The Witcher 4 remains unconfirmed, industry speculation suggests a potential launch in 2028. This timeline reflects the complexity of the project and the ambitious scope of the game. The development team is taking a deliberate approach, prioritizing quality and polish over a rushed release. The extended development cycle also allows for continued refinement of the technology and the incorporation of player feedback.
The transition to Unreal Engine 5 has presented both challenges and opportunities for CD Projekt Red. While the new engine offers significant advantages in terms of visual fidelity and open-world development, it also requires a substantial investment in learning and adaptation. The close collaboration with Epic Games has been instrumental in navigating this transition and ensuring a smooth development process.
Looking Ahead: The Future of The Witcher Franchise
The integration of RTX Mega Geometry into The Witcher 4 represents a significant step forward in gaming technology. It demonstrates the potential for ray tracing to deliver truly photorealistic visuals and immersive experiences. As hardware continues to evolve, People can expect to see even more advanced rendering techniques emerge, further blurring the lines between virtual and real worlds.
The success of The Witcher 3: Wild Hunt has set a high bar for the next installment in the series. Players are eagerly anticipating a return to the Continent, and the promise of a vast, visually stunning open world powered by Unreal Engine 5 and RTX Mega Geometry is generating considerable excitement. The development team is committed to delivering an experience that lives up to the expectations of fans and pushes the boundaries of what’s possible in gaming.
CD Projekt Red continues to share updates on the game’s development through official channels. Players can stay informed about the latest news and progress by following the company’s website and social media accounts. The anticipation for The Witcher 4 is building, and the gaming community is eagerly awaiting the opportunity to explore the new world of Kovir and embark on a new adventure with Ciri.
The next major update from CD Projekt Red is expected during a planned showcase in late 2026, where they intend to reveal more details about the game’s story, characters, and gameplay mechanics. Until then, fans can continue to speculate and anticipate the arrival of this highly anticipated title. We will continue to monitor developments and provide updates as they become available.
