The Witcher 4 Confirms NVIDIA RTX Mega Geometry Ray Tracing Tech


CD PROJEKT RED has confirmed that the highly anticipated The Witcher 4 will incorporate NVIDIA’s cutting-edge RTX Mega Geometry technology, adding advanced ray tracing capabilities to the upcoming installment in the acclaimed RPG series. NVIDIA revealed that it has been working closely with the Polish developer since the early stages of the game’s development. While complete release details for The Witcher 4 remain unannounced, this technical partnership has already generated significant attention from the gaming community. The collaboration represents a major advancement in graphical technology for open-world gaming experiences.
RTX Mega Geometry is specifically designed for ray-traced scenes and can handle more complex geometric details than traditional pipelines. According to NVIDIA, the core principle involves adding full-quality Nanite virtualized geometry directly into the ray tracing bounding volume hierarchy (BVH). Essentially, this technology helps ray tracing scale more effectively with dense environments, complex meshes, and high-detail assets. The approach is particularly well-suited for expansive open-world games like The Witcher series, which typically feature intricate environments and detailed character models.

The Witcher 4 serves as CD PROJEKT RED’s next single-player open-world RPG, featuring Ciri leading a new chapter in the franchise. The game’s trailer was pre-rendered using a customized version of Unreal Engine 5 on NVIDIA GeForce RTX graphics cards, producing impressive visual results. Furthermore, The Witcher 4 has become a key component of Epic’s Unreal Engine 5.6 demonstration content, highlighting large open worlds, faster geometry data streaming, dense scenes, and ray tracing technology. This positions the game as a central focus for both companies’ research and promotional efforts.

NVIDIA and CD PROJEKT RED have partnered since the game’s development began, with The Witcher 4 set to launch featuring the latest RTX support technologies. CD PROJEKT RED has been collaborating with Epic to develop Unreal Engine functionality for large virtual worlds, while NVIDIA considers itself the initial partner for RTX technology aspects of the project. If implemented as planned, The Witcher 4 could become a benchmark for Unreal Engine 5 open-world games, combining technologies from both companies. Notably, RTX Mega Geometry technology has already been implemented in games like Alan Wake 2, which became the first title to support the feature in January of last year. This technical partnership suggests The Witcher 4 will push visual boundaries when it eventually releases.
