The Witcher 4 will support Path Tracing and RTX Mega Geometry for maximum world detail

CD Projekt RED has confirmed that The Witcher 4 will support Path Tracing on PC, and the game will also take advantage of Nvidia's RTX Mega Geometry technology.

Cezary Bella, rendering engineer at CDPR, said in Nvidia's latest video:

"We are collaborating with both Epic Games and NVIDIA to streamline the implementation of Path Tracing into The Witcher 4."

This marks the first official confirmation of Path Tracing coming to the game. Nvidia didn't include The Witcher 4 in its Path Tracing-supported titles list in its most recent blog post – the game was instead mentioned in a separate entry dedicated to RTX Mega Geometry.

RTX Mega Geometry is designed to handle massive scenes and can update geometry up to 100 times faster than previous methods. According to Nvidia, the technology enables full-fidelity path tracing with advanced detail and real-time tessellation.

The latest version of RTX Mega Geometry introduces a reworked level-of-detail system for foliage. It selectively updates scenes, cuts memory usage, and boosts performance without any visible drop in image quality. For the first time, developers can apply path tracing to dense natural environments featuring millions of detailed plants and trees, unique animation, and accurate real-time lighting and shadows.

The Witcher 4 runs on the latest version of Unreal Engine 5, with support for both Lumen and Nanite. CD Projekt RED has promised the game will perform noticeably better than many other UE5 titles.

A release date for The Witcher 4 hasn't been announced yet, but CD Projekt RED will showcase the game in June at the Unreal Engine Fest event.
