CD Projekt Red is hard at work developing The Witcher 4, and it seems the company is learning from its past mistakes when it comes to technical performance.
The developer is now using Unreal Engine 5 to make The Witcher 4 instead of its bespoke RED Engine, and Charles Tremblay, vice president of technology at CD Projekt Red, tells Digital Foundry that since it had problems in the past going PC-first and then scaling down for console, "this time around we really want to be more console-first."
