PS5 super-fast loading led Epic to rewrite parts of Unreal Engine 5

"The PlayStation 5 provides a huge leap in both computing and graphics performance, but its storage architecture is also truly special," Penwarden said. "The ability to stream in content at extreme speeds enables developers to create denser and more detailed environments, changing how we think about streaming content. It's so impactful that we've rewritten our core I/O subsystems for Unreal Engine with the PlayStation 5 in mind."
