In a recent interview with VG247, Epic Games’ VP of engineering Nick Penwarden confirmed that they have rewritten some elements of UE5 with PS5 in mind :
” The PlayStation 5 provides a huge leap in both computing and graphics performance, but its storage architecture is also truly special. 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. “
PlayStation 5 launches this Holiday season worldwide. Unreal Engine 5 will be available mid 2021.
