The session will attempt to familiarize participants with common bottlenecks that limit the scale and interactivity of games built with Unreal Engine—with brief explanations of high-level approaches commonly used to overcome those.
CD PROJEKT (CDPR) will explain the difficulty of introducing changes to the existing Gameplay Framework and will point to a small feature implemented by Epic in collaboration with CDPR and released with UE5.3 that will be commonly referred to during the talk as Decoupling.
