At Unreal Fest in Orlando, Epic Games showcased new features for Unreal Engine 5 through a tech demo of CD Projekt Red's Witcher 4 and hosted training sessions for developers. Key topics included shader compilation stutters and performance issues in Unreal Engine games, with a focus on optimization methodologies rather than the engine itself. Insights revealed persistent performance optimization challenges, particularly with shader compilation and traversal stutters. Developers were encouraged to implement PSO precaching in Unreal Engine 5.2 or newer, although neither solution is perfect. Obsidian's game Avowed began development in Unreal Engine 4 before transitioning to version 5.3.2, while aiming for specific frame rates on Xbox Series S and X. The team size for Avowed was 140, with only 15 in technical roles, which may have limited their ability to fully utilize new features. Unreal Engine 5.6 offers performance enhancements that require strategic implementation by developers. Attendance at Epic's sessions was high, indicating a growing awareness of performance issues among developers. The hope is that future titles will leverage the latest engine version to address these challenges effectively.
