Speeding Up Game Logic in Unreal Engine - Unreal Fest Online 2020

Explore an advanced approach to optimizing game logic performance in large-scale multiplayer titles using Unreal Engine. Learn how to increase data and instruction cache coherency and implement automatic parallelization to maximize thread occupancy. Dive into Entity Component System (ECS) concepts and discover Funcom's implementation of a scheduler that extends the taskgraph for efficient dispatching and batch processing of game logic on component sets. Gain insights into techniques such as tick task aggregation, property energization, and garbage collection optimization. Examine practical examples including healer components, damage alerts, and threat safety mechanisms. Understand the integration with Blueprints and replication systems. Ideal for engine and game programmers tackling performance bottlenecks in the game thread, especially for server-side and performance-limited platforms.
