Unreal Engine Startup Optimization: The 38,000 Tooltip Secret

2025-09-06

Slow Unreal Engine startup times? A developer discovered the engine creates a whopping 38,000 tooltips, consuming significant resources and time. Most of these tooltips are never actually displayed. A simple code change delays tooltip creation until needed, dramatically improving startup speed without impacting runtime performance. This optimization shaved off 2-5 seconds of startup time in debug builds and reduced memory usage.

Unreal Engine's Multiplayer Overhead: A Memory Optimization Surprise

2025-04-08

An Unreal Engine developer, while using a memory layout visualizer, unexpectedly discovered that certain data structures added for multiplayer support in Unreal Engine are redundant in single-player games. These structures consume a significant amount of memory; for example, custom structs used for replicating component attachments and actor movement occupy 120 and 216 bytes respectively. By commenting out these unused variables and related code in single-player mode, a memory saving of approximately 392 bytes per actor was achieved. While not significant for most projects, this optimization could yield considerable savings (potentially up to 100MB) for projects with a high number of actors (e.g., over 100,000).
