Unreal Engine Startup Optimization: The 38,000 Tooltip Secret

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.
