- Unreal Engine has evolved into a versatile 'everything machine' beyond just a game engine.
- Editor startup times are a significant drawback due to the engine's multitude of features.
- Epic has implemented solutions like live-coding and derived data caches to mitigate startup delays.
- A major inefficiency was found in the tooltip system, where 38,000 tooltips were created at startup, consuming significant resources.
- Optimizing tooltip creation to be on-demand rather than at startup can save time and memory without impacting runtime performance.
- Optional sources like project settings and editor preferences contribute heavily to the number of tooltips created.
- Removing unused tools and panels from the editor layout can further optimize startup times.
