⚡ Performance Fundamentals

What/Why: Avoid the usual traps in BP-heavy projects and keep frames stable.

Prereqs

• Profiling tools: Stat Unit, Stat GPU, Insights

Steps

1. Eliminate tick

• Replace with timers, events, latent nodes; centralize updates

2. Async everything heavy

• Soft refs + async load; prefetch in transitions

3. Pool and reuse

• Object pools for projectiles/FX; avoid spawn/destroy churn

4. LOD and HLOD

• Use Nanite settings and HLOD for large worlds; VT for heavy materials

Data

• Keep heavy refs out of always-loaded assets

Testing

• Capture budgets; set gates for ms/frame and memory; regress regularly

Suggested prompts

• “Replace a tick-based loop with timers and events; show before/after.”
• “Set up a basic object pool in a component.”
• “Checklist to find hidden tick costs in a Blueprint.”

Prompts for this example

• “Provide a timer-driven interaction scan at 10 Hz that replaces Tick.”
