Maximizing Your Game's Performance in Unreal Engine
summary
Claims that every team member must measure impact and shows exact fixes using Unreal Insights and ProfileGPU. Demo finds a 3s hitch caused by a blocking load (Flush Async Loading) and replaces it with an async streamable handle, reducing stalls; a GPU hotspot reveals 135.96 ms spent in a particle material that had 300 oversized cards with noise (attenuation cut from 5000 to 100 and alpha/texture simplification restores 60 FPS); a leak traced to using `new` for a value-type in Tick is fixed by removing the heap allocation.
