Maximizing Your Game's Performance in Unreal Engine
summary
Uses Unreal Engine 5 profiling tools to find and fix real bugs: launches Unreal Insights and uses stat unit and profile GPU captures, finds editor at 30→60 FPS by shrinking point light attenuation and disabling cast shadows, fixes a 2–3 second hitch caused by synchronous LoadObject by switching to async/streamable handles, reduces a 135 ms fog cost by replacing computational noise and huge card sprites with texture samples and higher alpha, and closes a 21 MB leak caused by incorrectly using new plus pointer copies.
