Unreal Engine Game Optimization on a Budget
summary
Practical checklist for immediate wins: run Unreal Insights with trace channels and bookmarks to find whether the bottleneck is game thread, render thread, or GPU; run memreport -full and obj list class to find unexpected 100–200+ MB body setups; use DumpTicks grouped and stat vobjects to stop needless ticking; enable Significance Manager to reduce tick/update rates by distance; use Oodle compression and Animation Compression Library (reported ~50x faster compress, much smaller runtime memory) and distance/occlusion culling to cut draw and shadow cost.
