Optimizing animations in Unreal Engine 4
summary
Techniques for running about 1,000 simulated NPCs (≈200 visible) at 60 FPS in Full HD and 4K using Unreal Engine 4/5. Practical approaches include UE4/5 Significance Manager to scale updates, a grid/action‑point system and custom pathfinding to replace heavy behavior trees, multithreaded animation via AnimInstance proxy with data‑oriented memory layouts, and offloading work to the GPU with compute shaders plus DLSS/FSR upscaling. Measurements with the Editor profiler, RenderDoc and Unreal Insights show tick reductions of ~6–10%, multithreaded A* speedups of 3–6× and an example saving ~7 ms for 200 units.
