Optimization Techniques in UDK/UE3
summary
Covers practical optimization techniques for UDK/UE3 games: prototype with the editor, UnrealScript and Kismet, move heavy math into C++, and preload assets to prevent runtime stalls. Shows how to profile with UDK stat commands, the game profiler and memory/shader analyzers to find hotspots, and recommends keeping draw calls low (avoid 100+), targeting at least 30 FPS, packing UI and distant objects into single power-of-two textures, and minimizing expensive particle systems — illustrated by a production example (Grablay Lords) that reduced runtime hitches.
