The 50-90 ms UWorld::Tick spikes were the TG_EndPhysics barrier waiting for physics-scene completion while all 8 TaskGraph workers ran BackgroundHigh tile tasks. Near and horizon tile generation now run at ETaskPriority::BackgroundLow (helper lanes background); queue depth and the 8 workers are kept. FI: near set 2.11 s (10 runs), max UWorld::Tick 21 ms, max EndPhysics->PostPhysics gap 16 ms; SW: 1.32 s, 11 ms. A hard 7-task cap removed spikes but doubled settle time. World unchanged. Fast tier PASS; Linux UE host builds. R44 notes (exact passage restructuring: only a full-composer z-column SIMD kernel could plausibly reach 3x; smaller exact pieces ~1.1-1.2x each) attached.
