Quick answer: Unreal Blueprint Event Tick disabled but the component's components keep ticking? Per-component tick is independent - disable per-component or set TickGroup to TG_None.
Performance audit: disabled tick on actor. Animation component still ticks; CPU cost unchanged.
Disable per-component
SkelMesh->SetComponentTickEnabled(false);Each component's tick is independent.
Or use TG_None
TickGroup = TG_None: component never ticks regardless of enabled state.
Audit per-actor
stat game shows per-component tick cost. Outliers are your disable targets.
“Tick is per-component. Actor tick is one of many.”
If you disable tick to save CPU, audit components. Most CPU lives in components, not actors.
