Event Tick performance loss?

Hello, still new to Unreal Engine and was curious about performance loss using Event Tick. Is it better to use one Event Tick on a controller/player BP and have multiple hit results or is it better to have the Event Tick inside each specific BP as needed? Which costs less performance? Thank you in advance

Event tick in itself doesn’t cost a lot of performance it is what you do with it that drains the performance. In most cases you won’t need things to happen on every frame anyway and then a Timer is better than Tick. What you suggest though is true as it is better to have one Actor tick and do it all than having many Actors do their own tick.
