It depends. Are you putting an event condition on a loop region or a transition region? If you’re using a transition region, is it subject to quantization? And does the event make use of any streaming assets?
If the answer is no those questions, should there be a difference in response time?
I also notice the Cue trigger method is more responsive than regions, even though I’m using the Event Stopped state in both cases. A Cue triggers instantly while the transition region takes up to 0.5s before transitioning.
It would be great to have the same instant transition with regions due to how convenient they are in a more complex event.
