When using Montage Notifies, this property determines how the Notify is ticked and executed in regards to its accuracy and sequential ordering. You can select either: Queued, which is a less precise, asynchronous, but more performant ticking method. Select this if you are okay with minor frame inaccuracy when your Notify executes. Branching Point, is a more precise, synchronous, and higher-cost ticking method. Select this if you want to ensure your Notify executes with maximum frame accuracy, which can be useful if you are using the Notify to execute other events in a controlled sequence. For example, Branching Point is useful when making gameplay-altering decisions, such as branching a decision based on this Notify.
