A quick and dirty assessment of the Basic Unreal Engine Nav mesh performance and behaviours, with many RTS Units placed on it.
RTS games typically require specific pathfinding algorithms to manage large number of units behaving on the map.

This video demonstrates the behaviour of some basic units on an Open World map, built with the Unreal Landscape editor, and the built in Nav Mesh applied. The units are then simply controlled by the AI Move To Nodes.

The overall performance appears at first sight reasonable, with Units moving about reasonably freely. However it can be noted that some units get caught in none navigational areas, either by directly spawning in a localised nav region, or being bumped into an off navigational area by collisions with other units.
