The Navmeshtool program comes with OpenMW and can be used to pregenerate navmeshes, thus avoiding loading pauses in game that might have been caused by doing that on the fly. It's an easy, convenient way to eliminate one category of stuttering (while continuing to enjoy the benefits of what caused it: dynamically generated navigation meshes).
Please view the tips page for the navmeshtool program for usage instructions.
