There are some new options available, Load whole map at start is worth enabling, also I turn off autosave which was causing a small stutter at every bus stop. Also worth remembering is to enable the "app can handle more than 2GB" with ccf explore, sure you all know how to do it but if not let me know.
I find that it runs a LOT better than the original 2.0. Never thought about the Autosave, as the stutter is pretty annoying! Some maps run better for me without the Load Whole Map setting, whereas some do.
