They will load as a new area is approached but usually it's not too visible - some sims make them go invisible, some change shapes etc, but we don't do that. If WOFF is not on an SSD drive, try reinstalling to one to minimise. Also panning around a few times can help load in textures and scenery to ease the 'loading load'.
Knocking back the terrain and scenery settings a notch (depending on your system) can help - I just flew now with 4, 4 (WOFF BH&HII), for those settings and it was pretty good here.
In the more southerly regions like Alsace there are zillions of trees so you may notice loading more.
