Hi All,
I had the same issue, and believe it or not, uninstall the ORBX NZ Mesh and see what happens. 🙂
I was also having huge FPS drops down to the point when on finals i had to quit the game. after a long time I uninstalled NZ Mesh and all was well.
Reinstalled Mesh, same issue... I've reported it to ORBX but it seems to be a first for them, so the more reports the better.
