Hello, Thanks to Holger Sandmann here is a "hotfix".   This will solve the stutters at Clacton but will also remove the Vector surf effects.   Either: Move your special effects slider to zero   or: Please go to ORBX\Scripts\unified\regions and back up terrain_global_v.cfg. Then copy the attached version into its place. Run FTX Central and wait for it to Activate Orbx scenery. terrain_global_v.cfg
