I believe that there is a problem with openLC Europe scenery in the Geneva LSGG area. This has been widely discussed, in particular on Aerosoft and FSDT Forums, both of whome offer LSGG Airport Scenery.
In P3D v5 I have made reapeated attempts to land at LSGG, encountering significant stutters on approach strating at 7 miles and then a CTD every attempt as also reported by others.
Uninstalled Open LC Europe and problem vanishes. Re-install and it returns.
Somethig very odd is going on in your openLC scenery in that area I'm confident.
Please may we have an update so that I can re-install.
Thanks in hopeful anticipation.
