Good morning,
For some time I have had the following problem with GSX, particularly with certain vehicles and characters on the taxiways: these are transparent or half represented.
On the web I saw that it was necessary to add the line HIGHMEMFIX=1 in the [GRAPHICS] paragraph of the FSX.cfg file.
Before launching fsx I remove this file which is reinstalled by fsx, I add the line HIGHMEMFIX=1 but I still have the same problem.
Thank you for your help
