Strange water mountains a few clicks east of London …
You need my free add-on works with all the orbx sceneries if you have them just check out my instruction in the description. River Thames Water Fix (no google imagery and no performance impact) for Microsoft Flight Simulator | MSFS
Have literally fixed the entire Thames river through London.
I have no ORBX sceneries installed …
Sorry I mean it works with or without the orbx add-on’s there are different versions within the zip file.
Had to make two versions because of differences around London city airport the rest of the add-on is the same.
this is the folder you would add to the community folder: thameswater for default&londoncitypack
and delete the - thameswater for Orbx EGLC add-on folder.
Of course you don’t have to use my add-on but it fixes what your seeing.
