I just wanted to give a short reminder to everyone who has OOM errors, to turn off (deactivate) all unused sceneries in the FSX when not flying them. This includes also sceneries which you don’t fly over, though those you fly over are those that impact the VAS at most.
I recently flew through Europe, and forgot to turn off some sceneries, and was plagued by OOMs again. One scenery even loaded 500MB into VAS when I flew over it!
So, just a soft reminder, to myself also, to turn them off, just keep those on that are really relevant – for instance, keeping Swiss Pro activated while flying from England to Italy at 31000ft in a 737 is not really meaningful.
If it helps, the only permanently activated sceneries here are basically mesh, UTX and landclass if you have any, and then the airports I fly from and to. In flying GA or low(er), then also ORBX.
In the page about OOM, you’ll find the explanation for Scenery Config Editor, my choice of a program to manage and turn the sceneries on or off, before even starting FSX.
