Hello,
OOM is a constant threat to FSX, due to 32bit architecture and ever better addons and requirements.
I have not seen an OOM with the scenery, but I use a lower-than-usual display settings.
Some tips:
-If you are using HD textures for things like clouds, environment... try using a lower resolution. Compared to 4096 HD textures, 2048 use quarter less memory, and still look very good (you are very seldom close enough to see the difference).
-If you use photoscenery of big scale (countries), try to only activate in Scenery Library those used for flight. A photoscenery even in Italy can affect a flight from Budapest to Switzerland or Germany.
If this does not help, please supply more details, what other scenery is installed, where do you fly, at which point the error occurs. We will try to find and isolate the cause.
