OK, I downloaded and installed the scenery config tool. Thank you.
Now, I'll have a look and see how it works.
I read in the users instructions that it could also help to get the loading up time down, but that it was not proven.
Lately (since I bought the majority of the ORBX sceneries at the X-mas action), I noticed indeed that I have to wait minutes before FSX really starts up. Most of the time seems to be spend from 70% on, when it says it is loading up the autogen scenery.
Any explanation for that or ways to get around it?
Cheers.
Marcel
