Objectflow_xxx.dll files

[schmit 0]

Hi, everybody

 

A question about how Orbx manages its installed sceneries in FSX.

 

When installing some sceneries ( it can be a region or an airport ) Orbx adds some lines in "dll.xml" file located in :

C: \ Users \ Name \ AppData \ Roaming \ Microsoft \ FSX

 

These lines refer to " Objectflow_xxx.dll " file , dedicated to the installed scenery , and which is in the folder named "scenery" of the scenery :

(example for airport 2WA1, the file is called Objectflow_2WA1.dll and is located in X: \ FlightSim X \ Orbx \ FTX_NA \ FTX_AA_2WA1 \ Scenery )

 

What are the role or function of these dll files, which heavily penalize fps FSX by their successive additions in dll.xml ?

 

I ask the question because after deletion of the lines concerning these Objectflow_xxx.dll  in the file dll.xml , I see no difference in 

Orbx sceneries ( objects to their right place and all animations are running) but FSX FPS jump from 20 to 30 points or more ? ? ?

 

Thank you for any information .
