I usualy , build both FG osg   and G plib from the same release, mainly to=
=20
check the model compatibility during development.
i can confirm the Martin remark: olders fg osg  and fg plib where giving=20
almost the same performances.
It seems recently (but unfortunately i cannot say exactly when,  end of=20
february ?)  we have lost that performance regarding fg osg.

As i said in my previous mail i now get a difference ratio  of 2.5  which i=
s=20
very important :(
