Hallo jormapaappa1235,
thanks for your comment.
I had already done that 'Decimate' test, and my personal conclusion was that the outcome was not influencing actual FR increase that much.
Please check the two images (sorry about the size; I'm new to dropbox; next time I will insert smaller pictures):
These screenshots were taken on the same LATEST 777 Seattle model, in the same, identical, conditions: in the second one, I applied the Decimate Tool to ALL the indicated objects, by reducing the number of faces by a rate of 60% (just as a test). Those 7 objects - on that particular view - would of course be responsible for the high faces count.
Result: from a 58 FR, we go to 59; that is, a FR increase of 1,01 %.
That's why I deemed 'Decimate' not the most appropriate tool. At least, it was not what I was looking for...
By optimizing the Seattle model as I have previously reported, I got a factor of 20-25% increase...
The 'performance problems' seem to have been somehow resolved by the latest optimization. As you may see, my actual FR is 58, on that particular view. Actually the Seattle Team is receiving confirmations that the aircraft flies nicely, now (being, nevertheless, an obviously 'heavy' model).
As I said, there are other resources which must be taken into account once you fly with FG 3.0 (as the new scenery, just for instance), AND heavy models: in the near coming future, we all will need more performing platforms.
Once I will be finished with further Cockpit development (New EFB in a while; then, the CDU), though, I will probably try to 'polish' things up a bit, giving another try to the 'Decimate' tool...Our planned First Release, will be more complex (that is, 'heavier') and more optimized (that is, 'lighter')...we'll see.
It's a matter of dealing with compromises: as we say, you can't get all you want...
Thanks for your notes,
I-NEMO
BTW: a modern aircraft's Cockpit is much, much, much more complex than a car's one...
