Well, on this evidence I just done a completed update on OSG/SG/FG... and back 
I go to 5 fps at KSFO.

Also now I do not see 'sea' outside the tile I have - here is the scene at 
FHAW (Ascention Is. right in the middle of the Atlantic).  You will also see 
I have 13 fps here in the PC - before I used to get upward of 43 FPS here.

Something is wrong.

Hello Mathias,

Your 10-20 frames more, seems to me very poor regarding the comparison, 
i get from 10 to 15 fps with the recent one and a now with that old one i 
recover from 60 to 85, which is a huge difference.

BTW: with the same FG version built PRE_OSG_PLIB_20061029  
i get a lower frame rate 
from 55 to 75 with every options activated (3D clouds, Shadoww, .)
Theses differences indicate that FG OSG could be equivalent to FG PLIB, 
probably better.
That dramatic loss of performance with the lasts OSG version, is not normal.

Hello Gerard,

 Hello Mathias,

 Your 10-20 frames more, seems to me very poor regarding the
 comparison, i get from 10 to 15 fps with the recent one and a now
 with that old one i recover from 60 to 85, which is a huge
 difference.

I get an performance increase from about 80/90 fps to 100/110 fps. My 
average frame rate is about 90/100.

So in my environment which is probably not that different to yours 
(except hardware) I do not have a performace decrease with OSG that 
some people and you described here.
I don't use any fancy optimization parameters: -march=k8 -O2 -pipe, 
that's all.

What is your environment, and what are your compile parameters?

Regards

Matthias

Hello Georg,

Because,  i have a lot of backup  (SG/FG/OSG) , i did rebuilt FG with an older 
OSG (10-04-2007) i had kept.

Not from a new download 


The best, i guess, for you is to download from my URL the sources.

I have built a tar.gz file  which contains
 OpenSceneGraph, OpenThreads, Producer

all of them from cvs/svn  10-04-2007.

here the link

 That issue  remark look like an other previous topic Frame rates.

 As far i could understand in IRC , that problem could be solved when using
 an older OSG cvs version.
 I have tried to find which OSG cvs version could suit to our request.
 I did not find any.

 Is it possible to have an official OSG package working with  the recent
 SG/FG cvs, in order to have an acceptable frame rate  ?

I solved the issue (so I can at least use FG/OSG again) by using the last OSG 
CVS version (not SVN):

OpenSceneGraph Library 1.2

But I had to remove the call:

camera-setAllowEventFocus(false);

in redout.cxx and splash.cxx to get it to build.

I am surprised nobody using CVS/SVN FG/SG/OSG reports this issue (or replied 
to this) - there was a lot of chatter about it in IRC.

I'm using osg-svn which is a couple of days old on Win XP, P4 2.8, 1.5 Gb
RAM, nVidia 6200 256 Kb RAM. While frame rates are not good, and are a bit
down on earlier versions, it's usable with 25-35 fps at KSFO with the
Hurricane.
