Ah yes, I recall this was discussed a while back. With geode merging enabled, models loaded with the new plugin render at about 86% of the old plugin frame rate. I have one model that has a higher frame rate with the new plugin, but my other models all render slower. Still, this is significantly better than without geode merging.
I assume the optimization pass is not included in the load time displayed by osgviewer? -Paul > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Brede Johansen > Sent: Sunday, July 02, 2006 2:12 PM > To: osg users > Subject: Re: [osg-users] Trialing the new OpenFlight as the default > > Hi Paul, > > The new loader converts face records to Geodes to store > record ID and comment.
