Re: [osg-users] Significant drop in frame rate when updating from OSG 3.2.1 to 3.4.0

Hi Werner, Great to her you got to the bottom of this issue, amazing how such a small and innocuous looking change can have such a dramatic impact. BTW, the short hand for setting the binding in OSG-3.4 onwards is: geometry-setNormalArray(array, osg::Array::BIND_PER_VERTEX); The separate

Re: [osg-users] Significant drop in frame rate when updating from OSG 3.2.1 to 3.4.0

Hi Robert, final analysis: In our software we did the following patch to make it run with high fps in master of 3.4 branch: osgNormals=newosg::Vec3Array; +osgNormals->setBinding(osg::Array::BIND_PER_VERTEX); geometry->setNormalArray(osgNormals.get());

Hi Robert, the 3.4.0 tagged version is OK with the frame rate. We discovered your commit in the 3.4 branch causing the problem: From1f1c21772ae0dd10a93cd31ab81bf563802b7b2dMonSep1700:00:002001 From:RobertOsfield Date:Thu,3Nov201611:31:07+

Re: [osg-users] Significant drop in frame rate when updating from OSG 3.2.1 to 3.4.0

Hi Robert, I have done 1 week of testing now on the dramatic performance issue. As I said, when linking my program against osg 3.2.1 I get 60 fps and linking the program without any change against version 3.4.0 I get 2.5 fps. Exporting my scene and running it in your viewer in 3.4.0 also has

Re: [osg-users] Significant drop in frame rate when updating from OSG 3.2.1 to 3.4.0

Hi Werner, Hopefully others will be able to chip in as I don't have a answer right now, it's certainly very odd. If it were a general problem then we'd seen lots of issue with it being reported. With this level of slow down it's almost like your'e invoking a software renderer when running with

[osg-users] Significant drop in frame rate when updating from OSG 3.2.1 to 3.4.0

Hi Robert, I updated my project from version 3.2.1 to 3.4.0. I'm on Window 7 Pro. Unfortunately the frame rate dropped significantly from 60 fps to 2.x fps. I verified it several times by just linking to the 2 versions without any change of my code. Please see the 2 screen shots with the stats
