I've different problem with XP/nVIDIA 8800 GT. In debug code, when the
stats are on while exiting the app sometimes there is a crash. I happens
in most of the osg examples. The release code works. It also happens
with old OSG1.2 code, and it didn't happen on nVIDIA 7950. I first
thought it's the driver setting, after playing with I thought I got rid
of the crashes, but I didn't. Then I suspected osgText, I thought it
might use driver capabilities for text, but it doesn't, then I suspected
the font, when I used the default font it seems to crash much less
frequently. Finally I gave up. Any knowledge about this issue will be
helpful.

 

Thanks,

 Guy.

Hi again,

 

Just out curiosity can anyone with two monitors check if this happens
with his setup ? I made this test on XP/GeForce 7800 GTX and
Vista/GeForce 8800. If I have two monitors active draw time degrades if
only one monitor draw time is stable. 

 

Thanks in advance,

Wojtek

        Thanks Serge,

         

         I have to withdraw my claim. Your mail gave me something to
think and I checked whether problem exists in single monitor mode. 

         

        I turned off my second monitor in Display properties... and
Tada! - problem vanished. Framerate is stable. 

         

        This is not the first time I observe unusual OSG/OpenGL
behaviour in multimonitor mode. I guess its the drivers again. Sometimes
changing NVidia multimonitor/mutihreading settings help but most often
it does not...;-( 

         

        Thanks for helping to isolate this issue,

         

        Wojtek

                        We noticed another issue. When statistics bars
are on - framerate slowly
                        degrades. This happens with osgviewer
dumptruck.osg for example. When stats
                        are on draw time slowly grows and framerate
starts to decrease.
                        
                        Tested with latest svn (2.3.4), windows xp &
vista, OSG built with VS 2008.
                        
                        Regards,
                        Wojtek

                         

                
                Hi Wojtek,
                
                I've just tested it (latest SVN, WinXP but VS2005,
NVidia 8600GTS), and there is no decrease here, my framerate stay at the
same value (tested with vsync on and off). Have you noticed this problem
with VS 2005 too ?
