[osg-users] Framerate vs stats?

[Wojciech Lewandowski]

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

      Hi Robert,

      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.

    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 ?
