Hello, OSG is a great product and I hope I can tap into the great support you folks offer!
I have an Intel Core 2 Duo processor, and I'm running OSG 2.8.2 on Windows XP. And I have VSync turned off, by the way. When I run osgviewerd.exe (debug) I notice that the stats reported are very erratic. That is, the graphs displaying the Event, Update, Cull, Draw traversals are not "flat line" but go up and down unpredictably. I get ~100 fps. If I go into the Windows Task Manager and set the affinity of the osgviewerd.exe process to a single core, then the stats flat line and my framerate goes way up (~160 fps). Running osgviewer.exe (release) with affinity in the Task Manager to both cores yields flat line graphs and frame rate ~200 fps. Obviously, 100 fps is more than enough, but that is for a simple scene. In our application, which embeds OSG into an MFC window, I see a framerate of about 20 fps in debug. My colleague, who has a quad core machine, sees about 3 fps in debug! Is there something we're not understanding correctly about how to load balance OSG across multiple cores? We don't want to limit our application to one core because then we obviously lose parallel processing (database pager, etc). I really appreciate any help you guys can offer. Thanks, and keep up the great work! Jesse Stimpson
