Is the GPU time spiking when not running the debugger? Basically are you getting like 99% of your frames hitting your frame, then 1% that are taking 4-5 times longer than they are supposed to.
I suspect you may have some kind of threading issue. Its easy to see slightly changing the timing of a few calls can put things into conflict over sharing a resource where as before they where not. Seeing if you have a continues load difference versus one with high peaks may help this. Improving batching may help if the conflicts are on the driver side of things... On a somewhat related issue I ran into an a while back where the windows system call: ::timeBeginPeriod was used. This caused the Nvidia driver to dead-lock, with large periodic hangs, and from time to time, just plane crashing. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=71691#71691 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
