It works now ! Tanks !

If you want to set it into your code, you should try something like: viewer.getDatabasePager ()-setScedulePriority(OpenThreads::THREAD_PRIORITY_*); (setting THREAD_PRIORITY_* the value you want). -- Serge Lages http://www.magrathea-engine.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Thanks. Christophe 2007/8/27, Adrian Egli [EMAIL PROTECTED]: Hi Robert, i will test it on my OS/X system, than on the same system with windows XP (dual core), i hope i can do it tomorrow.

Hi robert, the performance is better now with the fix you did. regards 2007/8/24, Adrian Egli [EMAIL PROTECTED]: Hi Robert, i did the first test and it's seems working.
