The particular line disabling the OSG cache has been there from the very first commit (3 years ago to the day). So there is a chance, it was never really considered - or there was an issue with OSG library itself at the time. On my machine it seems ok to enable the cache - everything looks normal with FG. Maybe someone could do some tests when changing the setting (SGPagedLOD.hxx:56) from "CACHE_NONE" to "CACHE_IMAGES" or even to "CACHE_ALL" (then recompile/install sg+fg). Would be interesting to know how this changed loading times, run-time fps and memory consumption. Just make very sure to use a well controlled environment for any performance tests (especially no live weather...). cheers, Thorsten ------------------------------------------------------------------------------ Enable your software for Intel(R) Active Management Technology to meet the growing manageability and security demands of your customers.
