I am curious as to why I'm receiving such low frame rate for a map node with no children.
I have 50 FPS when nothing is rendered on the map at all, just creating the mapnode and displaying the viewer. My earth file has no data in it. I can not seem to push above 50 FPS.
I am using osgEarth 2.10, and a high end CPU / GPU. My screen resolution is 2560 x 1600, but even dropping this down to 1920 x 1080 doesn't put me above 60 FPS.
I am on a Linux machine.
I want to know if maybe there's something I can do outside of optimizing my scene graph that could increase my frame rate? Because 50 FPS for nothing being rendered seems low to me and could mean no matter how much I optimize, I won't get better than what I'm seeing when my map is populated.
