Can you remove them with the object editor? Wow you must be getting like 10 FPS there. Outerra seems to chug when there are models. I don't know why. The terrain has thousands of polygons, but when it comes to a few polygons in a model, boy do the FPS go down. On the "Temple" location, just deleting the helicopter that is there took me from 17fps to 23fps. Pretty harsh.
