This is very strange, I own a sphere AF, this camera is very similar to the pro9000, and by disabling "Exposure, Auto Priority" I can easily get 30 fps, although the image gets quite dark. I guess that to get a good balance between image quality and fps you need to adjust exposure manually, with guvcview you can use control profiles, this would save you time adjusting controls in similar situations.
