Does anyone else experience low framerate when they approach/explore terrestrial planets? My FPS is around 20 or higher when I fly through interstellar space, approach stars/gas giants and go through nebulae, but when I arrive at Titans, Terras or any other world with a solid surface, my framerate with be a maximum of FOUR. I'm still able to explore, but it's fairly annoying.
When I make my window MUCH smaller, the frame rate does go up a significant amount, but then the information of the world literally covers the planet itself, and it's difficult to see anything. Therefore, making the window smaller is essentially useless. I've decreased LOD to -2, compressed textures, read recommendations fro the SE forum, and my PC specs are good enough to run the program. However, I have notice that my CPU is 1.80 GHz, and not the minimum requirement of 2 GHz; everything else is good to go. Could the 0.2 difference be just enough to choke my frame rate? If not, what can I do to solve my problem?
