I typically get 70 to 80 fps with 2 D clouds and I had the frame rate throttled to 30 fps when I got the 1 fps with the latest 3D clouds. But I just tried running with 3D clouds and real weather fetch at KLMO and got 16 to 21 fps. > >> Also for both 2D >> and 3D clouds, the field elevation is not accounted for in applying the >> cloud base MSL height.
