15-20 or more .
i only get 10 fps outside in the single missions, where there are a huge task forces ,15-17 in training missions.
I suspect about submarine and ships and not the enviroment as a major Fps factor
curiosly the museum is smooth as silk

, the place in sh4 with more fps.
Now with 1.2 the graphic quality has improved a lot, but not the fps,
sometimes the difference in using enviroment on/off is too small.
