With Ultra setting it is around 24 to 28
Of course the first mission is in subway maybe if it goes out of subway FPS drop.
I did not try Online mode.

Outside of the subway you can get 35 FPS with medium setting.

I hate the strategy of american companies to show themselves like peace army and attack other countries to give them freedom.
Based on this strategy they have designed this game to be in Iran but they did not do a simple search about Iran.
The cities are like Arabian countries specially Iraq and when you go out of the subway you can easily see a flag that is Iraq flag not Iran and many things written on walls are half Persian half Arabic.
What is interesting for me is that in a demo you can see a colonel is talking to his soldiers and he is saying that our enemy is not the people of this country but in this scenario you must kill people.
