But while the field of view is increased in the game itself, the menus are cut in height.
The game was also test run at maximal graphics settings and different resolutions. The Geforce GTX 295 that has been used for the tests delivered more than 40 fps if the resolution is set to 1920 x 1200 pixels or below.
