Eyefinity doesn't work properly. Eyefinity is ATI's technology for using three monitors on one video card.

My resolution is 5040 x 1050 (three 22" monitors).
By default, the delete, end and page down keys on the keyboard change the FOV to be 30 60 and 90 degrees. These are not nearly wide enough to be useful. A FOV of at least 120 - 150 degrees is necessary depending on the resolution.
If there was a way to support three monitors (as the DCS games do extremely well), it would be fantastic. Allowing a custom FOV would be the easiest way to add support I'd imagine though.
