The limitations to vertical field of view are extremely frustrating. I'm allready running on a 16:10 monitor and now the hud cuts even that so I'm down to a pathetic slit. As a result I'm having serious trouble following another ba the moment it jumps as it immediately goes outside the screen and the direction/targeting indicator is cluttered by the hud.
Judging from ba appearance this is all intentional but I think its too much. Make the top/bottom of the hud slimmer and its good. Might want to reconsider the 'out of focus' effect on it as well, its the only thing in the game (excluding zooming but including the rest of the hud...) that does this and as such a bit out of place.
On the bright side the damage effects are excellent (even the cracked glass), this is the kind of stuff that helps immersion (its actually connected to gameplay instead of just being a static obstruction)
Edit: fixed/removed stupid mistake that Flyingdebris pointed out.
