OK I've properly tested this using NVIDIA Surround, the game is natively horizontal plus and correctly adjusts the FoV for multi-monitor systems, the FoV slider also works correctly, changing the multi-monitor FoV with it.
The only notable issue is the in game HUD, the issue is that the HUD is scaled based upon the width of the monitor compared to the aspect ratio. Since all multi-monitor resolutions appear under 16:9, a triple 16:9 setup triples the size of the HUD, since the UI is centred this means the top and bottom 1/3 of the HUD are not rendered on screen.
There are a few ways to fix this, firstly, the easy way is to bind the HUD scaled based on the resolutions height rather then its width, this will means part's of the HUD will bleed over on 3x16:10 but it's better then not seeing the HUD at all.
Second option, give everyone the ability to define the HUD scale.
Third option, probably going to be the hardest, but allow the players to define horizontal and vertical offsets from the sides of the screen, see games like Strike Suit Zero and Battlefield 3 and 4 for examples of this.
