This update adds the following...

1. A new, customisable, night vision mode which more closely replicates a monocle system. You can change the size, brightness, edge softness and tint in the Game Settings menu allowing you to replicate a wide range of different night vision modes.

2. Some minor optimisations with terrain textures that should mean the game uses a little bit less VRAM on the Central Libya map. I don't think there is any noticeable performance gain.
