The option to change your FOV is great and since it is there it should be fully optimised. I wouldn't say it's a direly urgent feature but it should be implemented down the line.

I think definitely a gamma and brightness restriction when dark should be in place but it's essential that the night time in Day Z be improved. Full moon nights in the mod were fine when they worked but often it would randomly turn pitch black.

A functioning night could add a lot to the game.

This needs fixed soon the mouse sensitivity is awful in SA right now.
