In realistic mode, I'd like to see the areas I can't see the enemy in to be slightly grayed out.

Ok, now please go add that to the other topic caleed "Actual Realistic Mode" and delete this topic.

No, IDF-Ripsta.
This isn't a suggestion for a new kind of Realistic mode.. just an improvement!

And I like it.

Hmmm... sounds kind of cool.

does it matter?no need for the fog effect if you cant see anyway.

Yes there is, it would be easier to tell if your sight is blocked with a fog of war, so you know where to look.
