That's a tough question. I never use the Event Camera, but always have External View turned on. I mainly use it to look at cool stuff, but try to never use it during combat. That said, there are different types of realism. I never use full manual targeting, as I have no math skills at all. I leave myself open to enemy attention by having Manual Targeting turned on, but use the Weapons Officer to get snapshot details, which means putting the 'scope up every couple of minutes to update the information, so while my Difficulty level is lower, the Realism of risking being spotted is high.

Or so I keep telling myself.
