Realism settings

[RERomine]

That gets into the realm of opinion. Look at it this way, if all your settings are at 100%, you and the AI/opponent are playing by the same set of rules.

As far as hitting with RPGs, it really depends on which one you are talking about. This is accuracy information for the RPG-7V is roughly the following:

Range Percent
50m 100%
100m 100%
200m 70%
300m 35%
400m 12%
500m 5%

This is with no cross wind, clear LOS and an unsuppressed and stationary gunner. That comes out of a TRADOC bulletin on the weapon. I can't say my experience with it has been far off, but I haven't been on the receiving end of it lately.

As far as TI goes, I tend to agree. My experience with it showed it worked very well and should have an edge over the M1 eyeball provided the tank is looking in that direction. It does require a heat differential however between what you are looking for and the environment. If the ambient temperature is same as that of a person, it won't worked that well.

Most people play with them all at default but & relating to your other thread & Suhiirs comment. You can adjust.
To simulate bad weather night etc apart from lowering vision range sometimes reduce spotting ability & on odd occasions to hit chance.
Reduced spotting tends to effect seeing infantry more than vehicles in my opinion so I do not see how it will help you. As Suhiir said if anything spotting might be to easy but the general concencess is default settings are about right.
Speculating here but sounds to me like you are trying to go way to fast if you keep driving vehicles into RPG range. Reduced spotting means you have even less chance to see them. Try diffrent things & perhaps thinking of what they are doing in real terms will help.
That APC with limited vision slits is driving up to a woods at 30mph are they going to see people in it? Are the people in the woods going to see the APC?

I did a post ages ago try searching tactical hints or tactical tips some of it may help
