To be honest, even if it is somehow strange: I have a natural barrier against harming females. Could be that this is an antique way of thinking these days but that is what my parents taught me. Even If it just a 'game/simulation' our subconscious doesn't differ that fact at all. I just can remember one game I played a long while ago where there were female characters and I literally felt bad and stoped playing that game, thought it was a pretty good one. Sadly I can not remember its name nor dev-studio.
Giving this an upvote for the fact that AmrA is a simulation, so there should be female characters.

Q: really? stopping from playing a game just because there were girls in it?

A: Sorry, No. But because I had to kill them.

I tested out a lot of settings trying to run on better FPS in ArmA3. They all failed and didn't show any changes at all. My game in SP runs on 'ok' 25-30 FPS in MP on a good hardware server with no bad scripted mission I run 12-15 FPS even with low player and AI count. My hardeware seems not to be used to what it could serv. For example Altis Life RolePlay on an A+ Server runs for me 8-10 FPS no matter if on low or ultra extremly short viewdistance or extremly much (tested up to 10k). Only lowering the viewdistance by the Altis Life RP player menu down to 200m gives me now 16-20 FPS.
