Well done Duci!
I thought the stock 1.3 visual sighting settings were quite steeply in favor of the AI since they seemed to spot my scope up from miles away even if only for a few seconds. I just halved the Visual sensitivity down to 0.05 and dropped the sonar's thermal layer attenuation down to 3.0 so the layer isn't quite the wall it used to be.
My preferences, of course, but I'm golden. Didn't have to tweak or dig up hardly any extra mods.
Thanks man!
