If you mean the area you directly look at seem dimmer than the surroundings, then yes.  It drives me crazy as well as aircraft seem smaller at distances now.  Before I could see aircraft about 20+ miles away, now, I can barely see them at 6 miles.  I also get tons of stutters no matter what settings I use.  Some quick systems specs I am using are, Intel 10850K, 64gb of 3600 ram, RTX4080, and DCS is on a Samsung Evo+ by it's self.
