hey folks,.. so lets help ourselves out:

here is my solution for low fps / fps in cities (worked for me)

more fps (and sady less range of sight)

set in the dayzprofile file the three params to the values, that fits for your pcs (just try), in my case its:

sceneComplexity=100000;
shadowZDistance=600;
viewDistance=1200;
preferredObjectViewDistance=600;

(every one of this has something to do massivley with fps)

the dayzprofile file is found in:
C:\Users\*username*\Documents\DayZ

and is named:
*username*.DayZProfile

greets and keep watching
