I have been bought DayZ on Steam Summer Sale 3 days ago.
My problem is the mouse input lag which is making the game unplayable.
For example when I am looking around with my character using a mouse it has a delay like 0.2 sec but only in game. In the inventory or in the menu there isnt any lag.

I tried:

• every graphics settings from poor to extreme my fps is always above 100, sometimes in bigger cities going below to 70-80 but its not the main problem.
• I am playing with a zowie ec2-a mouse on 400 dpi, tried another mouse it doesnt fix the problem
• turned off mouse acceleration and smoothing in windows and in-game too didnt help
• edited config file like reduced view distance etc. didnt help
• vsync and anti-aliasing turned off everywhere
• reinstalled game and win 10 too didnt fix the problem
• watched tones of videos what can be the problem but didnt find any ideas to make the game playable
• windows defender antivirus i reinstalled pc a week ago probably dont have viruses on it
• every other game is working correctly like csgo, pubg, rust, cod

Im not laging only have this mouse input lag, can you guys help me what to do?
