My DayZ config folder

Hello,
Ever since BETA build went to Stable I've been having massive FPS issues, in cities I used to have 100+ FPS like 98% of the time and now I can drop down to 50 and even lower, sometimes even outside of cities it's hard to keep it over 100 which had never been issue in previous Stress Tests.

When EXP Beta was in Stress Test and Experimental build the FPS was fine but once it made to Stable build it was messed up, not just for me, for many people.

i5-6600k@4,5GHz
GTX 1080
16GB DDR4 3000MHz
Both Windows and DayZ are on an SSD
NVIDIA drivers version 416.94
Windows 10 Pro 64bit, Version 1803, OS build 17134.345

What I've tried so far:

Trying older NVIDIA drivers - didn't work
Verified files on Steam and deleted DayZ folder in Documents - didn't work
Uninstall and reinstalled DayZ - didn't work

So I found something very strange aswell when testing, I used to have 100+ all the time but now the norm is like 60-70 and sometimes higher but for some reason sometimes it's ultra low, down to 40s and even changing graphics settings doesn't change anything.

When I first finished testing different settings inside Cherno, server restarted/crashed and after that I had that super low fps.

Before server restart: YOUTUBE VIDEO LINK
Poor preset: 94 FPS
Low preset: 80 FPS
Medium preset: 83 FPS
High preset: 83 FPS
Extreme: 63 FPS
Extreme with HW AA turned from High to Low: 84 FPS

After server restart: YOUTUBE VIDEO LINK
Poor preset: 57 FPS
Low preset: 55 FPS
Medium preset: 56 FPS
High preset: 53 FPS
Extreme: 50 FPS
Extreme with HW AA turned from High to Low and Clouds disabled: 46 FPS

Also did a FPS test in Elektro, YOUTUBE VIDEO LINK, varied from 60 to 90 while I used to have stable 100+ inside Elektro, anywhere.

These were all tested on Trump's Wall 100 player server but I have the same thing happening on any other and official servers.
