High preset working for me around 80-110 fps.
i7-7700k@4,8Ghz
GTX1080FE
16GB DDR4 3200MHz
Nvidia driver version 411.63
Win10 Home build 1803

Is that inside or outside of cities and how populated server? @Edqar

Even on high preset on 60 pop server I was getting max 70 fps and I'm 100% sure there are micro stutters aswell because I know 70fps isnt too bad and not too hard to get used to be but it's different kind of lag and it's giving me motion sickness, can't play the game more than 10 minutes before my head starts to hurt, such shame.

I have similar specs and have the same issues. I used to play in Ultra-4K but have had to drop down to 1920x1080 and still get low FPS in some areas.

@DUHDUM
Have to say that i have not visited big cities. Smaller ones are okay.

Hey devs, is there any information I can provide? I've been using the same settings since the early Stress Tests and rarely dropped under 100 fps whether it was a city or a forrest but ever since 0.63 went to Stable I've had this issue.

I have tried verifying and deleting DayZ folder in Documents but that didn't help, I haven't tried reinstalling the game yet.
