Lag spikes not only in game, also on menu screen

[MGAD 1]

I have noticed lots of people complaining about lag on BE servers, but i don't think that is my problem...

 

I lag everywhere... in a BE server, in a non-BE server, in the menu... Between spikes, i get glimpses of a very smooth game, but longest i've been able to run the game smooth without spiking is about 8 seconds.  I have tried to lower everything to the weakest quality, it makes no difference watsoever except for the fact that...well, everything gets uglier.

 

If anyone has a clue on how to fix that...

 

I have tried the verify your files/validte your files thingy in the properties of the Steam library, fixed nothing...

Followed someone else's suggestion for another problem, turned off my antivirus...

 

Game is all fine now...

Try decreasing the resolution distance - I had the same issue on my work PC (a lower end but still solid desktop compared to my home gaming rig) and I tried dicking with all the settings until I ran out of stuff to lower/disable and then I saw a drop down menu (forgot it's name) that has like a screen resolution with a percentage next to it. I dropped it down a few notches and now I get to play DayZ at work haha.
