I get framedrops from 30-40 to 0 for 1-2 secs every 10-20 seconds.

I have tried every possible setting, even with everything disabled and all graphics options on lowest possible. Also tried modifying dayz profile files, to whatever people suggested on forums as follows:
GPU_MaxFramesAhead=1;
GPU_DetectedFramesAhead=1;

sceneComplexity=300000;
shadowZDistance=100;
viewDistance=2200;
preferredObjectViewDistance=1800;

Launch options:
-cpuCount=8 -nosplash -noPause -maxMem=6144

tried with 4 cores aswell (software supposedly detects 8 cores with I7 dunno if true)

Feels like these setting keep resetting(100% sure i save them)? set sceneComplexity to 20000 as lowest, still no difference.

Computer specs:

Intel core I7 2600 (2,67GHz)
HD radeon 7850
game installed on SSD
Logitech G510 keyboard
Logitech G35 headset
Razer naga mouse
some random logitech speakers
I use 2 screens (tried unplugging 1, didnt solve the problem)

Everything on my computer has 100% up to date drivers.
Only running steam,logitech keyboard software, skype and Security essential on the background.

also tried reïnstalling, didnt do anything for me.
