Hey, I've been playing DayZ for a couple of days now and I usually have 30-40 FPS. However, sometimes it drops to 15 or even 10, causing terrible, almost unplayable lag. Last time I received such lag spike I was in an empty airfield. Sometimes I get it even in empty forests. I can usually shoot around in Elektro without any FPS drops from 40. What causes this random FPS lag? Is there any option that I could turn off to solve it? Btw playing on a laptop, if that's relevant. System specs: i7-2630QM Nvidia GTX 560M 16GB ram
