I confirm this as well...the game is now unplayable, and before 1.7.5 I did not have this problem. However it seems there is some people unaffected by this glitch, I have a friend with the same version and all that and he does not suffer from this heavy lag spikes every 20 seconds or so, BUT, he started playing a few days ago and he directly downloaded the 1.7.5 version. My guess is that uninstalling everything and installing again could be a possible fix (no idea, i haven't tried, i fear of loosing my current character, or waste my time), because it does seem as if new people who just download and start to play dayz starting with version 1.7.5 do not get this lag bug. Can anyone confirm this? I beg the developers to put high priority on fixing this lag issue, cause it makes the game unplayable, I'm quitting it until this gets solved, you are totally screwed when zombies spot you and you start lagging up...and it also makes me rage much.
