Got, the same problem, "flushing" helps for a short periode of time, till the fps are dropping again. The time till the problem returns is way shorter in citys (1 to 3 minutes), in the woods it takes like 10 minutes till i have to flush again. During the fps drop the textures are going to total crap as well, they loose quality and thier correct shape. http://imgur.com/FWQnAOh There is a Ticket on the Dev-Tracker now, if you´ve got the same problem, pls up-vote it, so it gets noticed and hopefully fixed: http://feedback.dayzgame.com/view.php?id=16986
