I'm getting a weird error of sorts, I really don't know what to call it. A small text window pops up in the top left corner of my DayZ game, and it's measuring all of my keystrokes, and seems to lag/freeze my game with an annoying beeping sound. http://i.imgur.com/L71pK.jpg I included a screenshot. Does anyone know what this is and how I turn it off?
