Recently I have been experiencing "lag" or "sticking" keys in Battlefield 4, where the keys stick in game, but not real life. It's gotten to where for 3-5 seconds I cannot move, or the keys I was just pressing down stayed pressed down. This has only been occurring recently and my keyboard is spotless, no sticky things on it. Also, I tried another keyboard, and that one "stuck" too. It's a Razer Deathstalker.
