lose control of character for about 3-5 seconds about once a minute . (PC)

I have the same problem, first occasion is pretty much the first time I spawn into a new map and then it happens the same as for you (every so often). Obviously some component of my system is overloaded at that time but the fact that it only happens intermittently rather than all the time suggests my system's good enough to run the game and that this is a fixable software issue.

@ragnarok013 Hmmm... I do have two keyboards connected, I will try removing one, if it helps I will report back.
