Hey guys, I played during release and I remember this issue, but I forget how I fixed it (or if I even did). My Mumble push-to-talk key is Left Control. If I am talking on Mumble and try then to move, I cannot. Is there a passthrough option or something I am missing?
You may have to go through your in-game keybinds and make sure that Ctrl is not bound to any of your movement keys. If it is, then I think the game would take that as priority over the PTT binding.
