HonsterI mean using the in game chat window with a key bound to say_party. It only works if youre in a party with someone. I didnt try using the main menu party chat input so I have no idea if it causes hitches.
Edit: I also stutter/hitch when receiving party chats. My game doesn't hitch when sending party chat through the main menu UI chat box for some reason though.
That's weird, I don't know what to tell you. I can only say that I don't experience it and I have not received reports of anyone else experiencing it, but I don't get reports of much of anything anyway.
