High framerate = slow movement bug: http://www.youtube.com/watch?v=twiFByvcBLg If you can't fix this by the next update, at least limit the framerate by default. [Engine.GameEngine] bSmoothFramerate=true MaxSmoothedFramerate=60 It's really painful to me when I see people who are obviously afflicted by this bug. They'll do poorly and probably think the game's movement sucks without ever realizing that it's a bug they can work around.
