I think there is a few more issues which are realy important such as FPS drops and low fps, high ping and a few more but they can be fix fast because before 0.5 version we had a good fps.
We're looking at all of these for the launch patch (and have talked about a few in dev blog posts over the last few days). I don't work on any of the groups directly tackling these issues, so I can't give much more context than that, but rest assured we're aware of these and working hard on resolving them.
