Slow performance
 

I´m running two LG displays that work quite fine except that the one using displaylink is substantially slower than the other one.

Now, I have had an installation of windows 7 on the same machine using boot camp and installed previous driver versions where performance was almost flawless, but when I switch to OS X 10.8.4 performance turns into crap which shows that the issue is driver and software related.

Even when I upgraded drivers to 2.0 and now this beta its still the same - any one else experienced the same?
