Cross DJ too slow!!

Well, I bought this software some weeks ago and I tried to do everything for optimizing and use it with my controller but works really slowly like mini freezes everytime, I tried to search an option in the menu of sync thinking that could be a problem of my VGA but nothing...
I have other programs like serato and traktor and their work perfectly so I can't understand what is going on.
The program is working around 29fps.
