Reply to Driver Asio4all

Hi guys!!
I have a big problem.
As i wrote in the other topic i've been having a problem with my vestax vci 100 and my netbook.
In these days i noticed that Traktor doesn't work if use driver4all. They make it work too bad. But if i use the embedded sound card it works fine. The problem is latency. It's too high and i can't do any mix.
How can i solve this terrible problem?
Could it be a RAM problem?
Thanks.
