Reply to Problems with CPU i7 - VCI 100 - Traktor Pro

Hi,
I need help. I got my new laptop Sony F12, where I got i7 CPU, 8 GB Ram and newest chipset PM 55 - 1333Mhz FSB. Everything goes fine except Traktor reacts on VCI sometimes late on commands-especially faders and sometimes doesnt at all - like platters.
Please help, I do not really understand what is problem. With old laptop it was fine, even with my netbook.
Cheers and thanx
