PROBLEM: Active Track stutters when loading second Track

Hi, I have a new laptop, a Dell Inspiron 15 7000 series, running Windows 8.1. I installed rekordbox 3.0.1, it all seems to work fine, but when I use the 2-deck mode and have a track playing on one deck and then load a track on the second deck, the playing track stutters for a 1-2 seconds. I tried various buffer size and sound card settings, but it doesn't seem like it is working.

Can anyone help me with this?

Regards,
