Hi,
I use my laptop i.c.w. my Native Instruments Traktor S4 MKII controller (DJ controller). For software, I've got Traktor Pro 2 installed. Everything works fine, BUT sometimes it looks like my laptop can't keep up. It means that played tracks suffer from small breaks.
The minimum specs asked by Native Instruments are an internal (RAM)memory of 4 GB. My laptop has 6 GB, of which 4,9 GB are available. Below you can see some print-screens from my task manager while using Traktor software. This may be helpful?
