Traktor Pro 2 lagging problem

[fxsw]

Hi guys,

I'm experiencing some trouble with some songs lagging into the track decks when I'm playing 2 songs at the same time.
I've covered the CPU and beatmaching problem.
I have the last version of traktor pro software so it can't be because of an update that I have to make.
I tried to close all other applications, restart my computer, turned the wifi and bluetooth off.
I unchecked "enable the multi-core processor support"
Still lagging...

Don't know how this fix this issue and it drives me crazy, I have an important gig coming soon and It HAS the work
I'm working on Mac OS 10.9.5 with a traktor s4 mk2 (soundcard integrated)

If anybody experienced the same problem and found a solution please help !

Peace.

Are you sure your latency isn´t a bit too low? Try selecting your Mac's audio interface in the settings to check if the problem is your S4 or the software
