Reply to Audio issues with Traktor Pro 2 upgrade

Are any Windows 7 PC users still experiencing audio issues after the upgrade to Pro 2? I feel like I get less now, but I still seem to get 1-2 small pops or stutters an hour with Pro 2. This is on a core i3, 4gb ram, 500gb HD Windwos 7 PC that has had all the optimization I can believe of done to it. I followed the guide that is stickied at the top of this community , and tried some of my own tweaks. It's very frustrating that this is still happening to me. I have a set to play tomorrow evening for about 3 hours and even though it's pretty DIY at a local bar with maybe 50 people, still doesn't look very professional to have glitches like these.

Does anyone have any more tips/tweaks/tricks to share?
