General Question about Audio Dropout

Is it safe to say that generally speaking Audio dropout is cause by lack of PC resources?

At the risk of hijacking this thread (let me know if I should move it to another thread),
 
In an effort to declutter and consolidate I've gotten rid of 2 desktop machines and an old laptop and bought a brand new Dell XPS 13, 16GB RAM and a 500GB SSD hard drive running Windows 10. I'm using a Behringer U-Phoria UMC404HD USB Audio interface.
 
I've uinstalled McAfee, killed Dropbox, One Drive and suspended Carbonite. I have uninstalled all the Dell support stuff that came on the machine.
 
I've installed Sonar X1 and loaded up some of my old projects that ran fine on a very old desktop machine.
 
The Audio Engine will stop immediately when I try to play any of my larger projects. I opened up a very simple project that just had 2 guitar tracks and the playback is horrible, very warbly.
 
I can't believe the resources on this machine are taxed to the point that Sonar cannot perform at all. I'm sick thinking that I just threw away $1500 on what I thought was a killer laptop that should last me for years.
 
I'm hoping there's just some configuration work I need to do to salvage this.
 
Thanks in advance for any help,
 
Greg.

I'm a longtime SONAR use ( back to ProAudio 7 actually) so I'm not trying to be a hater when I mention this...
but I've usually had fairly robust machines..not the latest greatest but not sh*t either. 
I'm sometimes frustrated when I have a project with 15-20 pure audio tracks and maybe 4 or 5 soft synths and do a quick edit while the transport is running ( maybe slip edit a clip or delete a portion) and SONAR can still cough it up and dropout. Maybe I expect too much, but it always feels like I SHOULD be able to do those things on the fly without SONAR dropping out. It's really the only thing that ever makes me look over to the dark side and consider switching.
Again..love it in general, but it does seem dropout prone. 
(PS...my current build is lean and tests well with Prime95 and latency mon...still get more dropouts than I think I should....)

have you installed the drivers for your Behringer Audio interface ?

Yes, I did but I had to install the 2.23.0 version because the installer for the 3.29.0 version hung. I found a thread where the user had the same issue and remarked that installing the 2.23.0 version worked for them.

It's not the default settings at all. 

Bet you will still have to tweak Aud.ini.

It is not a problem. On the contrary, I suspect it is necessary to tailor the file to your system and wonder if those experiencing drop out problems have tried tweaking the file.

By the way, I just bought Camtasia to produce some Youtube videos on 'extreme' Reaktor projects.
Reaktor is single-core, so to get more oomph one needs to split into tracks.
I plan to demonstrate how-to's for Sonar, Live and Reaper. It is very interesting to see how these DAWs handle track splitting into multiple CPU cores, the impact of hyperthreading, etc.
Camtasia, unfortunately does not support ASIO, otherwise it is a fine product.
I hope to have something ready in the next few weeks.
Look for it here:
