Sonar X vs. its hostile environment (a crowd intelligence troubleshooting guide?)

I have been following the forum dilligently in the past few weeks and keep wondering how X3 can be so super-stable for many and just doesn't seem to work right for others, often being exactly opposite from the X2a experience. With every PC DAW being unique, it's a tough call to find the root of the evil and sometimes system fixes you attempt even make it worse ...
 
Hence, I wonder if we could put together some sort of troubleshooting guide i.e. a list of problems vs. solutions for everyone in the forum to browse and review in order to improve their system.
 
So please list which

• system components
• driver versions
• urban legend system tweaks
• 3rd party programs (plugins, backup / tuning software, freeware, etc.)
• Sonar settings

have caused heartaches in form of performance issues and stability problems and how you detected it and eventually fixed it.
 
I'll throw in some of my experiences in a minute ...

Could we also separate and /or identify software versus hardware issues? For example, list hardware that is known to cause stability problems and others that are known to render satisfactory results? 
I think having hardware that do not makes Sonar happy might be one of the most difficult problems to detect and also very frustrating since sometimes you find them after heavy software tweaks. 

Hi CCR
 
That's part of the idea behind this thread (although not explicitly said). Pls, also list hardware and drivers that caused problems, how you could identify the troublemaker and what you did to fix it. Be brief and if there's information in another thread, just link it.
 
So hopefully a few posts down the road one can read through this like "ok, checked that ... and that ... and hey I haven't tried that yet" and in case of more detailed info required just follow links or PM whoever found the fix.
 
Thanks in advance to all who chime in and share their experiences

Problem: nVidia graphic card caused latency and hence audio drop-out
Fix: driver updates and card settings could not fix it; replaced by $30 ATI card
Detected with LatencyMon

Is this something you snagged from my persistent problems and my thread, or perhaps from your own experience? While I agree with this, this truly isn't a fix. Buying an ATI card over an nVidia card is a little extreme; although right now, I am considering it!

The V-64 was developed by a company that no longer is in business. There has been much talk about others wishing it would get updated to 64bit. But that just doesn't appear to be likely.

I love the sound of this plug also! Haven't had a problem with it yet.

There just has to be more to the 1920x1080 issue than meets the eye... it's just too specific in that it's hosing you guys up, but others like me have no problem at all.
 
Is it just win 8.0, 8.2, or does it affect some Win 7 folks as well? 
 
In the past, too high a resolution could negatively affect some real-time processes as the GPU ate up too much memory I/O bandwidth, but hell, this is 2013! I'm running a 2 1/2 yo 2.4Ghz Gateway AMD quad with MB AMD graphics and and I can load it up (with plugins) till my eyes glaze over (metaphorically speaking..). You have to wonder if there is something wonky with the video drivers - because it's the same Sonar we all run. It's possible, but unlikely that CW stumbled into some unexpected O/S system level changes - those things are usually trumpeted loudly and in advance on MSDN...
