I'm going to answer this as it may well help others, as well.
 
So, for this issue, what I did this time is:
 
- I did what Steve recommended... Reset built-in Nvidia Control Panel (P3D) settings.
- Removed Nvidia Inspector settings and loaded one provided by Rich.
- Additionally, unchecked Volumetric Clouds
 
So, everything is back to normal. No more tearing nor jiggling, and scenery becomes sharp quickly. Only issue is VAS, but of course we all know it will happen near high density airports and sceneries.  

OMG,  This is SOLVED !
 
I selected  "Aero Themes 7" and oh wow, this fixed the issue. No more tearing; no more jiggles- All stable. Unbelievable, I was about to give up after trying to fix it for almost a week. (And the worst part, I completely formatted my FSX drive- gone.. Never thought I would do that.. brings me tears).
 
Uffff, back in business. Now time to start installing add-ons starting with OBRX regions, ASN, and REX.
 
Thank you very much guys- especially J van E

I hope new comers- or even- current simmers are able to find this thread. And realize what a difference  selecting of "Aero Themes 7" can make.
 
Steve you do a great job explaining the cores, but read so far and my head started spinning, and since I don't have any settings to adjust in my brain, I'll just do as you recommend for the Affinity Mask and test.  (Thank you)
