SolidWorks 2016 long delay when selecting parts or faces

I am using SolidWorks 2016 SP3 and am having issues when selecting some parts and faces in an assembly, I am getting a long delay like SolidWorks is searching for the selection and then it finally finds it.

This is extremely annoying and I have tried turning off some options and so far nothing has helped.

Has anyone else noticed this issue and are there any workarounds?

Is this a know bug?

Below are my computer specs.

Also when I upgraded to SWX 2016 SP3 from 2015 SP5 I did a complete uninstall of 2015, cleaned the system and registry with CCleaner, updated my graphics card drivers to the latest from SWX Download and then did a clean install of 2016 SP3 and everything went very smoothly and this selection issue is the biggest problem I am having.

Dell Precision T5810

Intel Xeon E5-1630 v3 3.7GHz 4 Cores

Windows 7 Pro 64bit

NVidia K2200 Video Card (with the latest SolidWorks Drivers)

SolidWorks 2016 SP3

Thanks
