What version of windows are you running? Windows 10 and I believe 8.1 in the task manager/performance tab will help see if there are any hardware "bottlenecks" such as a cpu core pegging 90%+ or maybe high disk usage as well as system ram.
I also like to use msi afterburner (free) to monitor gpu and cpu useage when trying to troubleshoot performance issues. If all the hardware information looks good, it can just be software optimizations that need to be made, but at least you will know if its your system aging or just SW2016 that may need some work.
In both W10 and 8.1 I see the problem. There is no other load.
SW2016 is just lagging unlike SW2015.
