Hi Dave,

worked it out. It was an issue with the primary display.
Latest update unchecked the primary display setting, result was using intel card for everything.
sequential disabling got it NVIDIA back in the driving seat.
Thanks for the quick responses earlier !

I'm running an NVIDIA GeForce GTX1050 running all of my OpenGL

Since the most recent Windows 10 update (using 2017 Pro), the select function (from single line to large groups) has developed a 5-10 second delay between click and highlight. All functionality suspended in this time.
Tried installing 2018 pro this morning on the off-chance that it wasn't a problem on the new release, same thing is happening.
I have tried changing the priority for sketch-up and dwm.exe to Real-time from Normal priority, this improves the delay to a steady 8 seconds.

has anyone got any idea on a fix for this before I lose my mind ?
