My workstation is a Dell Precision T5610, Xeon 3.5 GHz, 4 cores, Windows 10 Pro, 16Gb Ram, Nvidia Quadro K4000.
SW2018 is very slow when selecting and editing views and dimensions. Tech support helped tweak my system, but still haven't seen a difference.
I'm also using a wireless mouse (Logitech G602) and a 3DConnexion SpaceNavigator.
Have you checked if your view switched to ''Draft quality''? It generally gets very laggy when it does that for me.
Could you upload the part for someone else to verify if it occurs on their side too? If not, could you post some screenshots?
