Got a new PC with Nvidia P1000 graphic card and it have very annoying feature. Every time I want to select a surface or line, Solidworks first has to draw/shown a line around the contour of the selected surface or line ( here shown as a green line). Have of couse tried the recommend drive from Solidworks and also the lastes driver from Nvidia, but the problem remains. So I aspect it's a "setting" issue - have tried all on/off setting I know, but the problem is still there :
Thanks for all the help, a Solidworks specialist point directly to the problem: On the System Option you can see that the "Use Software OpenGL" is checked - due to my previously PC didn't had a genuine OpenGL card. As soon I check off, everthing was running smoothly:
