My solidworks is 2015 SP3 and laptop is Dell precision 7510 with M2000 Graphic card, but my solidwors runs very slow even if click a datum plane, it will takes a animation. I have updated the graphic driver as per solidoworks website, but the problem is still. who can help me?
the operation system of my laptop is Windows 10 64x
This may not be the reason for the slow performance but SolidWorks 2015 SP3 is not supported for Windows 10 as Windows 10 came out afterwards. SP5 is supported though as below, so see if you can upgrade to this via Help > Check for updates:
