I would like to post a Solution for a problem allot of people are experiencing in our vicinity .
Windows 10 seems to be automatic be updating the GPU drivers to 376.54. This update makes Solidworks really slow.
The solution seems to be to roll back to the previous version
Start > Control Panel > Device manager > Display Adapters > Nvidia Quadro XXXX > Properties > Driver > Rollback to previous version
when you manually install the driver windows sometimes updates the drivers again to the wrong/newer version
I hope this post will help people with the same issues to quickly solve there problems
