I've been using SolidWorks 2015 sp5 for a few years on my laptop, but quite recently the performance has drastically dropped, seemingly overnight. There's nothing blatant I can think about that I've changed recently that could be the cause of this.
Laptop Specs: Lenovo Y50, windows 10, i7 processor, 16gbs of RAM, Nvidia 860 graphics card I believe.
I also run Inventor 2017 on this machine and that seems to still be working fine (though I greatly prefer Solidworks)
I've uninstalled and reinstalled and the problem persists.
Trying to edit sketches, simple movements (pan, zoom, ect.), and even selecting things from the feature manager are very choppy, laggy, and slow.
Please send help.
