Major performance drop SolidWorks 2015

Niko Bhagwandin Feb 13, 2017 7:16 AM

Hello all,

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.

Other people have reported problems with recent driver updates for the Geforce series of cards (which aren't officially supported, but others have had luck reverting to older drivers). See this thread for details:

I hope this helps,

(wow,.. seems to be a popular issue lately... )

(repeated on this thread.... SolidWorks is SUDDENLY very slow today )

What most likely happened,.. Windows Update auto installed the latest nvidia driver... unfortunately, there have been issues with nvidia drivers for the past 2 months. (newer is not always better)
... as suggested.. look at your driver version and look over the past discussions using the search (top right maginfy glass)... for instance, use the words, "slow driver" .
IMHO.. reinstall your older video driver,.. if you know what it was?... or undo the last update using system "restore"....
,,if you don't want to do a system restore.. download one of the older nvidia drivers from about mid last year (~June 2016)
.. if for some reason.. the above is not the answer.. it could be some sort of corruption to the registry... search the forum.. "reset registry"

Good luck!

  This could turn out to be a major "copy and paste" situation Paul
